description
This monolithic data selector/multiplexer provides full binary decoding to select one-of-eight data sources. The
strobe output-enable (OE) 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.
The 74AC11151 is characterized for operation from − 40°C to 85°C.

† 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.
NOTE 1: The input and output voltage ratings may be exceeded if the input and output clamp-current ratings are observed.
