74151 Data Selectors/Mux

This data selector/multiplexer contains full on-chip decoding to select the desired data source. The ‘LS151 selects one of eight data sources. The ‘LS151 has a strobe input which must be at a low logic level to enable these devices. A high level at the strobe forces the W output high, and the Y output low. The ‘LS151 features complementary W and Y outputs.
