Octal 3-State Noninverting Transparent Latch High-Performance Silicon-Gate CMOS

The IN74HC573A is identical in pinout to the LS/ALS573. The device inputs are compatible with standard CMOS outputs; with pullup resistors, they are compatible with LS/ALSTTL outputs.

These latches appear transparent to data (i.e., the outputs change asynchronously) when LE is high. When LE goes low, data meeting the setup and hold time becomes latched.

• Outputs Directly Interface to CMOS, NMOS, and TTL

• Operating Voltage Range: 2.0 to 6.0 V

• Low Input Current: 1.0 µA

• High Noise Immunity Characteristic of CMOS Devices
