MC74HC563A - Octal 3-State Inverting Transparent Latch
MOTOROLA SEMICONDUCTOR TECHNICAL DATA Octal 3-State Inverting Transparent Latch High Performance Silicon Gate CMOS The MC54/74HC563A is identical in pinout to the LS563.
The device inputs are compatible with standard CMOS outputs; with pullup resistors, they are compatible with LSTTL outputs.
This device is identical in function to the HC533A but has the Data Inputs on the opposite side of the package from the outputs to facilitate PC board layout.
These latches appear transpar
