Logic device/transceiver/encoder

Octal, 150mA/Channel D-Type Latch 20-SOIC

The MC74AC139/74ACT139 is a high-speed dual 1/4 decoder/demultiplexer that features two independent decoders, each accepting two inputs and providing four mutually exclusive active-low outputs. Each decoder has an active low input that can be used as the data input for the 4 output demultiplexers. Each half of the MC74AC139/74ACT139 can be used as a function generator, providing four min-terms of two variables.
