DESCRIPTION

The M74HC77 is an high speed CMOS 4 BIT D

TYPE LATCH fabricated with silicon gate C2MOS

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. The data

applied to the data inputs (1D, 2D, or 3D, 4D) are

transferred to the Q outputs (1Q, 2Q, or 3Q, 4Q)

respectively when the enable input (G1

•2 or G3•4)

is taken high. The Q outputs will follow the data

inputs 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 Q outputs.

All inputs are equipped with protection circuits

against static discharge and transient excess

voltage.
