54AC151/54ACT151 8-Input Multiplexer
General Description
The 'AC/'ACT151 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 'AC/'ACT151 can be used as a universal function generator to generate any logic function of four variables. Both true and complementary outputs are provided. n 'ACT151 has TTL-compatible inputs n Standard Microcircuit Drawing (SMD) -- 'AC151: 5962-87691 -- 'ACT151: 5962-88756 n 54AC151 now qualified to 300Krad RHA designation, refer to the SMD for more information

Functional Description
The 'AC/'ACT151 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 'AC/'ACT151 provides the ability, in one package to select from eight sources of data or control information. By proper manipulation of the inputs, the 'AC/'ACT151 can provide any logic function of four variables and its complement.

Note 1: Absolute maximum ratings are those values beyond which damage to the device may occur. The databook specifications should be met, without exception, to ensure that the system design is reliable over its power supply, temperature, and output/input loading variables. National does not recommend operation of FACT ® circuits outside databook specifications.
