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 forced to the high-impedance state; thus, data may be stored even when the outputs are not enabled.
