54150 DM54150 DM74150 54151A DM54151A DM74151A Data Selectors Multiplexers
General Description
These data selectors multiplexers contain full on-chip decoding to select the desired data source The 150 selects one-of-sixteen data sources the 151A selects one-of-eight data sources The 150 and 151A 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 The 151A features complementary W and Y outputs whereas the 150 has an inverted (W) output only The 151A incorporates address buffers which have symmetrical 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 the 151A outputs are enabled (i e strobe low)
