Dual 1-of-4 DecoderDemultiplexer
General Description
The ’F139 is a high-speed dual 1-of-4 decoderdemultiplex-
er The device has two independent decoders each accept-
ing two inputs and providing four mutually exclusive active
LOW outputs Each decoder has an active LOW Enable in-
put which can be used as a data input for a 4-output demul-
tiplexer Each half of the ’F139 can be used as a function
generator providing all four minterms of two variables
