Dual 2-Line To 4-Line Decoder/Demultiplexer

This dual 2-line to 4-line Decoder/Demultiplexer SN74LVC139A is designed for 1.65-V to 3.6-V VCC operation.
The device 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. This decoders/demultiplexers feature fully buffered inputs, each of which represents only one normalized load to its driving circuit.
Inputs CAN be driven from either 3.3-V or 5-V devices. This feature allows the use of this device as a translator in a mixed 3.3-V/5-V system environment.
