description/ordering information
These data selectors/multiplexers provide full binary decoding to select one of eight data sources. The strobe
(G) input must be at a low logic level to enable the inputs. A high level at the strobe terminal forces the W output
high and the Y output low.

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 and output voltage ratings may be exceeded if the input and output current ratings are observed.
2. The package thermal impedance is calculated in accordance with JESD 51-7.
