FUNCTIONAL DESCRIPTION The MC74AC151/74ACT151 is a logic implementation of a single pole, 8-position switch with the switch position controlled by the state of three Select inputs, S0, S1, S2. Both true and complementary outputs are provided. The Enable input (E) is active LOW. When it is not activated, the complementary output is HIGH and the true 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 MC74AC151/74ACT151 provides the ability, in one package, to select from eight sources of data or control information. By proper manipulation of the inputs, the MC74AC151/74ACT151 can provide any logic function of four variables and its complement.
