MC74AC139, MC74ACT139

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.
