DESCRIPTION

The M74HCT75 is an high spe ed CMOS 4 BIT D
TYPE LATCH fabricated with silicon gate C

2

MOS
technology.
It contains two groups of 2 bit latches controlled by
an enable input (G1

•2 or G3•4). These two latch

groups can be used in different circuits. Each latch
has Q and Q

outputs (1Q - 4Q and 1Q - 4Q). The
data applied to the data input is transferred to the
Q and Q

outputs when the enable input is taken
high and the outputs will follow the data input as
long as the enable input is kept high. When the

enable input is taken low, the information data
applied to the data input is retained at the outputs.
The M74HCT75 is designed to directly interface

components.
All inputs are equipped with protection circuits
against static discharge and transient excess
voltage.
