74AHC138; 74AHCT138

3-to-8 line decoder/demultiplexer; inverting

Rev. 4 — 2 April 2014

Product data sheet

1. General description

The 74AHC138; 74AHCT138 are high-speed Si-gate CMOS devices and are pin

compatible with Low power Schottky TTL (LSTTL). They are specified in compliance with

JEDEC standard No. 7A.

The 74AHC138; 74AHCT138 is a 3-to-8 line decoder/demultiplexer. It accepts three

binary weighted address inputs (A0, A1 and A2) and, when enabled, provides eight

mutually exclusive outputs (Y0 to Y7) that are LOW when selected.

There are 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 device to a 1-of-32

(5 lines to 32 lines) decoder with just four 74AHC138; 74AHCT138 devices and one

inverter. The 74AHC138; 74AHCT138 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. Unused enable inputs must be permanently tied to their appropriate

active HIGH or LOW state.

2. Features and benefits



Balanced propagation delays

All inputs have Schmitt-trigger action

Demultiplexing capability

Multiple input enable for easy expansion

Ideal for memory chip select decoding

Inputs accepts voltages higher than V

For 74AHC138 only: operates with CMOS input levels
