It provides, in one package, the ability to select one bit of data from up to eight sources. The LS151 can be used as a universal function generator to generate any logic function of four variables. Both assertion and negation outputs are provided.

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 ⋅(I0 ⋅ S0 ⋅ S1 ⋅ S2 + ⋅ I1 ⋅ S0 ⋅ S1 ⋅ S2 + I2 ⋅ S0 ⋅ S1 ⋅S2 + I3 ⋅ S0 ⋅ S1 ⋅ S2 + I4 ⋅ S0 ⋅ S1 ⋅S2 + I5 ⋅ S0 ⋅ S1 ⋅ S2 + I6 ⋅ S0 ⋅ S1 ⋅ S2 + I7 ⋅S0 ⋅ S1 ⋅ S2). The LS151 provides the ability, in one package, to select from eight sources of data or control information. By proper manipulation of the inputs, the LS151 can provide any logic function of four variables and its negation.
