The PI74LVC139A comprises 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. Inputs can be driven from either 3.3V or 5.0V devices allowing the PI74LVC139A to be used as a translator in a mixed 3.3V/5.0V system.
