description/ordering information
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.
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-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.
