IN74HC573A, Octal Transparent Latch

TECHNICAL DATA IN74HC573A Octal 3-State Noninverting Transparent Latch High-Performance Silicon-Gate CMOS N SUFFIX PLASTIC DIP 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.
