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.
