TECHNICAL DATA
IN74HC374A
Octal 3-State
Noninverting D Flip-Flop
High-Performance Silicon-Gate CMOS
The IN74HC374A 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
