TECHNICAL DATA
IN74HC573A
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
