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 inputs. The logic function provided at the output is: Z e E # (I0 S2 S1 S0 a I1 S2 S1 S0 a I2 S2 S1 S0 a I3 S2 S1 S0 a I4 S2 S1 S0 a I5 S2 S1 S0 a I6 S2 S1 S0 a I7 S2 S1 S0) The ’F151A provides the ability, in one package, to select from eight sources of data or control information. By proper manipulation of the inputs, the ’F151A can provide any logic function of four variables and its negation.
