74HC573的详细信息

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 mA
