MM54HC137/MM74HC137 3-to-8 Line

Decoder With Address Latches

(Inverted Output)

General Description

This device utilizes advanced silicon-gate CMOS technolo-

gy, to implement a three-to-eight line decoder with latches

on the three address inputs. When GL goes from low to

high, the address present at the select inputs (A, B and C) is

stored in the latches. As long as GL remains high no ad-

dress changes will be recognized. Output enable controls,

G1 and G2, control the state of the outputs independently of

the select or latch-enable inputs. All of the outputs are high

unless G1 is high and G2 is low. The HC137 is ideally suited

for the implementation of glitch-free decoders in stored-ad-

dress applications in bus oriented systems.

The 54HC/74HC logic family is speed, function and pin-out

compatible with the standard 54LS/74LS logic family. All

inputs are protected from damage due to static discharge by

diodes to V

and ground.

Features

Typical propagation delay: 20 ns

Wide supply range: 2–6V

Latched inputs for easy interfacing.

Fanout of 10 LS-TTL loads.
