Dual 2-to-4-line Decoders/Demultiplexers
REJ03D0571-0300
Rev.3.00
Mar 25, 2009
Description
The HD74HC139 contains two independent two-to-four-line decoders each with a single active low enable input (1G or
2G). Data on the select inputs (1A and 1B or 2A and 2B) cause one of the four normally high outputs to go low.
