MC74AC139: 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.
