74AC139 • 74ACT139 Dual 1-of-4 Decoder/Demultiplexer November 1988 Revised November 1999 74AC139 • 74ACT139 Dual 1-of-4 Decoder/Demultiplexer General Description The AC/ACT139 is a high-speed, dual 1-of-4 decoder/ demultiplexer. The device has two independent decoders, each accepting two inputs and providing four mutuallyexclusive 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 AC/ ACT139 can be used as a function generator providing all four minterms of two variables. Features s ICC reduced by 50% s Multifunction capability s Two completely independent 1-of-4 decoders s Active LOW mutually exclusive outputs s Outputs source/sink 24 mA s ACT139 has TTL-compatible inputs Ordering Code: O [ ... ]
