1. General description

2. Features

The 74HC138; 74HCT138 is a high-speed Si-gate CMOS device and is pin compatible

with Low-power Schottky TTL (LSTTL).

The 74HC138; 74HCT138 decoder accepts three binary weighted address inputs (A0, A1

and A3) and when enabled, provides 8 mutually exclusive active LOW outputs (Y0 to Y7).

The 74HC138; 74HCT138 features three enable inputs: two active LOW (E1 and E2) and

one active HIGH (E3). Every output will be HIGH unless E1 and E2 are LOW and E3 is

HIGH.

This multiple enable function allows easy parallel expansion of the 74HC138; 74HCT138

to a 1-of-32 (5 lines to 32 lines) decoder with just four 74HC138; 74HCT138 ICs and one

inverter.

The 74HC138; 74HCT138 can be used as an eight output demultiplexer by using one of

the active LOW enable inputs as the data input and the remaining enable inputs as

strobes. Not used enable inputs must be permanently tied to their appropriate active

HIGH- or LOW-state.

The 74HC138; 74HCT138 is identical to the 74HC238; 74HCT238 but has inverting

outputs.

74HC138; 74HCT138

3-to-8 line decoder/demultiplexer; inverting

Rev. 03 — 23 December 2005

Demultiplexing capability

Multiple input enable for easy expansion

Complies with JEDEC standard no. 7A

Ideal for memory chip select decoding

Active LOW mutually exclusive outputs

ESD protection:

Speciﬁed from 40 C to +85 C and from 40 C to +125 C

HBM EIA/JESD22-A114-C exceeds 2000 V

MM EIA/JESD22-A115-A exceeds 200 V
