The LS151 is a logical implementation of a single pole, 8-position switch with the switch position controlled by the state of three Select inputs, S0, S 1, S2. Both assertion and negation outputs are provided. The Enable input (E) is active LOW. When it is not activated, the negation output is HIGH and the assertion output is LOW regardless of all other inpu.
