74ACT139 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 of which accepts two binary weighted inputs (A0 *A1) and provides four mutually exclusive active-LOW outputs (O 0 *O3). Each decoder has an active-LOW enable (E). Whe.

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.
