Basis of Presentation	Basis of Presentation
	In the opinion of management, the information furnished in the accompanying condensed consolidated financial statements reflects all normal recurring adjustments that are necessary to fairly state the results for these interim periods and should be read in conjunction with Analog Devices, Inc.’s (the Company) Annual Report on Form 10-K for the fiscal year ended November 1, 2014 and related notes. The results of operations for the interim periods shown in this report are not necessarily indicative of the results that may be expected for the fiscal year ending October 31, 2015 or any future period.
	On July 22, 2014, the Company completed its acquisition of Hittite Microwave Corporation (Hittite), a company that designs and develops high performance integrated circuits, modules, subsystems and instrumentation for radio frequency, microwave and millimeterwave applications. The total consideration paid to acquire Hittite was approximately $2.4 billion, financed through a combination of existing cash on hand and a 90-day term loan facility of $2.0 billion. The acquisition of Hittite is referred to as the Acquisition. See Note 16, Acquisitions, of these Notes to Condensed Consolidated Financial Statements for further discussion related to the Acquisition.
	Certain amounts reported in previous periods have been reclassified to conform to the fiscal 2015 presentation. Such reclassified amounts are immaterial. The Company has a 52-53 week fiscal year that ends on the Saturday closest to the last day in October. Fiscal 2015 and fiscal 2014 are 52-week fiscal years.

Revenue_Recognition

Revenue Recognition [Abstract]
Revenue Recognition	Revenue Recognition
	Revenue from product sales to customers is generally recognized when title passes, which is upon shipment in the U.S. and for certain foreign countries. For other foreign countries, title passes subsequent to product shipment, ordinarily within a week of shipment. Accordingly, the Company defers the revenue recognized relating to these other foreign countries until title has passed. For multiple element arrangements, the Company allocates arrangement consideration among the elements based on the relative fair values of those elements as determined using vendor-specific objective evidence or third-party evidence. The Company uses its best estimate of selling price to allocate arrangement consideration between the deliverables in cases where neither vendor-specific objective evidence nor third-party evidence is available. A reserve for sales returns and allowances for customers is recorded based on historical experience or specific identification of an event necessitating a reserve.
	Revenue from contracts with the United States government, government prime contractors and some commercial customers is generally recorded on a percentage of completion basis using either units delivered or costs incurred as the measurement basis for progress towards completion. The output measure is used to measure results directly and is generally the best measure of progress toward completion in circumstances in which a reliable measure of output can be established. Estimated revenue in excess of amounts billed is reported as unbilled receivables. Contract accounting requires judgment in estimating costs and assumptions related to technical issues and delivery schedule. Contract costs include material, subcontract costs, labor and an allocation of indirect costs. The estimation of costs at completion of a contract is subject to numerous variables involving contract costs and estimates as to the length of time to complete the contract. Changes in contract performance, estimated gross margin, including the impact of final contract settlements, and estimated losses are recognized in the period in which the changes or losses are determined.
	In all regions of the world, the Company defers revenue and the related cost of sales on shipments to distributors until the distributors resell the products to their customers. As a result, the Company’s revenue fully reflects end customer purchases and is not impacted by distributor inventory levels. Sales to distributors are made under agreements that allow distributors to receive price-adjustment credits, as discussed below, and to return qualifying products for credit, as determined by the Company, in order to reduce the amounts of slow-moving, discontinued or obsolete product from their inventory. These agreements limit such returns to a certain percentage of the value of the Company’s shipments to that distributor during the prior quarter. In addition, distributors are allowed to return unsold products if the Company terminates the relationship with the distributor.
	Distributors are granted price-adjustment credits for sales to their customers when the distributor’s standard cost (i.e., the Company’s sales price to the distributor) does not provide the distributor with an appropriate margin on its sales to its customers. As distributors negotiate selling prices with their customers, the final sales price agreed upon with the customer will be influenced by many factors, including the particular product being sold, the quantity ordered, the particular customer, the geographic location of the distributor and the competitive landscape. As a result, the distributor may request and receive a price-adjustment credit from the Company to allow the distributor to earn an appropriate margin on the transaction.
	Distributors are also granted price-adjustment credits in the event of a price decrease subsequent to the date the product was shipped and billed to the distributor. Generally, the Company will provide a credit equal to the difference between the price paid by the distributor (less any prior credits on such products) and the new price for the product multiplied by the quantity of the specific product in the distributor’s inventory at the time of the price decrease.
	Given the uncertainties associated with the levels of price-adjustment credits to be granted to distributors, the sales price to the distributor is not fixed or determinable until the distributor resells the products to their customers. Therefore, the Company defers revenue recognition from sales to distributors until the distributors have sold the products to their customers.
	Title to the inventory transfers to the distributor at the time of shipment or delivery to the distributor, and payment from the distributor is due in accordance with the Company’s standard payment terms. These payment terms are not contingent upon the distributors’ sale of the products to their customers. Upon title transfer to distributors, inventory is reduced for the cost of goods shipped, the margin (sales less cost of sales) is recorded as “deferred income on shipments to distributors, net” and an account receivable is recorded. Shipping costs are charged to cost of sales as incurred.
	The deferred costs of sales to distributors have historically had very little risk of impairment due to the margins the Company earns on sales of its products and the relatively long life-cycle of the Company’s products. Product returns from distributors that are ultimately scrapped have historically been immaterial. In addition, price protection and price-adjustment credits granted to distributors historically have not exceeded the margins the Company earns on sales of its products. The Company continuously monitors the level and nature of product returns and is in frequent contact with the distributors to ensure reserves are established for all known material issues.
	As of January 31, 2015 and November 1, 2014, the Company had gross deferred revenue of $348.2 million and $349.7 million, respectively, and gross deferred cost of sales of $70.0 million and $71.3 million, respectively. Deferred income on shipments to distributors remained flat in the first three months of fiscal 2015 as distributor sales to end customers offset product shipments into the channel during the first quarter of fiscal 2015.
	The Company generally offers a twelve-month warranty for its products. The Company’s warranty policy provides for replacement of defective products. Specific accruals are recorded for known product warranty issues. Product warranty expenses during each of the three-month periods ended January 31, 2015 and February 1, 2014 were not material.

StockBased_Compensation

Stock-Based Compensation	3 Months Ended
	Jan. 31, 2015
Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
Stock-Based Compensation	Stock-Based Compensation
	Stock-based compensation is measured at the grant date based on the grant-date fair value of the awards ultimately expected to vest, and is recognized as an expense on a straight-line basis over the vesting period, which is generally five years for stock options and three years for restricted stock units. In addition to restricted stock units with a service condition, the Company grants restricted stock units with both a market condition and a service condition (market-based restricted stock units). The number of shares of the Company's common stock to be issued upon vesting of market-based restricted stock units will range from 0% to 200% of the target amount, based on the comparison of the Company's total shareholder return (TSR) to the median TSR of a specified peer group over a three-year period. TSR is a measure of stock price appreciation plus any dividends paid during the performance period. Determining the amount of stock-based compensation to be recorded for stock options and market-based restricted stock units requires the Company to develop estimates to calculate the grant-date fair value of awards.
	Modification of Awards — The Company has from time to time modified the vesting terms of its equity awards to employees and directors. The modifications made to the Company’s equity awards in the first three months of fiscal 2015 or 2014 did not result in significant incremental compensation costs, either individually or in the aggregate.
	Grant-Date Fair Value — The Company uses the Black-Scholes valuation model to calculate the grant-date fair value of stock option awards and the Monte Carlo simulation model to calculate the grant-date fair value of market-based restricted stock units. The use of these valuation models requires the Company to make estimates and assumptions, such as expected volatility, expected term, risk-free interest rate, expected dividend yield and forfeiture rates. The grant-date fair value of restricted stock units with only a service condition represents the value of the Company’s common stock on the date of grant, reduced by the present value of dividends expected to be paid on the Company’s common stock prior to vesting.
	Information pertaining to the Company’s stock option awards and the related estimated weighted-average assumptions to calculate the fair value of stock options using the Black-Scholes valuation model granted during the three-month periods ended January 31, 2015 and February 1, 2014 are as follows:
		Three Months Ended
	Stock Options	January 31, 2015				February 1, 2014
	Options granted (in thousands)	55				16
	Weighted-average exercise price		$51.23				$48.97
	Weighted-average grant-date fair value		$7.28				$7.06
	Assumptions:
	Weighted-average expected volatility	23.50%				23		%
	Weighted-average expected term (in years)	5.3				5.4
	Weighted-average risk-free interest rate	1.6		%		1.6		%
	Weighted-average expected dividend yield	2.9		%		2.7		%
	The Company utilizes the Monte Carlo simulation valuation model to value market-based restricted stock units. The Monte Carlo simulation model utilizes multiple input variables that determine the probability of satisfying the performance conditions stipulated in the award grant and calculates the fair market value for the market-based restricted stock units granted. The Monte Carlo simulation model also uses stock price volatility and other variables to estimate the probability of satisfying the performance conditions, including the possibility that the market condition may not be satisfied, and the resulting fair value of the award. Market-based restricted stock units were not granted during the three-month periods ended January 31, 2015 or February 1, 2014.
	Expected volatility — The Company is responsible for estimating volatility and has considered a number of factors, including third-party estimates. The Company currently believes that the exclusive use of implied volatility results in the best estimate of the grant-date fair value of employee stock options because it reflects the market’s current expectations of future volatility. In evaluating the appropriateness of exclusively relying on implied volatility, the Company concluded that: (1) options in the Company’s common stock are actively traded with sufficient volume on several exchanges; (2) the market prices of both the traded options and the underlying shares are measured at a similar point in time to each other and on a date close to the grant date of the employee share options; (3) the traded options have exercise prices that are both near-the-money and close to the exercise price of the employee share options; and (4) the remaining maturities of the traded options used to estimate volatility are at least one year.
	Expected term — The Company uses historical employee exercise and option expiration data to estimate the expected term assumption for the Black-Scholes grant-date valuation. The Company believes that this historical data is currently the best estimate of the expected term of a new option, and that generally its employees exhibit similar exercise behavior.
	Risk-free interest rate — The yield on zero-coupon U.S. Treasury securities for a period that is commensurate with the expected term assumption is used as the risk-free interest rate.
	Expected dividend yield — Expected dividend yield is calculated by annualizing the cash dividend declared by the Company’s Board of Directors for the current quarter and dividing that result by the closing stock price on the date of grant. Until such time as the Company’s Board of Directors declares a cash dividend for an amount that is different from the current quarter’s cash dividend, the current dividend will be used in deriving this assumption. Cash dividends are not paid on options, restricted stock or restricted stock units.
	Stock-Based Compensation Expense
	The amount of stock-based compensation expense recognized during a period is based on the value of the awards that are ultimately expected to vest. Forfeitures are estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates. The term “forfeitures” is distinct from “cancellations” or “expirations” and represents only the unvested portion of the surrendered stock-based award. Based on an analysis of its historical forfeitures, the Company has applied an annual forfeiture rate of 4.7% to all unvested stock-based awards as of January 31, 2015. The rate of 4.7% represents the portion that is expected to be forfeited over the vesting period. This analysis will be re-evaluated quarterly and the forfeiture rate will be adjusted as necessary. Ultimately, the actual expense recognized over the vesting period will only be for those options that vest.
	Additional paid-in-capital (APIC) Pool
	The APIC pool represents the excess tax benefits related to share-based compensation that are available to absorb future tax deficiencies. If the amount of future tax deficiencies is greater than the available APIC pool, the Company records the excess as income tax expense in its condensed consolidated statements of income. During the three-month periods ended January 31, 2015 and February 1, 2014, the Company had available APIC pool to absorb tax deficiencies recorded and as a result, these deficiencies did not affect its results of operations.
	Stock-Based Compensation Activity
	A summary of the activity under the Company’s stock option plans as of January 31, 2015 and changes during the three-month period then ended is presented below:
	Activity during the Three Months Ended January 31, 2015	Options			Weighted-				Weighted-	Aggregate

	Options vested or expected to vest at January 31, 2015 (1)	12,438				$37.41			5.7		$182,829
	-1	In addition to the vested options, the Company expects a portion of the unvested options to vest at some point in the future. The number of options expected to vest is calculated by applying an estimated forfeiture rate to the unvested options.
	During the three months ended January 31, 2015, the total intrinsic value of options exercised (i.e., the difference between the market price at exercise and the price paid by the employee to exercise the options) was $29.7 million, and the total amount of proceeds received by the Company from the exercise of these options was $42.8 million.
	During the three months ended February 1, 2014, the total intrinsic value of options exercised (i.e., the difference between the market price at exercise and the price paid by the employee to exercise the options) was $44.9 million, and the total amount of proceeds received by the Company from the exercise of these options was $79.6 million.
	A summary of the Company’s restricted stock unit award activity as of January 31, 2015 and changes during the three-month period then ended is presented below:
	Activity during the Three Months Ended January 31, 2015	Restricted			Weighted-

	Forfeited	(68	)			$44.77
	Restricted stock units outstanding at January 31, 2015	2,966				$43.37
	As of January 31, 2015, there was $102.8 million of total unrecognized compensation cost related to unvested share-based awards comprised of stock options and restricted stock units. That cost is expected to be recognized over a weighted-average period of 1.3 years. The total grant-date fair value of shares that vested during the three months ended January 31, 2015 was approximately $16.6 million. The total grant-date fair value of shares that vested during the three months ended February 1, 2014 was approximately $39.5 million.

Common Stock Repurchase [Abstract]
Common Stock Repurchase	Common Stock Repurchase
	The Company’s common stock repurchase program has been in place since August 2004. In the aggregate, the Board of Directors has authorized the Company to repurchase $5.6 billion of the Company’s common stock under the program. Under the program, the Company may repurchase outstanding shares of its common stock from time to time in the open market and through privately negotiated transactions. Unless terminated earlier by resolution of the Company’s Board of Directors, the repurchase program will expire when the Company has repurchased all shares authorized under the program. As of January 31, 2015, the Company had repurchased a total of approximately 138.1 million shares of its common stock for approximately $4.9 billion under this program. As of January 31, 2015, an additional $693.2 million remains available for repurchase of shares under the current authorized program. The repurchased shares are held as authorized but unissued shares of common stock. The Company also, from time to time, repurchases shares in settlement of employee minimum tax withholding obligations due upon the vesting of restricted stock units or the exercise of stock options. The withholding amount is based on the employee's minimum statutory withholding requirement. Any future common stock repurchases will be dependent upon several factors, including the Company's financial performance, outlook, liquidity and the amount of cash the Company has available in the United States.

	a) The gain related to a fixed asset purchase was reclassified out of accumulated other comprehensive income (loss) to fixed assets which will depreciate into earnings over its expected useful life.
	b) The amortization of pension components is included in the computation of net periodic pension cost. For further information see Note 13, Retirement Plans, contained in Item 8 of the Annual Report on Form 10-K for the fiscal year ended November 1, 2014.
	The Company estimates $12.4 million of net derivative unrealized holding losses included in OCI will be reclassified into earnings within the next twelve months. There was no ineffectiveness in the three-month periods ended January 31, 2015 and February 1, 2014.
	Unrealized gains and losses on available-for-sale securities classified as short-term investments at January 31, 2015 and November 1, 2014 are as follows:
		January 31, 2015				November 1, 2014
	Unrealized gains on securities classified as short-term investments	$	366			$	541
	Unrealized losses on securities classified as short-term investments	(510		)		(407		)
	Net unrealized (losses) gains on securities classified as short-term investments	$	(144	)		$	134
	As of January 31, 2015, the Company held 72 investment securities, 19 of which were in an unrealized loss position with gross unrealized loss of $0.5 million and an aggregate fair value of $688.1 million. As of November 1, 2014, the Company held 66 investment securities, 18 of which were in an unrealized loss position with gross unrealized loss of $0.4 million and an aggregate fair value of $694.7 million. These unrealized losses were primarily related to corporate obligations that earn lower interest rates than current market rates. None of these investments have been in a loss position for more than twelve months. As the Company does not intend to sell these investments and it is unlikely that the Company will be required to sell the investments before recovery of their amortized basis, which will be at maturity, the Company does not consider those investments to be other-than-temporarily impaired at January 31, 2015 and November 1, 2014.
	Realized gains or losses on investments are determined based on the specific identification basis and are recognized in nonoperating expense (income). There were no material net realized gains or losses from the sales of available-for-sale investments during any of the fiscal periods presented.

Earnings Per Share [Abstract]
Earnings Per Share	Earnings Per Share
	Basic earnings per share is computed based only on the weighted average number of common shares outstanding during the period. Diluted earnings per share is computed using the weighted average number of common shares outstanding during the period, plus the dilutive effect of potential future issuances of common stock relating to stock option programs and other potentially dilutive securities using the treasury stock method. In calculating diluted earnings per share, the dilutive effect of stock options is computed using the average market price for the respective period. In addition, the assumed proceeds under the treasury stock method include the average unrecognized compensation expense of stock options that are in-the-money and restricted stock units. This results in the “assumed” buyback of additional shares, thereby reducing the dilutive impact of in-the-money stock options. Potential shares related to certain of the Company’s outstanding stock options were excluded because they were anti-dilutive. Those potential shares, determined based on the weighted average exercise prices during the respective periods, related to the Company’s outstanding stock options could be dilutive in the future.
	The following table sets forth the computation of basic and diluted earnings per share:

Restructuring and Related Activities [Abstract]
Special Charges	Special Charges
	The Company monitors global macroeconomic conditions on an ongoing basis and continues to assess opportunities for improved operational effectiveness and efficiency, as well as a better alignment of expenses with revenues. As a result of these assessments, the Company has undertaken various restructuring actions over the past several years. These actions are described below.
	The following tables display the special charges taken for ongoing actions and a roll-forward from November 1, 2014 to January 31, 2015 of the employee separation and exit cost accruals established related to these actions.

	Reduction of Operating Costs
	During fiscal 2014, the Company recorded special charges of approximately $37.3 million. These special charges included $37.9 million for severance and fringe benefit costs in accordance with the Company's ongoing benefit plan or statutory requirements at foreign locations for 341 manufacturing, engineering and selling, marketing, general and administrative (SMG&A) employees; $0.5 million for lease obligation costs for facilities that the Company ceased using during the fourth quarter of fiscal 2014; and $0.4 million for the impairment of assets that have no future use located at closed facilities. The Company reversed approximately $1.4 million of its severance accrual related to charges taken in fiscal 2013 primarily due to severance costs being lower than the Company's estimates. As of January 31, 2015, the Company still employed 61 of the 341 employees included in these cost reduction actions. These employees must continue to be employed by the Company until their employment is involuntarily terminated in order to receive the severance benefit.

Segment Reporting [Abstract]
Segment Information	Segment Information
	In the first quarter of 2015, the Company implemented organizational changes designed to accelerate the Company's growth by increasing the speed and impact of its technological innovation. The organizational changes combine the Company's market and technology teams to better position engineers with customers in order to address the evolving needs of the markets the Company serves. As a result of these organizational changes, the Company re-evaluated its reporting structure under the new organization and concluded that the Company continues to operate in one reportable segment based on the aggregation of six operating segments. The Company designs, develops, manufactures and markets a broad range of integrated circuits. The Chief Executive Officer has been identified as the Company's Chief Operating Decision Maker. The Company has determined that all of the Company's operating segments share the following similar economic characteristics, and therefore meet the criteria established for operating segments to be aggregated into one reportable segment, namely:
	•The primary source of revenue for each operating segment is the sale of integrated circuits.
	•The integrated circuits sold by each of the Company's operating segments are manufactured using similar semiconductor manufacturing processes and raw materials in either the Company’s own production facilities or by third-party wafer fabricators using proprietary processes.
	•The Company sells its products to tens of thousands of customers worldwide. Many of these customers use products spanning all operating segments in a wide range of applications.
	•The integrated circuits marketed by each of the Company's operating segments are sold globally through a direct sales force, third-party distributors, independent sales representatives and via our website to the same types of customers.
	All of the Company's operating segments share a similar long-term financial model as they have similar economic characteristics. The causes for variation in operating and financial performance are the same among the Company's operating segments and include factors such as (i) life cycle and price and cost fluctuations, (ii) number of competitors, (iii) product differentiation and (iv) size of market opportunity. Additionally, each operating segment is subject to the overall cyclical nature of the semiconductor industry. Lastly, the number and composition of employees and the amounts and types of tools and materials required for production of products are similar for each operating segment.
	Revenue Trends by End Market
	The following table summarizes revenue by end market. The categorization of revenue by end market is determined using a variety of data points including the technical characteristics of the product, the “sold to” customer information, the “ship to” customer information and the end customer product or application into which the Company’s product will be incorporated. As data systems for capturing and tracking this data evolve and improve, the categorization of products by end market can vary over time. When this occurs, the Company reclassifies revenue by end market for prior periods. Such reclassifications typically do not materially change the sizing of, or the underlying trends of results within, each end market.

Fair Value Disclosures [Abstract]
Fair Value	Fair Value
	The Company defines fair value as the price that would be received to sell an asset or be paid to transfer a liability in an orderly transaction between market participants at the measurement date. The Company applies the following fair value hierarchy, which prioritizes the inputs used to measure fair value into three levels and bases the categorization within the hierarchy upon the lowest level of input that is available and significant to the fair value measurement. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements).
	Level 1 — Level 1 inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities that the reporting entity has the ability to access at the measurement date.
	Level 2 — Level 2 inputs are inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly. If the asset or liability has a specified (contractual) term, a Level 2 input must be observable for substantially the full term of the asset or liability.
	Level 3 — Level 3 inputs are unobservable inputs for the asset or liability in which there is little, if any, market activity for the asset or liability at the measurement date.
	The tables below set forth by level the Company’s financial assets and liabilities, excluding accrued interest components, that are accounted for at fair value on a recurring basis as of January 31, 2015 and November 1, 2014. The tables exclude cash on hand and assets and liabilities that are measured at historical cost or any basis other than fair value. As of January 31, 2015 and November 1, 2014, the Company held $84.6 million and $121.3 million, respectively, of cash and held-to-maturity investments that were excluded from the tables below.

The following methods and assumptions were used by the Company in estimating its fair value disclosures for financial instruments:
Cash equivalents and short-term investments — These investments are adjusted to fair value based on quoted market prices or are determined using a yield curve model based on current market rates.
Deferred compensation plan investments — The fair value of these mutual fund, money market fund and equity investments are based on quoted market prices.
Forward foreign currency exchange contracts — The estimated fair value of forward foreign currency exchange contracts, which includes derivatives that are accounted for as cash flow hedges and those that are not designated as cash flow hedges, is based on the estimated amount the Company would receive if it sold these agreements at the reporting date taking into consideration current interest rates as well as the creditworthiness of the counterparty for assets and the Company’s creditworthiness for liabilities. The fair value of these instruments is based upon valuation models using current market information such as strike price, spot rate, maturity date and volatility.
Interest rate swap agreements — The fair value of interest rate swap agreements is based on the quoted market price for the same or similar financial instruments.
Contingent consideration — The fair value of the contingent consideration was estimated utilizing the income approach and is based upon significant inputs not observable in the market. The income approach is based on two steps. The first step involves a projection of the cash flows that is based on the Company’s estimates of the timing and probability of achieving the defined milestones. The second step involves converting the cash flows into a present value equivalent through discounting. The discount rate reflects the Baa costs of debt plus the relevant risk associated with the asset and the time value of money.
The fair value measurement of the contingent consideration encompasses the following significant unobservable inputs:
Unobservable Inputs	Range
Estimated contingent consideration payments	$5,000
Discount rate	0% - 10%
Timing of cash flows	1 - 2 years
Probability of achievement	100%
Changes in the fair value of the contingent consideration subsequent to the acquisition date that are primarily driven by assumptions pertaining to the achievement of the defined milestones will be recognized in operating income in the period of the estimated fair value change. Significant increases or decreases in any of the inputs in isolation may result in a fluctuation in the fair value measurement.
The following table summarizes the change in the fair value of the contingent consideration measured using significant unobservable inputs (Level 3) from November 1, 2014 to January 31, 2015:
	Contingent

Financial Instruments Not Recorded at Fair Value on a Recurring Basis
On April 4, 2011, the Company issued $375.0 million aggregate principal amount of 3.0% senior unsecured notes due April 15, 2016 (the 2016 Notes) with semi-annual fixed interest payments due on April 15 and October 15 of each year, commencing October 15, 2011. Based on quotes received from third-party banks, the fair value of the 2016 Notes as of January 31, 2015 and November 1, 2014 was $383.6 million and $386.3 million, respectively, and is classified as a Level 1 measurement according to the fair value hierarchy.
On June 3, 2013, the Company issued $500.0 million aggregate principal amount of 2.875% senior unsecured notes due June 1, 2023 (the 2023 Notes) with semi-annual fixed interest payments due on June 1 and December 1 of each year, commencing December 1, 2013. Based on quotes received from third-party banks, the fair value of the 2023 Notes as of January 31, 2015 and November 1, 2014 was $506.0 million and $483.5 million, respectively, and is classified as a Level 1 measurement according to the fair value hierarchy.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivatives	Derivatives
	Foreign Exchange Exposure Management — The Company enters into forward foreign currency exchange contracts to offset certain operational and balance sheet exposures from the impact of changes in foreign currency exchange rates. Such exposures result from the portion of the Company’s operations, assets and liabilities that are denominated in currencies other
	than the U.S. dollar, primarily the Euro; other significant exposures include the Philippine Peso, the Japanese Yen and the British Pound. These foreign currency exchange contracts are entered into to support transactions made in the normal course of business, and accordingly, are not speculative in nature. The contracts are for periods consistent with the terms of the underlying transactions, generally one year or less. Hedges related to anticipated transactions are designated and documented at the inception of the respective hedges as cash flow hedges and are evaluated for effectiveness monthly. Derivative instruments are employed to eliminate or minimize certain foreign currency exposures that can be confidently identified and quantified. As the terms of the contract and the underlying transaction are matched at inception, forward contract effectiveness is calculated by comparing the change in fair value of the contract to the change in the forward value of the anticipated transaction, with the effective portion of the gain or loss on the derivative reported as a component of accumulated OCI in shareholders’ equity and reclassified into earnings in the same period during which the hedged transaction affects earnings. Any residual change in fair value of the instruments, or ineffectiveness, is recognized immediately in other (income) expense. Additionally, the Company enters into forward foreign currency contracts that economically hedge the gains and losses generated by the re-measurement of certain recorded assets and liabilities in a non-functional currency. Changes in the fair value of these undesignated hedges are recognized in other (income) expense immediately as an offset to the changes in the fair value of the asset or liability being hedged. As of January 31, 2015 and November 1, 2014, the total notional amount of these undesignated hedges was $38.7 million and $45.2 million, respectively. The fair value of these undesignated hedges in the Company’s condensed consolidated balance sheets as of January 31, 2015 was $0.7 million and was immaterial as of November 1, 2014.
	Interest Rate Exposure Management — The Company's current and future debt may be subject to interest rate risk. The Company utilizes interest rate derivatives to alter interest rate exposure in an attempt to reduce the effects of these changes.
	On October 28, 2014, the Company entered into forward starting interest rate swap transactions to hedge its exposure to the variability in future cash flows due to changes in interest rates for debt issuances expected to occur in the future. Amounts reported in OCI related to these derivatives will be reclassified from OCI to earnings as interest expense is incurred on the forecasted hedged fixed-rate debt, adjusting interest expense to reflect the fixed-rate entered into by the forward starting swaps. These cash flow instruments hedge forecasted interest payments to be made through 2025. These forward starting swaps will be terminated on the day the hedged forecasted debt issuances occur, but no later than December 1, 2015, if the hedged forecasted debt issuances do not occur. The total notional value of these hedges as of January 31, 2015 and November 1, 2014 was $500.0 million. The fair value of these hedges was $38.1 million as of January 31, 2015 , included in accrued liabilities, and $1.7 million as of November 1, 2014, included in other assets, in the Company's condensed consolidated balance sheet.
	On April 24, 2013, the Company entered into a treasury rate lock agreement with Bank of America. This agreement allowed the Company to lock a 10-year US Treasury rate of 1.7845% through June 14, 2013 for its anticipated issuance of the 2023 Notes. The Company designated this agreement as a cash flow hedge. On June 3, 2013, the Company terminated the treasury rate lock simultaneously with the issuance of the 2023 Notes which resulted in a gain of approximately $11.0 million. This gain is being amortized into interest expense over the 10-year term of the 2023 Notes. See Note 5, Accumulated Other Comprehensive Income (Loss), for more information relating to the amortization of the treasury rate lock into interest expense.
	The market risk associated with the Company’s derivative instruments results from currency exchange rate or interest rate movements that are expected to offset the market risk of the underlying transactions, assets and liabilities being hedged. The counterparties to the agreements relating to the Company’s derivative instruments consist of a number of major international financial institutions with high credit ratings. Based on the credit ratings of the Company’s counterparties as of January 31, 2015, nonperformance is not perceived to be a significant risk. Furthermore, none of the Company’s derivatives are subject to collateral or other security arrangements and none contain provisions that are dependent on the Company’s credit ratings from any credit rating agency. While the contract or notional amounts of derivative financial instruments provide one measure of the volume of these transactions, they do not represent the amount of the Company’s exposure to credit risk. The amounts potentially subject to credit risk (arising from the possible inability of counterparties to meet the terms of their contracts) are generally limited to the amounts, if any, by which the counterparties’ obligations under the contracts exceed the obligations of the Company to the counterparties. As a result of the above considerations, the Company does not consider the risk of counterparty default to be significant.
	The Company records the fair value of its derivative financial instruments in its condensed consolidated financial statements in other current assets, other assets or accrued liabilities, depending on their net position, regardless of the purpose or intent for holding the derivative contract. Changes in the fair value of the derivative financial instruments are either recognized periodically in earnings or in shareholders’ equity as a component of OCI. Changes in the fair value of cash flow hedges are recorded in OCI and reclassified into earnings when the underlying contract matures. Changes in the fair values of derivatives not qualifying for hedge accounting or the ineffective portion of designated hedges are reported in earnings as they occur.
	The total notional amounts of forward foreign currency derivative instruments designated as hedging instruments of cash flow hedges denominated in Euros, British Pounds, Philippine Pesos and Japanese Yen as of January 31, 2015 and November 1, 2014 was $177.9 million and $183.5 million, respectively. The fair values of forward foreign currency derivative instruments designated as hedging instruments in the Company’s condensed consolidated balance sheets as of January 31, 2015 and November 1, 2014 were as follows:
				Fair Value At
		Balance Sheet Location		January 31, 2015				1-Nov-14
	Forward foreign currency exchange contracts	Accrued liabilities		$	17,170			$	10,584
	For information on the unrealized holding gains (losses) on derivatives included in and reclassified out of accumulated other comprehensive income into the condensed consolidated statement of income related to forward foreign currency exchange contracts, see Note 5, Accumulated Other Comprehensive Income (Loss).
	All of the Company’s derivative financial instruments are subject to master netting arrangements that allow the Company and its counterparties to net settle amounts owed to each other. Derivative assets and liabilities that can be net settled under these arrangements have been presented in the Company's consolidated balance sheet on a net basis. As of January 31, 2015 and November 1, 2014, none of the master netting arrangements involved collateral. The following table presents the gross amounts of the Company's derivative assets and liabilities and the net amounts recorded in our consolidated balance sheet:

Goodwill and Intangible Assets	Goodwill and Intangible Assets
	Goodwill
	The Company evaluates goodwill for impairment annually, as well as whenever events or changes in circumstances suggest that the carrying value of goodwill may not be recoverable. The Company tests goodwill for impairment at the reporting unit level (operating segment or one level below an operating segment) on an annual basis on the first day of the fourth quarter (on or about August 1) or more frequently if indicators of impairment exist. In the first quarter of 2015, the Company implemented organizational changes designed to accelerate the Company's growth by increasing the speed and impact of its technological innovation. The organizational changes combine the Company's market and technology teams to address the evolving needs of the markets and customers the Company serves. The Company performed an impairment analysis immediately prior to and subsequent to the reorganization and evaluated goodwill for impairment as of the date of reorganization. The Company identified its reporting units to be its six operating segments. The performance of the test involves a two-step process. The first step of the impairment test involves comparing the fair values of the applicable reporting units with their aggregate carrying values, including goodwill. The Company determines the fair value of its reporting units using the income approach methodology of valuation that includes the discounted cash flow method, as well as other generally accepted valuation methodologies. If the carrying amount of a reporting unit exceeds the reporting unit’s fair value, the Company performs the second step of the goodwill impairment test to determine the amount of impairment loss. The second step of the goodwill impairment test involves comparing the implied fair value of the affected reporting unit with the carrying value of that reporting unit. Based on this analysis, no impairment was identified. The Company's next annual impairment assessment will be performed as of the first day of the fourth quarter of fiscal 2015 unless indicators arise that would require the Company to re-evaluate at an earlier date. The following table presents the changes in goodwill during the first three months of fiscal 2015:
		Three Months Ended

	Balance as of January 31, 2015	$	1,641,793
	(1) Represents changes to goodwill as a result of finalizing working capital adjustments related to this acquisition.
	Intangible Assets
	The Company reviews finite-lived intangible assets for impairment whenever events or changes in circumstances indicate that the carrying value of assets may not be recoverable. Recoverability of these assets is determined by comparison of their carrying value to future undiscounted cash flows the assets are expected to generate over their remaining economic lives. If such assets are considered to be impaired, the impairment to be recognized in earnings equals the amount by which the carrying value of the assets exceeds their fair value determined by either a quoted market price, if any, or a value determined by utilizing a discounted cash flow technique. As of January 31, 2015 and November 1, 2014, the Company’s finite-lived intangible assets consisted of the following:
		January 31, 2015					November 1, 2014
		Gross Carrying			Accumulated		Gross Carrying		Accumulated
		Amount			Amortization		Amount		Amortization
	Customer relationships	$	624,900		$	36,838	$	624,900	$	19,473
	Technology-based	16,200			2,626		16,200		1,627

	Total	$	666,600		$	52,993	$	666,600	$	28,254
	For the three-month periods ended January 31, 2015 and February 1, 2014, amortization expense related to finite-lived intangible assets was $24.7 million and $0.1 million, respectively. The remaining amortization expense will be recognized over an estimated weighted average life of approximately 4.2 years.
	The Company expects annual amortization expense for intangible assets to be:
	Fiscal Year	Amortization Expense
	Remainder of fiscal 2015		$67,042
	2016		$73,428
	2017		$73,300
	2018		$72,149
	2019		$69,433
	2020		$69,433
	Indefinite-lived intangible assets are tested for impairment on an annual basis on the first day of the fourth quarter (on or about August 1) or more frequently if indicators of impairment exist. The impairment test involves the comparison of the fair values of the intangible assets with their carrying amount. No impairment of intangible assets resulted from the impairment tests in any of the fiscal years presented.
	Intangible assets, excluding in-process research and development (IPR&D), are amortized on a straight-line basis over their estimated useful lives or on an accelerated method of amortization that is expected to reflect the estimated pattern of economic use. IPR&D assets are considered indefinite-lived intangible assets until completion or abandonment of the associated research and development (R&D) efforts. Upon completion of the projects, the IPR&D assets will be amortized over their estimated useful lives.
	Indefinite-lived intangible assets consisted of $32.8 million and $33.1 million of IPR&D as of January 31, 2015 and November 1, 2014, respectively.

Revolving Credit Facility	Revolving Credit Facility
	As of January 31, 2015, the Company had $2.9 billion of cash and cash equivalents and short-term investments, of which $741.0 million was held in the United States. The balance of the Company's cash and cash equivalents and short-term investments was held outside the United States in various foreign subsidiaries. As the Company intends to reinvest its foreign earnings indefinitely, this cash is not available to meet the Company's cash requirements in the United States, including cash dividends and common stock repurchases. On December 19, 2012, the Company entered into a five-year, $500.0 million senior unsecured revolving credit facility with certain institutional lenders (the Credit Agreement). In June 2014, the Company amended this credit facility to temporarily increase the amount of allowed subsidiary indebtedness related to the financing of the Acquisition. To date, the Company has not borrowed under this credit facility but the Company may borrow in the future and use the proceeds for repayment of existing indebtedness, stock repurchases, acquisitions, capital expenditures, working capital and other lawful corporate purposes. Revolving loans under the Credit Agreement (other than swing line loans) bear interest, at the Company's option, at either a rate equal to (a) the Eurodollar Rate (as defined in the Credit Agreement) plus a margin based on the Company's debt rating or (b) the Base Rate (defined as the highest of (i) the Bank of America prime rate, (ii) the Federal Funds Rate (as defined in the Credit Agreement) plus .50% or (iii) one month Eurodollar Rate plus 1.00%) plus a margin based on the Company's debt rating. The terms of the facility impose restrictions on the Company’s ability to undertake certain transactions, to create certain liens on assets and to incur certain subsidiary indebtedness. In addition, the Credit Agreement contains a consolidated leverage ratio covenant of total consolidated funded debt to consolidated earnings before interest, taxes, depreciation, and amortization (EBITDA) of not greater than 3.0 to 1.0. As of January 31, 2015, the Company was compliant with these covenants.

	On April 4, 2011, the Company issued $375.0 million aggregate principal amount of 3.0% senior unsecured notes due April 15, 2016 (the 2016 Notes) with semi-annual fixed interest payments due on April 15 and October 15 of each year, commencing October 15, 2011. The sale of the 2016 Notes was made pursuant to the terms of an underwriting agreement, dated March 30, 2011, between the Company and Credit Suisse Securities (USA) LLC and Merrill Lynch, Pierce, Fenner and Smith Incorporated, as representative of the several underwriters named therein. The net proceeds of the offering were $370.5 million, after issuing at a discount and deducting expenses, underwriting discounts and commissions, which will be amortized over the term of the 2016 Notes. The indenture governing the 2016 Notes contains covenants that may limit the Company’s ability to: incur, create, assume or guarantee any debt for borrowed money secured by a lien upon a principal property; enter into sale and lease-back transactions with respect to a principal property; and consolidate with or merge into, or transfer or lease all or substantially all of its assets to, any other party. As of January 31, 2015, the Company was compliant with these covenants. The 2016 Notes are subordinated to any future secured debt and to the other liabilities of the Company’s subsidiaries.
	On June 3, 2013, the Company issued $500.0 million aggregate principal amount of 2.875% senior unsecured notes due June 1, 2023 (the 2023 Notes) with semi-annual fixed interest payments due on June 1 and December 1 of each year, commencing December 1, 2013. Prior to issuing the 2023 Notes, on April 24, 2013, the Company entered into a treasury rate lock agreement with Bank of America. This agreement allowed the Company to lock a 10-year US Treasury rate of 1.7845% through June 14, 2013 for its anticipated issuance of the 2023 Notes. Upon issuing the 2023 Notes, the Company simultaneously terminated the treasury rate lock agreement resulting in a gain of approximately $11.0 million. This gain will be amortized into interest expense over the 10-year term of the 2023 Notes. The sale of the 2023 Notes was made pursuant to the terms of an underwriting agreement, dated as of May 22, 2013, among the Company and J.P. Morgan Securities LLC, Merrill Lynch, Pierce, Fenner & Smith Incorporated and Credit Suisse Securities (USA) LLC, as the representatives of the several underwriters named therein. The net proceeds of the offering were $493.9 million, after discount and issuance costs. Debt discount and issuance costs will be amortized through interest expense over the term of the 2023 Notes. The indenture governing the 2023 Notes contains covenants that may limit the Company's ability to: incur, create, assume or guarantee any debt for borrowed money secured by a lien upon a principal property; enter into sale and lease-back transactions with respect to a principal property; and consolidate with or merge into, or transfer or lease all or substantially all of its assets to, any other party. As of January 31, 2015, the Company was compliant with these covenants. The notes are subordinated to any future secured debt and to the other liabilities of the Company's subsidiaries.
	On July 22, 2014, the Company entered into a 90-day term loan facility in an aggregate principal amount of $2.0 billion with Credit Suisse AG, as Administrative Agent, and each lender from time to time party thereto (the Term Loan Agreement) to finance the Acquisition. The outstanding balance due under the Term Loan Agreement was repaid on August 29, 2014. Loans under the Term Loan Agreement bore interest at the Eurodollar Rate (as defined in the Term Loan Agreement) plus 1.00% (1.16% as of August 2, 2014). Payments of the principal amounts of revolving loans under the Term Loan Agreement were due no later than October 20, 2014 and did not require interim amortization. Expenses incurred related to the debt were amortized over the 90-day term. The Term Loan Agreement contained customary representations and warranties and affirmative and negative covenants, including, among others, limitations on liens, indebtedness of subsidiaries, mergers and other fundamental changes, sales and other dispositions of property or assets and transactions with affiliates. The Term Loan Agreement contained a consolidated leverage ratio covenant of total consolidated funded debt to consolidated earnings before interest, taxes, depreciation, and amortization (EBITDA) of not greater than 3.0 to 1.0.
	The Company’s principal payments related to its debt obligations are as follows: $375.0 million in fiscal 2016 and $500.0 million in fiscal 2023.

Inventory Disclosure [Abstract]
Inventory Disclosure [Text Block]	Inventories
	Inventories are valued at the lower of cost (first-in, first-out method) or market. The valuation of inventory requires the Company to estimate obsolete or excess inventory as well as inventory that is not of saleable quality. The Company employs a variety of methodologies to determine the net realizable value of its inventory. While a portion of the calculation to record inventory at its net realizable value is based on the age of the inventory and lower of cost or market calculations, a key factor in estimating obsolete or excess inventory requires the Company to estimate the future demand for its products. If actual demand is less than the Company’s estimates, impairment charges, which are recorded to cost of sales, may need to be recorded in future periods. Inventory in excess of saleable amounts is not valued, and the remaining inventory is valued at the lower of cost or market. Approximately $8.8 million of raw materials have been classified as non-current and are presented within the condensed consolidated balance sheet as other assets as the Company does not expect this inventory to be sold within one year. This inventory was purchased as part of a planned transition from a principal foundry supplier and was acquired by the Company through the Acquisition. The larger than normal purchase was made to maintain an adequate supply of the raw material for customers, which has a natural life of five to ten years.
	Inventories at January 31, 2015 and November 1, 2014 were as follows:
		January 31, 2015		November 1, 2014

	Hittite Microwave Corporation
	On July 22, 2014, the Company completed its acquisition of Hittite Microwave Corporation (Hittite), a company that designs and develops high performance integrated circuits, modules, subsystems and instrumentation for radio frequency, microwave and millimeterwave applications. The total consideration paid to acquire Hittite was approximately $2.4 billion, financed through a combination of existing cash on hand and a 90-day term loan facility of $2.0 billion. The Acquisition is expected to expand the Company’s technology position in high performance signal processing solutions and drive growth in key markets. The Company completed the Acquisition through a cash tender offer (the Offer) by BBAC Corp., a wholly-owned subsidiary of the Company, for all of the outstanding shares of common stock, par value $0.01 per share, of Hittite at a purchase price of $78.00 per share, net to the seller in cash, without interest, less any applicable withholding taxes. After completion of the Offer, BBAC Corp. merged with and into Hittite, with Hittite continuing as the surviving corporation and a wholly-owned subsidiary of the Company.
	During the first quarter of fiscal 2015, the Company recorded an acquisition accounting adjustment of $3.8 million to deferred income taxes and goodwill. The Acquisition accounting is not complete and additional information that existed at the acquisition date may become known to the Company during the remainder of the measurement period. As of the filing date of this Quarterly Report on Form 10-Q, the Company is still in the process of valuing the assets acquired of Hittite's business, including inventory, deferred income taxes, and assumed liabilities.

Income Taxes	Income Taxes
	The Company has provided for potential tax liabilities due in the various jurisdictions in which the Company operates. Judgment is required in determining the worldwide income tax expense provision. In the ordinary course of global business, there are many transactions and calculations where the ultimate tax outcome is uncertain. Some of these uncertainties arise as a consequence of cost reimbursement arrangements among related entities. Although the Company believes its estimates are reasonable, no assurance can be given that the final tax outcome of these matters will not be different from that which is reflected in the historical income tax provisions and accruals. Such differences could have a material impact on the Company’s income tax provision and operating results in the period in which such determination is made.
	The Company’s effective tax rate reflects the applicable tax rate in effect in the various tax jurisdictions around the world where our income is earned. The Company's effective tax rate for all periods presented is lower than the U.S. federal statutory rate of 35%, primarily due to lower statutory tax rates applicable to the Company's operations in jurisdictions in which the Company earns income.
	The Company has filed a petition with the U.S. Tax Court for one open matter for fiscal years 2006 and 2007 that pertains to Section 965 of the Internal Revenue Code related to the beneficial tax treatment of dividends paid from foreign owned companies under The American Jobs Creation Act. The potential liability for this adjustment is $36.5 million. On September 18, 2013, in a matter not involving the Company, the U.S. Tax Court held that accounts receivable created under Rev. Proc. 99-32 may constitute indebtedness for purposes of Section 965 (b)(3) of the Internal Revenue Code and that the IRS was not precluded from reducing the beneficial dividend-received deduction because of the increase in related-party indebtedness (BMC Software Inc. v Commissioner, 141 T.C. No. 5 2013). After analyzing the Tax Court’s decision, the Company has determined that its tax position with respect to Section 965(b)(3) no longer meets the more likely than not standard of recognition for accounting purposes. Accordingly, the Company recorded a $36.5 million reserve for this matter in the fourth quarter of fiscal 2013.
	All of the Company's U.S. federal tax returns prior to fiscal year 2011 are no longer subject to examination.

	In July 2013, the Financial Accounting Standards Board (FASB) issued ASU No. 2013-11 (ASU No. 2013-11), Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists . ASU No. 2013-11 requires that an unrecognized tax benefit, or a portion of an unrecognized tax benefit, should be presented as a reduction to a deferred tax asset for a net operating loss carryforward, a similar tax loss or a tax credit carryforward, with certain exceptions. ASU No. 2013-11 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2013, which is the Company's first quarter of fiscal year 2015. Early adoption is permitted. The adoption of ASU No. 2013-11 in the first quarter of fiscal 2015 did not impact the Company's financial condition or results of operations.
	Standards to be Implemented
	Stock Compensation
	In June 2014, the FASB issued ASU No. 2014-12 (ASU 2014-12), Accounting for Share-Based Payments When the Terms of an Award Provide That a Performance Target Could Be Achieved after the Requisite Service Period, which requires that a performance target that affects vesting and that could be achieved after the requisite service period be treated as a performance condition. ASU 2014-12 is effective for annual periods and interim periods within those annual periods beginning after December 15, 2015, which is the Company’s first quarter of fiscal year 2017. Early adoption is permitted. The adoption of ASU 2014-12 in the first quarter of fiscal 2017 is not expected to have a material impact on the Company's financial condition or results of operations.
	Revenue Recognition
	In May 2014, the FASB issued ASU No. 2014-09 (ASU 2014-09), Revenue from Contracts with Customers, which supersedes nearly all existing revenue recognition guidance under U.S. GAAP. The core principle of ASU 2014-09 is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. Additionally, the guidance requires improved disclosures to help users of financial statements better understand the nature, amount, timing, and uncertainty of revenue and cash flows arising from contracts with customers. ASU 2014-09 is effective for annual reporting periods beginning after December 15, 2016, including interim periods within that reporting period, which is the Company’s first quarter of fiscal 2018. Early application is not permitted. The guidance allows for the amendment to be applied either retrospectively to each prior reporting period presented or retrospectively as a cumulative-effect adjustment as of the date of adoption. The Company is in the process of evaluating the impact of adoption on its consolidated financial statements.
	Discontinued Operations
	In April 2014, the FASB issued ASU No. 2014-08 (ASU 2014-08), Presentation of Financial Statements (Topic 205) and Property, Plant, and Equipment (Topic 360): Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity, which raises the threshold for disposals to qualify as discontinued operations. Under the new guidance, a disposal representing a strategic shift that has (or will have) a major effect on an entity’s financial results or a business activity classified as held for sale, should be reported as discontinued operations. ASU 2014-08 also expands the disclosure requirements for discontinued operations and adds new disclosures for individually significant dispositions that do not qualify as discontinued operations. ASU 2014-08 is effective prospectively for fiscal years, and interim reporting periods within those years, beginning after December 15, 2014, which is the Company's first quarter of fiscal year 2016. Early adoption is permitted, but only for disposals (or classifications as held for sale) that have not been reported in the financial statements previously issued or available for issuance. As of January 31, 2015, there have been no disposals or classifications as held for sale that would be subject to ASU 2014-08. As such, the Company will consider the adoption of this standard upon the earlier of a disposal or classification as held for sale.

Revenue Recognition [Abstract]
Revenue Recognition	Revenue Recognition
	Revenue from product sales to customers is generally recognized when title passes, which is upon shipment in the U.S. and for certain foreign countries. For other foreign countries, title passes subsequent to product shipment, ordinarily within a week of shipment. Accordingly, the Company defers the revenue recognized relating to these other foreign countries until title has passed. For multiple element arrangements, the Company allocates arrangement consideration among the elements based on the relative fair values of those elements as determined using vendor-specific objective evidence or third-party evidence. The Company uses its best estimate of selling price to allocate arrangement consideration between the deliverables in cases where neither vendor-specific objective evidence nor third-party evidence is available. A reserve for sales returns and allowances for customers is recorded based on historical experience or specific identification of an event necessitating a reserve.
	Revenue from contracts with the United States government, government prime contractors and some commercial customers is generally recorded on a percentage of completion basis using either units delivered or costs incurred as the measurement basis for progress towards completion. The output measure is used to measure results directly and is generally the best measure of progress toward completion in circumstances in which a reliable measure of output can be established. Estimated revenue in excess of amounts billed is reported as unbilled receivables. Contract accounting requires judgment in estimating costs and assumptions related to technical issues and delivery schedule. Contract costs include material, subcontract costs, labor and an allocation of indirect costs. The estimation of costs at completion of a contract is subject to numerous variables involving contract costs and estimates as to the length of time to complete the contract. Changes in contract performance, estimated gross margin, including the impact of final contract settlements, and estimated losses are recognized in the period in which the changes or losses are determined.
	In all regions of the world, the Company defers revenue and the related cost of sales on shipments to distributors until the distributors resell the products to their customers. As a result, the Company’s revenue fully reflects end customer purchases and is not impacted by distributor inventory levels. Sales to distributors are made under agreements that allow distributors to receive price-adjustment credits, as discussed below, and to return qualifying products for credit, as determined by the Company, in order to reduce the amounts of slow-moving, discontinued or obsolete product from their inventory. These agreements limit such returns to a certain percentage of the value of the Company’s shipments to that distributor during the prior quarter. In addition, distributors are allowed to return unsold products if the Company terminates the relationship with the distributor.
	Distributors are granted price-adjustment credits for sales to their customers when the distributor’s standard cost (i.e., the Company’s sales price to the distributor) does not provide the distributor with an appropriate margin on its sales to its customers. As distributors negotiate selling prices with their customers, the final sales price agreed upon with the customer will be influenced by many factors, including the particular product being sold, the quantity ordered, the particular customer, the geographic location of the distributor and the competitive landscape. As a result, the distributor may request and receive a price-adjustment credit from the Company to allow the distributor to earn an appropriate margin on the transaction.
	Distributors are also granted price-adjustment credits in the event of a price decrease subsequent to the date the product was shipped and billed to the distributor. Generally, the Company will provide a credit equal to the difference between the price paid by the distributor (less any prior credits on such products) and the new price for the product multiplied by the quantity of the specific product in the distributor’s inventory at the time of the price decrease.
	Given the uncertainties associated with the levels of price-adjustment credits to be granted to distributors, the sales price to the distributor is not fixed or determinable until the distributor resells the products to their customers. Therefore, the Company defers revenue recognition from sales to distributors until the distributors have sold the products to their customers.
	Title to the inventory transfers to the distributor at the time of shipment or delivery to the distributor, and payment from the distributor is due in accordance with the Company’s standard payment terms. These payment terms are not contingent upon the distributors’ sale of the products to their customers. Upon title transfer to distributors, inventory is reduced for the cost of goods shipped, the margin (sales less cost of sales) is recorded as “deferred income on shipments to distributors, net” and an account receivable is recorded. Shipping costs are charged to cost of sales as incurred.
	The deferred costs of sales to distributors have historically had very little risk of impairment due to the margins the Company earns on sales of its products and the relatively long life-cycle of the Company’s products. Product returns from distributors that are ultimately scrapped have historically been immaterial. In addition, price protection and price-adjustment credits granted to distributors historically have not exceeded the margins the Company earns on sales of its products. The Company continuously monitors the level and nature of product returns and is in frequent contact with the distributors to ensure reserves are established for all known material issues.
	As of January 31, 2015 and November 1, 2014, the Company had gross deferred revenue of $348.2 million and $349.7 million, respectively, and gross deferred cost of sales of $70.0 million and $71.3 million, respectively. Deferred income on shipments to distributors remained flat in the first three months of fiscal 2015 as distributor sales to end customers offset product shipments into the channel during the first quarter of fiscal 2015.
	The Company generally offers a twelve-month warranty for its products. The Company’s warranty policy provides for replacement of defective products. Specific accruals are recorded for known product warranty issues. Product warranty expenses during each of the three-month periods ended January 31, 2015 and February 1, 2014 were not material.

Stock-Based Compensation	Stock-Based Compensation
	Stock-based compensation is measured at the grant date based on the grant-date fair value of the awards ultimately expected to vest, and is recognized as an expense on a straight-line basis over the vesting period, which is generally five years for stock options and three years for restricted stock units. In addition to restricted stock units with a service condition, the Company grants restricted stock units with both a market condition and a service condition (market-based restricted stock units). The number of shares of the Company's common stock to be issued upon vesting of market-based restricted stock units will range from 0% to 200% of the target amount, based on the comparison of the Company's total shareholder return (TSR) to the median TSR of a specified peer group over a three-year period. TSR is a measure of stock price appreciation plus any dividends paid during the performance period. Determining the amount of stock-based compensation to be recorded for stock options and market-based restricted stock units requires the Company to develop estimates to calculate the grant-date fair value of awards.

Earnings Per Share [Abstract]
Earnings Per Share of Common Stock	Basic earnings per share is computed based only on the weighted average number of common shares outstanding during the period. Diluted earnings per share is computed using the weighted average number of common shares outstanding during the period, plus the dilutive effect of potential future issuances of common stock relating to stock option programs and other potentially dilutive securities using the treasury stock method. In calculating diluted earnings per share, the dilutive effect of stock options is computed using the average market price for the respective period. In addition, the assumed proceeds under the treasury stock method include the average unrecognized compensation expense of stock options that are in-the-money and restricted stock units. This results in the “assumed” buyback of additional shares, thereby reducing the dilutive impact of in-the-money stock options. Potential shares related to certain of the Company’s outstanding stock options were excluded because they were anti-dilutive. Those potential shares, determined based on the weighted average exercise prices during the respective periods, related to the Company’s outstanding stock options could be dilutive in the future.

Fair Value Disclosures [Abstract]
Fair Value	Fair Value
	The Company defines fair value as the price that would be received to sell an asset or be paid to transfer a liability in an orderly transaction between market participants at the measurement date. The Company applies the following fair value hierarchy, which prioritizes the inputs used to measure fair value into three levels and bases the categorization within the hierarchy upon the lowest level of input that is available and significant to the fair value measurement. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements).
	Level 1 — Level 1 inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities that the reporting entity has the ability to access at the measurement date.
	Level 2 — Level 2 inputs are inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly. If the asset or liability has a specified (contractual) term, a Level 2 input must be observable for substantially the full term of the asset or liability.
	Level 3 — Level 3 inputs are unobservable inputs for the asset or liability in which there is little, if any, market activity for the asset or liability at the measurement date.
	The tables below set forth by level the Company’s financial assets and liabilities, excluding accrued interest components, that are accounted for at fair value on a recurring basis as of January 31, 2015 and November 1, 2014. The tables exclude cash on hand and assets and liabilities that are measured at historical cost or any basis other than fair value. As of January 31, 2015 and November 1, 2014, the Company held $84.6 million and $121.3 million, respectively, of cash and held-to-maturity investments that were excluded from the tables below.

The following methods and assumptions were used by the Company in estimating its fair value disclosures for financial instruments:
Cash equivalents and short-term investments — These investments are adjusted to fair value based on quoted market prices or are determined using a yield curve model based on current market rates.
Deferred compensation plan investments — The fair value of these mutual fund, money market fund and equity investments are based on quoted market prices.
Forward foreign currency exchange contracts — The estimated fair value of forward foreign currency exchange contracts, which includes derivatives that are accounted for as cash flow hedges and those that are not designated as cash flow hedges, is based on the estimated amount the Company would receive if it sold these agreements at the reporting date taking into consideration current interest rates as well as the creditworthiness of the counterparty for assets and the Company’s creditworthiness for liabilities. The fair value of these instruments is based upon valuation models using current market information such as strike price, spot rate, maturity date and volatility.
Interest rate swap agreements — The fair value of interest rate swap agreements is based on the quoted market price for the same or similar financial instruments.
Contingent consideration — The fair value of the contingent consideration was estimated utilizing the income approach and is based upon significant inputs not observable in the market. The income approach is based on two steps. The first step involves a projection of the cash flows that is based on the Company’s estimates of the timing and probability of achieving the defined milestones. The second step involves converting the cash flows into a present value equivalent through discounting. The discount rate reflects the Baa costs of debt plus the relevant risk associated with the asset and the time value of money.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivatives, Policy [Policy Text Block]	Foreign Exchange Exposure Management — The Company enters into forward foreign currency exchange contracts to offset certain operational and balance sheet exposures from the impact of changes in foreign currency exchange rates. Such exposures result from the portion of the Company’s operations, assets and liabilities that are denominated in currencies other
	than the U.S. dollar, primarily the Euro; other significant exposures include the Philippine Peso, the Japanese Yen and the British Pound. These foreign currency exchange contracts are entered into to support transactions made in the normal course of business, and accordingly, are not speculative in nature. The contracts are for periods consistent with the terms of the underlying transactions, generally one year or less. Hedges related to anticipated transactions are designated and documented at the inception of the respective hedges as cash flow hedges and are evaluated for effectiveness monthly. Derivative instruments are employed to eliminate or minimize certain foreign currency exposures that can be confidently identified and quantified. As the terms of the contract and the underlying transaction are matched at inception, forward contract effectiveness is calculated by comparing the change in fair value of the contract to the change in the forward value of the anticipated transaction, with the effective portion of the gain or loss on the derivative reported as a component of accumulated OCI in shareholders’ equity and reclassified into earnings in the same period during which the hedged transaction affects earnings. Any residual change in fair value of the instruments, or ineffectiveness, is recognized immediately in other (income) expense. Additionally, the Company enters into forward foreign currency contracts that economically hedge the gains and losses generated by the re-measurement of certain recorded assets and liabilities in a non-functional currency. Changes in the fair value of these undesignated hedges are recognized in other (income) expense immediately as an offset to the changes in the fair value of the asset or liability being hedged. As of January 31, 2015 and November 1, 2014, the total notional amount of these undesignated hedges was $38.7 million and $45.2 million, respectively. The fair value of these undesignated hedges in the Company’s condensed consolidated balance sheets as of January 31, 2015 was $0.7 million and was immaterial as of November 1, 2014.
	Interest Rate Exposure Management — The Company's current and future debt may be subject to interest rate risk. The Company utilizes interest rate derivatives to alter interest rate exposure in an attempt to reduce the effects of these changes.
	On October 28, 2014, the Company entered into forward starting interest rate swap transactions to hedge its exposure to the variability in future cash flows due to changes in interest rates for debt issuances expected to occur in the future. Amounts reported in OCI related to these derivatives will be reclassified from OCI to earnings as interest expense is incurred on the forecasted hedged fixed-rate debt, adjusting interest expense to reflect the fixed-rate entered into by the forward starting swaps. These cash flow instruments hedge forecasted interest payments to be made through 2025. These forward starting swaps will be terminated on the day the hedged forecasted debt issuances occur, but no later than December 1, 2015, if the hedged forecasted debt issuances do not occur. The total notional value of these hedges as of January 31, 2015 and November 1, 2014 was $500.0 million. The fair value of these hedges was $38.1 million as of January 31, 2015 , included in accrued liabilities, and $1.7 million as of November 1, 2014, included in other assets, in the Company's condensed consolidated balance sheet.
	On April 24, 2013, the Company entered into a treasury rate lock agreement with Bank of America. This agreement allowed the Company to lock a 10-year US Treasury rate of 1.7845% through June 14, 2013 for its anticipated issuance of the 2023 Notes. The Company designated this agreement as a cash flow hedge. On June 3, 2013, the Company terminated the treasury rate lock simultaneously with the issuance of the 2023 Notes which resulted in a gain of approximately $11.0 million. This gain is being amortized into interest expense over the 10-year term of the 2023 Notes. See Note 5, Accumulated Other Comprehensive Income (Loss), for more information relating to the amortization of the treasury rate lock into interest expense.
	The market risk associated with the Company’s derivative instruments results from currency exchange rate or interest rate movements that are expected to offset the market risk of the underlying transactions, assets and liabilities being hedged. The counterparties to the agreements relating to the Company’s derivative instruments consist of a number of major international financial institutions with high credit ratings. Based on the credit ratings of the Company’s counterparties as of January 31, 2015, nonperformance is not perceived to be a significant risk. Furthermore, none of the Company’s derivatives are subject to collateral or other security arrangements and none contain provisions that are dependent on the Company’s credit ratings from any credit rating agency. While the contract or notional amounts of derivative financial instruments provide one measure of the volume of these transactions, they do not represent the amount of the Company’s exposure to credit risk. The amounts potentially subject to credit risk (arising from the possible inability of counterparties to meet the terms of their contracts) are generally limited to the amounts, if any, by which the counterparties’ obligations under the contracts exceed the obligations of the Company to the counterparties. As a result of the above considerations, the Company does not consider the risk of counterparty default to be significant.
	The Company records the fair value of its derivative financial instruments in its condensed consolidated financial statements in other current assets, other assets or accrued liabilities, depending on their net position, regardless of the purpose or intent for holding the derivative contract. Changes in the fair value of the derivative financial instruments are either recognized periodically in earnings or in shareholders’ equity as a component of OCI. Changes in the fair value of cash flow hedges are recorded in OCI and reclassified into earnings when the underlying contract matures. Changes in the fair values of derivatives not qualifying for hedge accounting or the ineffective portion of designated hedges are reported in earnings as they occur

Goodwill and Intangible Assets Disclosure [Abstract]
Intangibles-Goodwill and Other	Intangible Assets
	The Company reviews finite-lived intangible assets for impairment whenever events or changes in circumstances indicate that the carrying value of assets may not be recoverable. Recoverability of these assets is determined by comparison of their carrying value to future undiscounted cash flows the assets are expected to generate over their remaining economic lives. If such assets are considered to be impaired, the impairment to be recognized in earnings equals the amount by which the carrying value of the assets exceeds their fair value determined by either a quoted market price, if any, or a value determined by utilizing a discounted cash flow technique.
	Goodwill and Intangible Assets
	Goodwill
	The Company evaluates goodwill for impairment annually, as well as whenever events or changes in circumstances suggest that the carrying value of goodwill may not be recoverable. The Company tests goodwill for impairment at the reporting unit level (operating segment or one level below an operating segment) on an annual basis on the first day of the fourth quarter (on or about August 1) or more frequently if indicators of impairment exist. In the first quarter of 2015, the Company implemented organizational changes designed to accelerate the Company's growth by increasing the speed and impact of its technological innovation. The organizational changes combine the Company's market and technology teams to address the evolving needs of the markets and customers the Company serves. The Company performed an impairment analysis immediately prior to and subsequent to the reorganization and evaluated goodwill for impairment as of the date of reorganization. The Company identified its reporting units to be its six operating segments. The performance of the test involves a two-step process. The first step of the impairment test involves comparing the fair values of the applicable reporting units with their aggregate carrying values, including goodwill. The Company determines the fair value of its reporting units using the income approach methodology of valuation that includes the discounted cash flow method, as well as other generally accepted valuation methodologies. If the carrying amount of a reporting unit exceeds the reporting unit’s fair value, the Company performs the second step of the goodwill impairment test to determine the amount of impairment loss. The second step of the goodwill impairment test involves comparing the implied fair value of the affected reporting unit with the carrying value of that reporting unit. Based on this analysis, no impairment was identified. The Company's next annual impairment assessment will be performed as of the first day of the fourth quarter of fiscal 2015 unless indicators arise that would require the Company to re-evaluate at an earlier date.
	Indefinite-lived intangible assets are tested for impairment on an annual basis on the first day of the fourth quarter (on or about August 1) or more frequently if indicators of impairment exist. The impairment test involves the comparison of the fair values of the intangible assets with their carrying amount. No impairment of intangible assets resulted from the impairment tests in any of the fiscal years presented.
	Intangible assets, excluding in-process research and development (IPR&D), are amortized on a straight-line basis over their estimated useful lives or on an accelerated method of amortization that is expected to reflect the estimated pattern of economic use. IPR&D assets are considered indefinite-lived intangible assets until completion or abandonment of the associated research and development (R&D) efforts. Upon completion of the projects, the IPR&D assets will be amortized over their estimated useful lives.

Inventory Disclosure [Abstract]
Inventory, Policy [Policy Text Block]	Inventories are valued at the lower of cost (first-in, first-out method) or market. The valuation of inventory requires the Company to estimate obsolete or excess inventory as well as inventory that is not of saleable quality. The Company employs a variety of methodologies to determine the net realizable value of its inventory. While a portion of the calculation to record inventory at its net realizable value is based on the age of the inventory and lower of cost or market calculations, a key factor in estimating obsolete or excess inventory requires the Company to estimate the future demand for its products. If actual demand is less than the Company’s estimates, impairment charges, which are recorded to cost of sales, may need to be recorded in future periods. Inventory in excess of saleable amounts is not valued, and the remaining inventory is valued at the lower of cost or market. Approximately $8.8 million of raw materials have been classified as non-current and are presented within the condensed consolidated balance sheet as other assets as the Company does not expect this inventory to be sold within one year. This inventory was purchased as part of a planned transition from a principal foundry supplier and was acquired by the Company through the Acquisition. The larger than normal purchase was made to maintain an adequate supply of the raw material for customers, which has a natural life of five to ten years.

	The Company has provided for potential tax liabilities due in the various jurisdictions in which the Company operates. Judgment is required in determining the worldwide income tax expense provision. In the ordinary course of global business, there are many transactions and calculations where the ultimate tax outcome is uncertain. Some of these uncertainties arise as a consequence of cost reimbursement arrangements among related entities. Although the Company believes its estimates are reasonable, no assurance can be given that the final tax outcome of these matters will not be different from that which is reflected in the historical income tax provisions and accruals. Such differences could have a material impact on the Company’s income tax provision and operating results in the period in which such determination is made.

	In July 2013, the Financial Accounting Standards Board (FASB) issued ASU No. 2013-11 (ASU No. 2013-11), Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists . ASU No. 2013-11 requires that an unrecognized tax benefit, or a portion of an unrecognized tax benefit, should be presented as a reduction to a deferred tax asset for a net operating loss carryforward, a similar tax loss or a tax credit carryforward, with certain exceptions. ASU No. 2013-11 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2013, which is the Company's first quarter of fiscal year 2015. Early adoption is permitted. The adoption of ASU No. 2013-11 in the first quarter of fiscal 2015 did not impact the Company's financial condition or results of operations.
	Standards to be Implemented
	Stock Compensation
	In June 2014, the FASB issued ASU No. 2014-12 (ASU 2014-12), Accounting for Share-Based Payments When the Terms of an Award Provide That a Performance Target Could Be Achieved after the Requisite Service Period, which requires that a performance target that affects vesting and that could be achieved after the requisite service period be treated as a performance condition. ASU 2014-12 is effective for annual periods and interim periods within those annual periods beginning after December 15, 2015, which is the Company’s first quarter of fiscal year 2017. Early adoption is permitted. The adoption of ASU 2014-12 in the first quarter of fiscal 2017 is not expected to have a material impact on the Company's financial condition or results of operations.
	Revenue Recognition
	In May 2014, the FASB issued ASU No. 2014-09 (ASU 2014-09), Revenue from Contracts with Customers, which supersedes nearly all existing revenue recognition guidance under U.S. GAAP. The core principle of ASU 2014-09 is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. Additionally, the guidance requires improved disclosures to help users of financial statements better understand the nature, amount, timing, and uncertainty of revenue and cash flows arising from contracts with customers. ASU 2014-09 is effective for annual reporting periods beginning after December 15, 2016, including interim periods within that reporting period, which is the Company’s first quarter of fiscal 2018. Early application is not permitted. The guidance allows for the amendment to be applied either retrospectively to each prior reporting period presented or retrospectively as a cumulative-effect adjustment as of the date of adoption. The Company is in the process of evaluating the impact of adoption on its consolidated financial statements.
	Discontinued Operations
	In April 2014, the FASB issued ASU No. 2014-08 (ASU 2014-08), Presentation of Financial Statements (Topic 205) and Property, Plant, and Equipment (Topic 360): Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity, which raises the threshold for disposals to qualify as discontinued operations. Under the new guidance, a disposal representing a strategic shift that has (or will have) a major effect on an entity’s financial results or a business activity classified as held for sale, should be reported as discontinued operations. ASU 2014-08 also expands the disclosure requirements for discontinued operations and adds new disclosures for individually significant dispositions that do not qualify as discontinued operations. ASU 2014-08 is effective prospectively for fiscal years, and interim reporting periods within those years, beginning after December 15, 2014, which is the Company's first quarter of fiscal year 2016. Early adoption is permitted, but only for disposals (or classifications as held for sale) that have not been reported in the financial statements previously issued or available for issuance. As of January 31, 2015, there have been no disposals or classifications as held for sale that would be subject to ASU 2014-08. As such, the Company will consider the adoption of this standard upon the earlier of a disposal or classification as held for sale.

	The Company utilizes the Monte Carlo simulation valuation model to value market-based restricted stock units. The Monte Carlo simulation model utilizes multiple input variables that determine the probability of satisfying the performance conditions stipulated in the award grant and calculates the fair market value for the market-based restricted stock units granted. The Monte Carlo simulation model also uses stock price volatility and other variables to estimate the probability of satisfying the performance conditions, including the possibility that the market condition may not be satisfied, and the resulting fair value of the award. Market-based restricted stock units were not granted during the three-month periods ended January 31, 2015 or February 1, 2014.

Segment Reporting [Abstract]
Revenue Trends by End Market	Revenue Trends by End Market
	The following table summarizes revenue by end market. The categorization of revenue by end market is determined using a variety of data points including the technical characteristics of the product, the “sold to” customer information, the “ship to” customer information and the end customer product or application into which the Company’s product will be incorporated. As data systems for capturing and tracking this data evolve and improve, the categorization of products by end market can vary over time. When this occurs, the Company reclassifies revenue by end market for prior periods. Such reclassifications typically do not materially change the sizing of, or the underlying trends of results within, each end market.
