description
These monolithic 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 data
selection/multiplexing function. A high level at the
strobe terminal forces the W output high and the
Y output low.

implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
NOTE 1: The input voltage rating may be exceeded provided that the input current rating is observed.
