description
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.

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.
