TECHNICAL DATA
KK74HC573A
Octal 3-State Noninverting Transparent Latch
High-Performance Silicon-Gate
CMOS
N SUFFIX PLASTIC DIP
The KK74HC573A 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.
