IN74AC573 Datasheet (IK Semiconductor) - Octal Transparent Latch

IN74AC573, Octal Transparent Latch

TECHNICAL DATA Octal 3-State Noninverting Transparent Latch High-Performance Silicon-Gate CMOS 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.
