MC74HC533A - Octal 3-State Inverting Transparent Latch
MOTOROLA SEMICONDUCTOR TECHNICAL DATA Octal 3-State Inverting Transparent Latch High Performance Silicon Gate CMOS The MC54/74HC533A is identical in pinout to the LS533.
The device inputs are compatible with standard CMOS outputs; with pullup resistors, they are compatible with LSTTL outputs.
These latches appear transparent to data (i.e., the outputs change asynchronously) when Latch Enable is high.
The Data appears at the outputs in inverted form.
When Latch Enable goes low,
