    SANTA CLARA, Calif.--(BUSINESS WIRE)--Oct. 16, 2003--

         Company Reports ($0.01) Pro-Forma EPS, $0.01 GAAP EPS

    IDT(TM) (Integrated Device Technology, Inc.)(Nasdaq:IDTI), a
leading communications IC company, today announced results for the
quarter ended September 28, 2003, its second quarter of fiscal 2004.
    Revenues for the second fiscal quarter were $80.8 million, a
decrease of 2.7 percent compared to the first quarter of fiscal 2004
and a decrease of 12.4 percent from the quarter ended September 29,
2002. On a pro-forma basis, the net loss for the second fiscal quarter
was $1.1 million ($0.01 per diluted share), compared to a net loss of
$4.8 million ($0.05 per diluted share) in the first quarter of fiscal
2004 and net income of $1.0 million or $0.01 per diluted share for the
quarter one year ago.
    Including certain costs, charges and gains in accordance with
GAAP, the Company earned net income of $1.2 million in the second
quarter of fiscal 2004 ($0.01 per diluted share), compared to a loss
of $4.8 million ($0.05 per diluted share) in the first quarter of
fiscal 2004. On a GAAP basis, the Company recorded a net loss of $4.9
million ($0.05 per diluted share) for the second quarter of fiscal
2003. Further information, including a detailed reconciliation of
pro-forma and GAAP results, is provided in the financial tables of
this release.
    "For the third consecutive quarter, we experienced strong
sequential growth in the enterprise market. This growth is fueled by
the demand for high-quality packet-processing products for IP
networks," said Greg Lang, president and CEO of IDT. "We are also
seeing encouraging signs of future growth in most of our market
segments. Our customers' outlooks are more positive, inventories are
under control while supplies are tightening, and average selling
prices are stabilizing."

    Q2FY04 Highlights:

    --  IDT announced an agreement with IBM to purchase its
        full-ternary network search engine (NSE) product designs
        targeted at the enterprise switching market. With the
        acquisition, IDT further extended its leadership by offering
        the broadest and deepest portfolio of NSE solutions that
        accelerate packet processing. Specific to the transaction, IDT
        acquired 128Kx36 (4.5-Mbit) and 512Kx36 (18-Mbit) product
        designs, and IBM will serve as the foundry to manufacture
        these NSEs using a 0.13-micron, copper process.

    --  Leveraging its expertise in providing clock-distribution and
        clock-generation solutions, IDT entered the PC clock market
        with a family of devices targeting desktop computing
        platforms. The new devices are based on a new four
        phase-locked-loop (PLL) PC clock architecture that enables
        complete, independent control of key clock circuits within the
        system, replacing traditional three-PLL clock architectures.
        IDT plans to expand its offerings and develop a suite of PC
        clock devices that serve next-generation notebook and desktop
        computing platforms.

    --  IDT expanded its portfolio of Interprise(TM) processors with
        the introduction of the RC32336 integrated communications
        processor. The RC32336 processor delivers performance up to
        180 MHz and is targeted at the cost-sensitive, high-volume
        small and medium enterprise (SME) and small office/home office
        (SOHO) wireless gateways, and wireless access point markets.
        Additionally, the RC32336 processor provides increased
        functionality and integration, allowing for connectivity to a
        wide range of networking devices including wireless local area
        network (WLAN) chipsets, and enables system developers to
        design fully featured and cost-effective solutions at a
        competitive price/performance point.

    --  The Company introduced a new family of inverse multiplexing
        ATM (IMA) devices that offer specific features for remote
        equipment such as mobile base stations and DSL multiplexers.
        The IMA devices allow the remote configuration of up to eight
        IMA groups at a far-end unit via the IMA group auto-detect
        function. The devices offer the most advanced user interface
        in the industry, simplifying software development, reducing
        costs and speeding time to market. The IDT IMA devices,
        coupled with the Company's SuperJET(TM) transceivers, provide
        a complete solution for IMA line-card applications, with the
        industry's lowest power consumption, chip count and board
        space.
