DECODER/DEMULTIPLEXER, DUAL, 1: 4, SOIC16; Logic Family / Base Number: 74AC139; Logic Type: Decoder / Demultiplexer; No. of Channels: 2Channels; Line Configuration: 1: 4; Supply Voltage Min: 2V; Supply Voltage Max: 6V; Logic Cas
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.
