MC74F151

    The MC54/74F151 is a high-speed 8-input digital multiplexer. It provides in one package, the ability to select one line of data from up to eight sources. The F151 MC74F151 can be used as a universal function generator to generate any logic function of four variables. Both asserted and negated outputs are provided. The F151 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.The Enable input (E) is active LOW. 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)
