Please note: As part of the Fairchild Semiconductor integration, some of the Fairchild orderable part numbers

will need to change in order to meet ON Semiconductor’s system requirements. Since the ON Semiconductor

product management systems do not have the ability to manage part nomenclature that utilizes an underscore

(_), the underscore (_) in the Fairchild part numbers will be changed to a dash (-). This document may contain

device numbers with an underscore (_). Please check the ON Semiconductor website to verify the updated

device numbers. The most current and up-to-date ordering information can be found at www.onsemi.com. Please

email any questions regarding the system integration to Fairchild_questions@onsemi.com.

Dual 1-of-4 Decoder /

Demultiplexer

General Description

The AC/ACT139 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 AC/ACT139 can

be used as a function generator providing all four minterms of two

variables.

Features

•ICC Reduced by 50%

•Multifunction Capability

•Two Completely Independent 1−of−4 Decoders

•Active LOW Mutually Exclusive Outputs

•Outputs Source/Sink 24 mA

•ACT139 has TTL−compatible Inputs

Functional Description

The AC/ACT139 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–A1)

and provides four mutually exclusive active−LOW outputs

(O0–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 AC/ACT139 generates all four

minterms of two variables. These four minterms are useful

in some applications, replacing multiple gate functions as

shown in Figure 1, and thereby reducing the number of

packages required in a logic network.
