Overview
MC74AC139 MC74ACT139
Dual 1ĆofĆ4 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.
