multiplexer. 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 DUAL 1-OF-4 DECODER /
for a 4-output demultiplexer. Each half of the LS139 can be used as a function DEMULTIPLEXER
