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,
