Pin Names E Z Description Data Inputs Select Inputs Enable Input Data Output Inverted Data Output
The is a logic implementation of a single pole, 8-position switch with the switch position controlled by the state of three Select inputs, 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: 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. Fairchild does not recommend operation of FACT circuits outside databook specifications.
