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.
The SN54ALS151 is characterized for operation over the full military temperature range of -55°C to 125°C. The SN74ALS151 and SN74AS151 are characterized for operation from 0°C to 70°C.
