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.
