3-to-8 line decoder, demultiplexer with address latches;

inverting

Rev. 03 — 11 November 2004

Product data sheet

1. General description

The 74HC137 is a high-speed Si-gate CMOS device and is pin compatible with low power

Schottky TTL (LSTTL). The 74HC137 is speciﬁed in compliance with JEDEC

standard no. 7A.

The 74HC137 is a 3-to-8 line decoder, demultiplexer with latches at the three address

inputs (An). The 74HC137 essentially combines the 3-to-8 decoder function with a 3-bit

storage latch. When the latch is enabled (LE = LOW), the 74HC137 acts as a 3-to-8 active

LOW decoder. When the latch enable (LE) goes from LOW-to-HIGH, the last data present

at the inputs before this transition, is stored in the latches. Further address changes are

ignored as long as LE remains HIGH.

The output enable input (E1 and E2) controls the state of the outputs independent of the

address inputs or latch operation. All outputs are HIGH unless E1 is LOW and E2 is HIGH.

The 74HC137 is ideally suited for implementing non-overlapping decoders in 3-state

systems and strobed (stored address) applications in bus oriented systems.

2. Features
