MC74AC139, MC74ACT139
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.
