74ACT139 Datasheet | Fairchild Semiconductor

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. - - - - - Multifunction Capability Two pletely Independent 1-of-4 Decoders Active LOW Mutually Exclusive Outputs Outputs Source/Sink 24 mA ′ACT139 Has TTL patible Inputs VCC 16 Eb 15 A0b 14 A1b 13 O0b 12 O1b 11 O2b...
