    DESCRIPTION:
    The IDT71256 is a 262,144-bit high-speed static RAM
    organized as 32K x 8. It is fabricated using IDT’s high-
    performance, high-reliability CMOS technology.
    Address access times as fast as 20ns are available with
    power consumption of only 350mW (typ.). The circuit also
    offers a reduced power standby mode. When
    CS
    goes HIGH,
    the circuit will automatically go to, and remain in, a low-power
    standby mode as long as
    CS
    remains HIGH. In the full standby
    mode, the low-power device consumes less than 15
    μ
    W,
    typically. This capability provides significant system level
    power and cooling savings. The low-power (L) version also
    offers a battery backup data retention capability where the
    circuit typically consumes only 5
    μ
    W when operating off a 2V
    battery.
    The lDT71256 is packaged in a 28-pin (300 or 600 mil)
    ceramic DIP, a 28-pin 300 mil J-bend SOlC, and a 28-pin (600
    mil) plastic DIP, and 32-pin LCC providing high board-level
    packing densities.
    The IDT71256 military RAM is manufactured in compliance
    with the latest revision of MIL-STD-883, Class B, making it
    ideally suited to military temperature applications demanding
    the highest level of performance and reliability.
