                      MAXIM TO ACQUIRE DALLAS SEMICONDUCTOR
                     FOR APPROXIMATELY $2.5 BILLION IN STOCK

       SUNNYVALE, CA and DALLAS, TX -January 29, 2001- Maxim Integrated
Products, Inc. (Nasdaq: MXIM), and Dallas Semiconductor Corporation (NYSE: DS),
today announced an agreement under which Maxim will acquire Dallas
Semiconductor, a leading provider of specialty semiconductors. Based on Maxim's
closing price on Friday, January 26, 2001, each outstanding share of Dallas
Semiconductor would be exchanged for 0.6163 of a share of Maxim, and Maxim would
issue approximately $2.5 billion of stock for all of the outstanding shares and
stock options of Dallas Semiconductor. Under the agreement, the actual exchange
ratio will be determined by a formula that is described below. This acquisition
is anticipated to be completed during the second quarter of calendar 2001 and is
subject to approval by Dallas Semiconductor's stockholders and compliance with
applicable regulatory requirements. In addition, this transaction is intended to
be accounted for as a pooling-of-interests and to qualify as a tax-free
reorganization. Because of this, Maxim will be rescinding its existing common
stock repurchase program prior


                                     -more-

to consummation of the transaction. Excluding one-time acquisition-related
expenses, Maxim expects the acquisition to be slightly accretive in its fiscal
2001 results.

       "The synergy and growth opportunity of combining our organizations and
product lines was apparent to both sides from the start of our discussions,"
said Jack Gifford, Chairman, President, and Chief Executive Officer of Maxim.
"Dallas Semiconductor has many product lines that are complementary to Maxim's,
and we look forward to giving more visibility to Dallas Semiconductor's
excellent digital and mixed-signal circuits in both the domestic and the
international marketplaces." Mr. Gifford added, "We believe that the cultures of
the two companies are closely aligned in their focus on product proliferation
and engineering innovation. Dallas Semiconductor has an extremely talented group
of professionals, and there is no plan for a workforce reduction."

       Dr. Chao C. Mai, President and Chief Operating Officer of Dallas
Semiconductor, commented: "We are excited about this transaction. After careful
deliberation, emphasizing leadership, engineering, culture, and product line
fit, we chose Maxim as the right partner. We share Maxim's strategic vision of
the market and customer needs. We believe that Maxim's worldwide selling,
applications, and marketing strengths should further enhance Dallas
Semiconductor's revenue growth and gross margins."

       The exchange ratio will be determined by dividing a number of Maxim share
equivalents by the number of outstanding Dallas Semiconductor share equivalents
at closing (calculated using the treasury method). The number of Maxim share
equivalents will range linearly from 40 million share equivalents (if Maxim's
average closing price during a 10-day trading period ending two days prior to
closing is $61 per share or more) to 42 million share equivalents (if Maxim's
average closing price during the relevant trading period is $52 or less).
