FEATURES

GENERAL DESCRIPTION

The 74HC/HCT374 are high-speed Si-gate CMOS devices

and are pin compatible with low power Schottky TTL

(LSTTL). They are specified in compliance with JEDEC

standard no. 7A.

The 74HC/HCT374 are octal D-type flip-flops featuring

separate D-type inputs for each flip-flop and 3-state

outputs for bus oriented applications. A clock (CP) and an

output enable (OE) input are common to all flip-flops.

The 8 flip-flops will store the state of their individual

D-inputs that meet the set-up and hold times requirements

on the LOW-to-HIGH CP transition.

When OE is LOW, the contents of the 8 flip-flops are

available at the outputs. When OE is HIGH, the outputs go

to the high impedance OFF-state. Operation of the

OE input does not affect the state of the flip-flops.

The “374” is functionally identical to the “534”, but has

non-inverting outputs.
