These monolithic 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 data selection/multiplexing function. A high level at the strobe terminal forces the W output high and the Y output low.
The SN54F151B is characterized for operation over the full military temperature range of -55°C to 125°C. The SN74F151B is characterized for operation from 0°C to 70°C.
D0, D1,...D7 = the level of the respective D input.
