Texas Instruments CD74AC151 8-Input Data Selector/Multiplexer
Texas Instruments CD74AC151 8-Input Data Selector/Multiplexer provides full binary decoding to select one of eight data sources. To enable the inputs, the strobe (G) input must be at a low logic level. A high level at the strobe terminal forces the W output to be high and the Y output to be low. The Texas Instruments CD74AC151 has a balanced noise immunity at 30% of the supply voltage and a 1.5V to 5.5V operating range.
