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.

Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and
functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
NOTES: 1. The input negative-voltage and output voltage ratings may be exceeded if the input and output current ratings are observed.
2. The value of VCC is provided in the recommended operating conditions table.
3. The package thermal impedance is calculated in accordance with JESD 51-7.
