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
