a very low standby power mode.
FabricatedusingIDT’sCMOShigh-performancetechnology,these
devices typically operate on only 325mW of power. Low-power (LA)
versionsofferbatterybackupdataretentioncapability,witheachDual-
Port typically consuming 200µW from a 2V battery.
The IDT7132/7142 devices are packaged in a 48-pin sidebraze or
plastic DIPs, 48-pin LCCs, 52-pin PLCCs, and 48-lead flatpacks.
Military grade product is manufactured in compliance with the latest
revision of MIL-PRF-38535 QML, making it ideally suited to military
temperature applications demanding the highest level of performance
and reliability.
Both devices provide two independent ports with separate control,
