74F151A 8-Input Multiplexer
General Description
The F151A 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 F151A can be used as a universal function generator to generate any logic function of four variables. Both assertion and negation outputs are provided.

74F151A
Functional Description
The F151A is a logic implementation of a single pole, 8position switch with the switch position controlled by the state of three Select inputs, S0, S1, 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 inputs. The logic function provided at the output is: Z = E · (I0 S2 S1 S0 + I1 S2 S1 S0 + I2 S2 S1 S0 + I3 S2 S1 S0 + I4 S2 S1 S0 + I5 S2 S1 S0 + I6 S2 S1 S0 + 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.
