Description of 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. Features Select one-of-eight data lines Performs parallel-to-serial conversion Permits multiplexing from N lines to one line Also for use as Boolean function generator Typical average propagation delay time data input to W output 12.5 ns Typical power dissipation 30 mW Alternate Military/Aerospace device (54LS151) is available.Contact a National Semiconductor Sales Office/Distributor for specifications.
