description/ordering information (continued)
The ’HC139 devices comprise two individual 2-line to 4-line decoders in a single package. The active-low enable
(G) input can be used as a data line in demultiplexing applications. These decoders/demultiplexers feature fully
buffered inputs, each of which represents only one normalized load to its driving circuit.
