Overview
TECHNICAL DATA IN74HC373A Octal 3-State Noninverting Transparent Latch High-Performance Silicon-Gate CMOS The IN74HC373A is identical in pinout to the LS/ALS373.
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 Latch Enable is high.
When Latch Enable goes low, data meeting the setup and hold time becomes latched.
The Output Enable input does not affect the state of the latches, but when Output Enable is high, all device outputs are forced to the highimpedance state.
Thus, data may be latched even when the outputs are not enabled.
