TECHNICAL DATA
Octal 3-State Noninverting
Transparent Latch
High-Performance Silicon-Gate CMOS
IN74AC573
The IN74AC573 is identical in pinout to the LS/ALS573,
HC/HCT573. The device inputs are compatible with standard CMOS
outputs; with pullup resistors, they are compatible with LS/ALS 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; 0.1 µA @ 25°C
High Noise Immunity Characteristic of CMOS Devices
Outputs Source/Sink 24 mA
