Basis of Presentation	'
	Basis of Presentation
	Interim financial statements and information are unaudited; however, in the opinion of management, all adjustments necessary for a fair and accurate presentation of the interim results in conformity with U.S. generally accepted accounting principles (“GAAP”) have been made.  All such adjustments were of a normal recurring nature.  The results for the three and nine-month periods ended March 30, 2014 are not necessarily an indication of results to be expected for the entire fiscal year.  All information reported in this Form 10-Q should be read in conjunction with the Company’s annual consolidated financial statements for the fiscal year ended June 30, 2013 included in the Company’s Annual Report on Form 10-K.  The accompanying balance sheet at June 30, 2013 has been derived from those audited financial statements.  Because the Company is viewed as a single operating segment for management purposes, no segment information has been disclosed.
	Revenue Recognition
	The Company recognizes revenues when the earnings process is complete, when persuasive evidence of an arrangement exists, the product has been delivered, the price is fixed and determinable and collection is reasonably assured.  During both the third quarter and the first nine months of fiscal year 2014, the Company recognized approximately 15% of net revenues from domestic distributors that are recognized under agreements which provide for certain sales price rebates and limited product return privileges.  Given the uncertainties associated with the levels of pricing rebates, the ultimate sales price on domestic distributor revenue transactions is not fixed or determinable until domestic distributors sell the merchandise to the end-customer.  At the time of shipment to domestic distributors, the Company records a trade receivable and deferred revenue at the distributor purchasing price since there is a legally enforceable obligation from the distributor to pay for the products delivered.  The Company relieves inventory as title has passed to the distributor and recognizes deferred cost of sales in the same amount. “Deferred income on shipments to distributors” represents the difference between deferred revenue and deferred cost of sales and is recognized as a current liability until such time as the distributor confirms a final sale to its end customer.  At March 30, 2014, the Company had approximately $53.6 million of deferred revenue and $10.4 million of deferred cost of sales recognized as $43.2 million of “Deferred income on shipments to distributors.”  The Company believes that its deferred costs of revenues have limited risk of material impairment as the Company offers stock rotation privileges to distributors (up to 3% to 5% of quarterly purchases) which enable distributors to rotate slow moving inventory. In addition, stock rotated inventory that is returned to the Company is generally resalable.  The Company reviews distributor ending on-hand inventory balances, as well as orders placed on the Company to ensure that distributors are not overstocking parts and are ordering to forecasted demand. To the extent the Company had a significant reduction in distributor price or grants significant price rebates, there could be a material impact on the ultimate revenue and gross profit recognized. The price rebates that have been remitted back to distributors have generally ranged from $2.7 million to $3.7 million per quarter.
	The Company’s sales to international distributors are made under agreements which permit limited stock return privileges but not sales price rebates.  Revenue on these sales is recognized upon shipment at which time title passes.  The Company has reserves to cover expected product returns.  If product returns for a particular fiscal period exceed or are below expectations, the Company may determine that additional or less sales return allowances are required to properly reflect its estimated exposure for product returns.  Generally, changes to sales return allowances have not had a significant impact on operating margin.

	Earnings Per Share
	Basic earnings per share is calculated using the weighted average shares of common stock and unvested restricted stock outstanding during the period.  Diluted earnings per share is calculated using the weighted average shares of common stock outstanding, the dilutive effect of stock options using the treasury stock method and the dilutive effect of the conversion premium related to the convertible senior notes.  The following table sets forth the reconciliation of weighted average common shares outstanding used in the computation of basic and diluted earnings per share:

	Diluted earnings per share	$	0.48	$	0.46	$	1.37	$	1.28
	For the quarter and the nine months ended March 30, 2014, there were no out-of-the-money stock options that had to be excluded from the weighted average diluted common shares outstanding. The weighted average diluted common shares outstanding for the quarter and the nine months ended March 31, 2013 excludes the effect of 2.6 million and 4.7 million, respectively, out-of-the-money stock options, that if included would be anti-dilutive.
	The Company included the dilutive effect of the conversion premium related to the convertible senior notes in the calculation of diluted earnings per common share because the average per share market price of the Company's common stock was above the conversion price during the quarter and the nine months ended March 30, 2014. The conversion premium was not included in the calculation of diluted earnings per common share in the prior year periods because the average per share market prices were below the conversion prices during these periods.

Fair Value Disclosures [Abstract]	'
Fair Value	'
	Fair Value
	The Company has determined that the only assets and liabilities in the Company’s financial statements that are required to be measured at fair value on a recurring basis are the Company’s investment portfolio assets.  Financial instruments are categorized in a fair value hierarchy that prioritizes the information used to develop assumptions for measuring fair value and expands disclosures about fair value measurements. The fair value hierarchy gives the highest priority to quoted prices in active markets for identical assets or liabilities (Level 1 input); then to quoted prices (in non-active markets or in active markets for similar assets or liabilities), inputs other than quoted prices that are observable for the asset or liability, and inputs that are not directly observable, but that are corroborated by observable market data for the asset or liability (Level 2 input); then the lowest priority to unobservable inputs, for example, the Company’s data about the assumptions that market participants would use in pricing an asset or liability (Level 3 input). Fair value is a market-based measurement, not an entity-specific measurement, and a fair value measurement should therefore be based on the assumptions that market participants would use in pricing the asset or liability.
	The Company’s Level 1 assets consist of investments in money-market funds and United States Treasury securities that are actively traded.  The Company’s Level 2 assets consist of municipal bonds, obligations of U.S. government-sponsored enterprises, corporate debt and commercial paper that are less actively traded in the market, but where quoted market prices exist for similar instruments that are actively traded. The Company determines the fair value of its Level 2 assets by obtaining non-binding market prices from its third-party portfolio managers on the last day of the quarter. The Company has no Level 3 assets.
	The following table presents the Company’s fair value hierarchy for its financial assets (cash equivalents and marketable securities) measured at fair value on a recurring basis as of March 30, 2014:

	(1) The Company evaluated the nature of the investments with a loss position at March 30, 2014 and June 30, 2013, which are primarily obligations of the U.S. government and its sponsored enterprises, municipal bonds and U.S. corporate notes.  In evaluating the investments, the Company considered the duration of the impairments, and the amount of the impairments relative to the underlying portfolio and concluded that such amounts were not other-than-temporary. The Company principally holds securities until maturity, however, they may be sold under certain circumstances.  Unrealized losses on the investments greater than twelve months old were not significant as of March 30, 2014 and June 30, 2013.
	The estimated fair value of debt investments in marketable securities, by effective maturity date is as follows:

	Stock-based Compensation
	Equity Incentive Plans
	At March 30, 2014, 18.7 million shares were available for grant under the Company’s equity incentive plans.  The Company’s restricted awards generally vest annually over a period of five years (20% a year) based upon continued employment with the Company.  Options also generally become exercisable over a five-year period (generally 10% every six months) based upon continued employment.  Options granted prior to January 11, 2005 expire ten years after the date of grant; options granted after January 11, 2005 expire seven years after the date of the grant. The Company's last stock option grant to an employee was in January 2010.
	The Company has an Employee Stock Purchase Plan (“ESPP”) that permits eligible employees to purchase common stock through payroll deductions at 85% of the fair market value of the common stock at the end of each six-month offering period.  The offering periods generally commence on approximately May 1 and November 1 of each year.  At March 30, 2014, 0.9 million shares were available for issuance under the ESPP.
	Accounting for Stock-Based Compensation
	Compensation cost for restricted stock awards is based on the fair market value of the Company’s stock on the date of grant.  Compensation cost for stock options is calculated on the date of grant using the fair value of stock options as determined using the Black-Scholes valuation model.  The Company amortizes the compensation cost straight-line over the vesting period, which is generally five years.  The Black-Scholes valuation model requires the Company to estimate key assumptions such as expected option term, stock price volatility and forfeiture rates to determine the fair value of a stock option. The estimate of these key assumptions is based on historical information and judgment regarding market factors and trends.
	As of March 30, 2014, there was approximately $172.4 million of total unrecognized stock-based compensation cost related to share-based payments granted under the Company’s stock-based compensation plans that will be recognized over a period of approximately 5 years.  Future grants will add to this total, whereas quarterly amortization and the vesting of the existing grants will reduce this total.
	The Company issues new shares of common stock upon exercise of stock options. For the nine months ended March 30, 2014, options for approximately 2.8 million shares were exercised for a gain to the optionee (aggregate intrinsic value) of $34.7 million determined as of the dates of the option exercises.

	Goodwill and Intangible Assets
	Goodwill
	The Company annually evaluates goodwill for impairment as well as whenever events or changes in circumstances might suggest that the carrying value of goodwill may not be recoverable. The Company expects that none of the goodwill will be deductible for tax purposes. The goodwill balance of $2.2 million at March 30, 2014 is attributable to the acquisition of Dust Networks ("Dust") in fiscal year 2012. There were no changes to the goodwill balance for the quarter ended March 30, 2014.
	Intangible Assets
	As a result of the acquisition of Dust during the second quarter of fiscal year 2012 the Company recorded intangible assets consisting of $13.1 million of intellectual property and $4.0 million of customer relationships. The Company reviews intangible assets for impairment whenever events or changes in circumstances indicate that the carrying value of assets may not be recoverable. Finite-intangible assets are amortized on a straight-line basis over their estimated useful lives that are expected to reflect the estimated pattern of economic use.
	The remaining amortization expense, related to finite-intangible assets, will be recognized over a weighted-average period of approximately 6.6 years.  The useful lives of amortizable intangible assets are as follows:
	Assets	Life
	Intellectual property	5-10 years
	Customer relationships	10 years

	Convertible Senior Notes
	During the fourth quarter of fiscal year 2007, the Company issued $1.0 billion aggregate principal amount of its 3.00% Convertible Senior Notes due May 1, 2027 (the “2027A notes”) and $700.0 million aggregate principal amount of its 3.125% Convertible Senior Notes due May 1, 2027 (the “2027B notes” and, together with the 2027A notes, the “Notes”) to an initial purchaser in a private offering.  The Company received net proceeds from the issuance of the Notes of $1,678.0 million after the deduction of issuance costs of $22.0 million.  The Company used the entire net proceeds of the offering to fund a portion of its repurchase of $3.0 billion of its common stock pursuant to an accelerated stock repurchase transaction it entered into with an affiliate of the initial purchaser of the Notes simultaneously with the offering of the Notes.  The Company redeemed for cash $395.8 million (the remaining principal amount) of its 2027B notes on November 1, 2010 using a portion of its existing cash and marketable securities balances.  Through the third quarter of fiscal year 2014 the Company has repurchased $154.9 million (principal amount) of its 2027A notes, resulting in approximately $845.1 million (principal amount) of debt outstanding as of March 30, 2014. During the third quarter and the first nine months of fiscal year 2014, 2,422 thousand shares and 819 thousand shares, respectively, related to the Notes were included in the computation of diluted earnings per share.
	At March 30, 2014, the conversion rate of the 2027A notes was 24.582 shares of common stock per $1,000 principal amount of the 2027A notes, subject to adjustment upon the occurrence of certain events as described in the Indenture for the 2027A notes (including the payment of dividends). On May 1, 2014, the Company redeemed all of the 2027A notes. For further information on the redemption see Note 15 of Notes to Consolidated Financial Statements.
	The 2027A notes pay cash interest of 3.00% which is payable semiannually in arrears on May 1 and November 1.  In accordance with the provisions of ASC 470-20-10 to 35 the Company recognizes an effective interest rate of 5.69% on the carrying value of the 2027A notes. The effective rate is based on the interest rates of similar instruments issued at the time of issuance of the Notes that do not have conversion features such as the Notes. The differences between the effective interest rates of 5.69% and the coupon rate of 3.00%, results in non-cash interest expense that will never be paid by the Company. All interest costs related to the Notes were terminated when the Notes were redeemed on May 1, 2014.

	Stock Repurchase
	On October 16, 2012, the Company’s Board of Directors authorized the Company to purchase up to 10.0 million shares of its outstanding common stock in the open market over a two-year time period. During the quarter ended March 30, 2014, the Company repurchased approximately 0.2 million shares of its common stock for approximately $10.9 million. As of March 30, 2014, the Company had remaining authorization to repurchase up to an additional 7.6 million shares of the Company's common stock.
	In addition to open market repurchases, the Company also repurchases shares related to equity award vestings as outlined below. During the quarter ended March 30, 2014, the Company repurchased approximately 171.3 thousand shares related to equity grants of its common stock for approximately $7.8 million. The Company generally grants restricted stock awards and restricted stock units under its equity incentive plans, which are subject to vesting. Recipients are required to pay tax on such awards and units at the time they vest. For the majority of restricted stock awards and units granted, the number of shares issued on the date the awards and units vest is net of the minimum statutory withholding requirements that the Company pays in cash to the appropriate taxing authorities on behalf of its employees. These withheld shares are not included in the open market common stock repurchase totals in the above paragraph even though they are treated as common stock repurchases in our financial statements, as they reduce the number of shares that would otherwise have been issued.
	Dividends
	In April 2014, the Company's Board of Directors approved a cash dividend of $0.27 per share to be paid on May 28, 2014 to stockholders of record on May 16, 2014. During the nine months ended March 30, 2014, the Company paid $189.2 million in dividends representing $0.79 per share. The payment of future dividends will be based on the Company's financial performance.
	During the quarter ended December 30, 2012, the Company's Board of Directors accelerated the payment of its March quarterly dividend payment into the December quarter to benefit shareholders due to increases in tax rates on investment income in the United States.

	Product Warranty and Indemnification
	The Company’s warranty policy provides for the replacement of defective parts.  In certain large contracts, the Company has agreed to negotiate in good faith a product warranty in the event that an epidemic failure of its parts was to take place. To date there have been no significant occurrences.  Warranty expense historically has been negligible.
	The Company provides a limited indemnification for certain customers against intellectual property infringement claims related to the Company's products. In certain cases, there are limits on and exceptions to the Company's potential liability for indemnification relating to intellectual property infringement claims.  To date, the Company has not incurred any significant indemnification expenses relating to intellectual property infringement claims.  The Company cannot estimate the amount of potential future payments, if any, that it might be required to make as a result of these agreements, and accordingly, the Company has not accrued any amounts for its indemnification obligations.

	Income Taxes
	The Company must recognize the tax benefit from an uncertain tax position only if it is more likely than not that the tax position will be sustained on examination by the taxing authorities, based on the technical merits of the position. The tax benefits recognized in the financial statements from such a position are measured based on the largest benefit that has a greater than fifty percent likelihood of being realized upon ultimate resolution. As of March 30, 2014, the Company's other long-term liabilities account includes $31.7 million of unrecognized tax benefits of which approximately $15.3 million would favorably impact its effective income tax rate in future periods if the Company's positions on these tax matters are upheld.  The Company's policy is to recognize interest and/or penalties related to income tax matters in income tax expense. Included in the liability for unrecognized tax benefits was $2.5 million accrued for interest at March 30, 2014.
	The Company's effective income tax rates for the third quarter and the first nine months of fiscal year 2014 were 21.00% and 23.79%, respectively, as compared to 12.75% and 22.39%, respectively, in the same periods of fiscal year 2013.  The increase in the effective income tax rates from the prior year periods was primarily due to the reinstatement during the third quarter of fiscal 2013 of the Federal Research and Development Tax Credit (“R&D Tax Credit”) that had expired December 31, 2011. As a result of reinstatement, during the third quarter of fiscal 2013 the Company adjusted its effective income tax rate for a full year’s R&D Tax Credit and recorded a discrete tax benefit for the prior fiscal year 2012 R&D Tax Credit. The R&D Tax Credit legislation expired once again effective December 31, 2013. Accordingly, the annual effective tax rate for fiscal 2014 includes the benefit of the R&D Tax Credit for six months whereas fiscal year 2013 included a full year’s tax benefit. In addition, the effective tax rates for each of the quarterly periods were favorably impacted by certain discrete tax benefits, primarily from the release of unrecognized tax benefits attributable to tax periods no longer subject to audit. The release of these tax benefits in fiscal 2013 had a greater impact on the effective tax rate recognized for the fiscal third quarter of 2013 as compared to the same period of fiscal 2014.

	Revenue Recognition
	The Company recognizes revenues when the earnings process is complete, when persuasive evidence of an arrangement exists, the product has been delivered, the price is fixed and determinable and collection is reasonably assured.  During both the third quarter and the first nine months of fiscal year 2014, the Company recognized approximately 15% of net revenues from domestic distributors that are recognized under agreements which provide for certain sales price rebates and limited product return privileges.  Given the uncertainties associated with the levels of pricing rebates, the ultimate sales price on domestic distributor revenue transactions is not fixed or determinable until domestic distributors sell the merchandise to the end-customer.  At the time of shipment to domestic distributors, the Company records a trade receivable and deferred revenue at the distributor purchasing price since there is a legally enforceable obligation from the distributor to pay for the products delivered.  The Company relieves inventory as title has passed to the distributor and recognizes deferred cost of sales in the same amount. “Deferred income on shipments to distributors” represents the difference between deferred revenue and deferred cost of sales and is recognized as a current liability until such time as the distributor confirms a final sale to its end customer.  At March 30, 2014, the Company had approximately $53.6 million of deferred revenue and $10.4 million of deferred cost of sales recognized as $43.2 million of “Deferred income on shipments to distributors.”  The Company believes that its deferred costs of revenues have limited risk of material impairment as the Company offers stock rotation privileges to distributors (up to 3% to 5% of quarterly purchases) which enable distributors to rotate slow moving inventory. In addition, stock rotated inventory that is returned to the Company is generally resalable.  The Company reviews distributor ending on-hand inventory balances, as well as orders placed on the Company to ensure that distributors are not overstocking parts and are ordering to forecasted demand. To the extent the Company had a significant reduction in distributor price or grants significant price rebates, there could be a material impact on the ultimate revenue and gross profit recognized. The price rebates that have been remitted back to distributors have generally ranged from $2.7 million to $3.7 million per quarter.
	The Company’s sales to international distributors are made under agreements which permit limited stock return privileges but not sales price rebates.  Revenue on these sales is recognized upon shipment at which time title passes.  The Company has reserves to cover expected product returns.  If product returns for a particular fiscal period exceed or are below expectations, the Company may determine that additional or less sales return allowances are required to properly reflect its estimated exposure for product returns.  Generally, changes to sales return allowances have not had a significant impact on operating margin.

[1]	The Company evaluated the nature of the investments with a loss position at MarchB 30, 2014 and JuneB 30, 2013, which are primarily obligations of the U.S. government and its sponsored enterprises, municipal bonds and U.S. corporate notes. In evaluating the investments, the Company considered the duration of the impairments, and the amount of the impairments relative to the underlying portfolio and concluded that such amounts were not other-than-temporary. The Company principally holds securities until maturity, however, they may be sold under certain circumstances. Unrealized losses on the investments greater than twelve months old were not significant as of MarchB 30, 2014 and JuneB 30, 2013.
