DM74ALS151 1 of 8 Line Data Selector/Multiplexer DM74ALS151 1 of 8 Line Data Selector/Multiplexer This Data Selector/Multiplexer contains full on-chip decoding to select one-of-eight data sources as a result of a unique three-bit binary code at the Select inputs. Two complementary outputs provide both inverting and non-inverting buffer operation.
