July 6, 2005

SAN JOSE, Calif., July 6, 2005  IDT (Integrated Device Technology, Inc.; NASDAQ:  IDTI), a leading communications IC Company, today announced that it has reduced its revenue outlook for the first quarter of fiscal 2006 ending July 3, 2005.  Based on recent shipment trends to customers, IDT now projects revenue to be down approximately 3 to 4 percent from the immediate preceding quarter’s revenue of $97.1 million.  Previously, the Company estimated revenues for the quarter to be flat to up 4 percent relative to the prior quarter.

The lower revenue forecast is a result of a combination of factors, including general weakness across most end markets other than Enterprise, as well as unanticipated softness in distribution revenue.
IDT is scheduled to report its first quarter fiscal 2006 results during a Webcast and conference call taking place on July 28, 2005 at 1:30 p.m. PDT.  The Webcast will be accessible via the Investor Relations page located at www.IDT.com.
