TECHNICAL DATA
Octal 3-State
Noninverting D Flip-Flop
High-Performance Silicon-Gate CMOS
KK74HC374A
The KK74HC374A is identical in pinout to the LS/ALS374. The
device inputs are compatible with standard CMOS outputs; with pullup
resistors, they are compatible with LS/ALSTTL outputs.
Data meeting the setup and hold time is clocked to the outputs with
the rising edge of the Clock. The Output Enable input does not affect the
states of the flip-flops, but when Output Enable is high, the 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: 1.0 µA
• High Noise Immunity Characteristic of CMOS Devices
