TECHNICAL DATA IN74HC574A Octal 3-State Noninverting D Flip-Flop High-Performance Silicon-Gate CMOS N SUFFIX PLASTIC DIP The IN74HC574A is identical in pinout to the LS/ALS574.
The device inputs are compatible with standard CMOS outputs; with pullup resistors, they are compatible with LS/ALSTTL outputs.
Data meeting the setup time is clocked to the outputs with the rising edge of the Clock.
The OE input does not affect the states of the flip-flops, but when OE is high, all device outputs are
