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. Features • Multifunctional Capability • Two Completely Independent 1−of−4 Decoders • Active LOW Mutually Exclusive Outputs • Outputs Source/Sink 24 mA • ′ACT139 Has TTL Compatible Inputs • These are Pb−Free Devices VCC Eb A0b A1b O0b O1b O2b O3b 16 15
