INTEGRATED CIRCUITS 74ALS151 8-input multiplexer Product specification IC05 Data Handbook 1991 Feb 08 Philips Semiconductors Philips Semiconductors Product specification 8-input multiplexer 74ALS151 FEATURES 8-to-1 multiplexing On chip decoding Multi-function capability Complementary outputs See 74ALS251 for 3-State version DESCRIPTION The 74ALS151 is a logic implementation of a single 8-position switch with the switch position controlled by the state of three select (S0, S1, S2) inputs. True (Y) and complementary (Y) outputs are both provided. The enable (E) is active-Low. When E is High, Y output is Low and the Y output is High regardless of all other inputs.
