SL74HC573
Octal 3-State Noninverting Transparent Latch
High-Performance Silicon-Gate CMOS
The SL74HC573 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 Latch Enable is high. When Latch Enable 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
