DUAL 1-OF-4
DECODER/DEMULTIPLEXER
The MC74AC139/74ACT139 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 MC74AC139/74ACT139 can be used as a function generator providing
four minterms of two variables.
• 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 MC74AC139/74ACT139 is a high-speed dual 1-of-4
decoder/demultiplexer. The device has two independent
decoders, each of which accepts two binary weighted inputs

(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 MC74AC139/74ACT139
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.
