GENERAL DESCRIPTION
The 74HC/HCT534 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/HCT534 are octal D-type flip-flops featuring
separate D-type inputs for each flip-flop and inverting
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 “534” is functionally identical to the “374”, but has
inverted outputs.
