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 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 Completely Independent 1-of-4 Decoders Active LOW Mutually Exclusive Outputs Outputs Source/Sink 24 mA ′ACT139 Has TTL Compatible Inputs
