SN74HCS151/SN74HCS151-Q1 8-to-1 Multiplexers Texas Instruments SN74HCS151/SN74HCS151-Q1 8-to-1 Multiplexers contains full binary decoding to select one of eight data sources and complementary outputs. 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 Texas Instruments SN74HCS151-Q1 devices are AEC-Q100 qualified for automotive applications.
