The SN74LVC139APW is a dual 2-to-4 Decoder/Demultiplexer designed for 1.65 to 3.6V VCC operation. The active-low enable (G\\) input can be used as a data line in demultiplexing applications. This decoder/demultiplexer features fully buffered inputs, each of which represents only one normalized load to its driving circuit. Inputs can be driven from either 3.3 or 5V devices. This feature allows the use of this device as a translator in a mixed 3.3/5V system environment.
