MC74AC139, MC74ACT139  
Dual 1−of−4  
Decoder/Demultiplexer  
The MC74AC139/74ACT139 is a highspeed, dual 1of4  
decoder/demultiplexer. The device has two independent decoders,  
each accepting two inputs and providing four mutuallyexclusive  
activeLOW outputs. Each decoder has an activeLOW Enable input  
which can be used as a data input for a 4output demultiplexer. Each  
half of the MC74AC139/74ACT139 can be used as a function  
generator providing four minterms of two variables.
