Product Summary
The SN74LVC139APWR is a dual 2-line to 4-line decoder/demultiplexer. It 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 decoder/demultiplexer features fully buffered inputs, each of which represents only one normalized load to its driving circuit.
