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.
