The SN74F151AN is a logic implementation of a single-pole, 8-position switch with the switch position controlled by the state of three Select inputs. True and complementary outputs are both provided. The Enable input is active Low. When E is High, the Y\ output is High and the Y output is Low, regardless of all other inputs. In one package the SN74F151AN provides the ability to select from eight sources of data or control information. The device can provide any logic function of four variables and the negation with correct manipulation.
