description
This dual 2-line to 4-line decoder/demultiplexer 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. 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 3.3-V or 5-V devices. This feature allows the use of these devices as translators
in a mixed 3.3-V/5-V system environment.
The SN74LVC139A is characterized for operation from –40
°C to 85°C.
