HD74AC139/HD74ACT139

Dual 1-of-4 Decoder/Demultiplexer

ADE-205-369 (Z)

1st. Edition

Sep. 2000

Description

The HD74AC139/HD74ACT139 is a high-speed, dual 1-of-4 decoder/demultiplexer. The device has two

independent decoders, each accepting two inputs and providing four mutually-exclusive active-Low

outputs. Each decoder has an active-Low Enable input which can be used as a data input for a 4-output

demultiplexer. Each half of the HD74AC139/HD74ACT139 can be used as a function generator providing

all four minterms of two variables.

Features

• Multifunction Capability

• Two Completely Independent 1-of-4 Decoders

• Active Low Mutually Exclusive Outputs

• Outputs Source/Sink 24 mA

• HD74ACT139 has TTL-Compatible Inputs

Functional Description

The HD74AC139/HD74ACT139 is a high-speed dual 1-of-4 decoder/demultiplexer. The device has two

independent decoders, each of which accepts two binary weighted inputs (A0 to A1) and provides four

mutually exclusive active-Low outputs (O0 to O3). Each decoder has an active-Low enable ( E). When E is

High all outputs are forced High. The enable can be used as the data input for a 4-output demultiplexer

application. Each half of the HD74AC139/HD74ACT139 generates all four minterms of two variables.

These four minterms are useful in some applications, replacing multiple gate functions as shown in Figure

a, and thereby reducing the number of packages required in a logic network.
