TECHNICAL DATA
KK74HC574A
Octal 3-State Noninverting D Flip-Flop
High-Performance Silicon-Gate CMOS
N SUFFIX PLASTIC DIP
The KK74HC574A 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. • • • • Outputs Directly Interface to CMOS, NMOS, and TTL Operating Voltage Range: 2.0 to 6.0 V Low Input Current: 1.
