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.
www.onsemi.com
Features
• I Reduced by 50%
CC
• 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 (A –A )
0
1
and provides four mutually exclusive active−LOW outputs
(O –O ). Each decoder has an active−LOW enable (E).
0
3
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.
