DM74150,DM74151AData Selectors/MultiplexersGeneral DescriptionThese data selectors/multiplexers contain full on-chip decod-ing to select the desired data source.The150selects one-of-sixteen data sources;the151A selects one-of-eight data sources.The150and151A have 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 (as applicable)low.The151A features complementary W and Y outputs, whereas the150has an inverted(W)output only.The151A incorporates address buffers which have sym-metrical propagation delay times through the complementary paths.This reduces the possibility of transients occurring at the output(s)due to changes made at the select inputs,even when the151A outputs are enabled(i.e.,strobe low).Featuresn150selects one-of-sixteen data linesn151A selects one-of-eight data linesn Performs parallel-to-serial conversionn Permits multiplexing from N lines to one linen Also
