By proper manipulation of the inputs, the 'AC/'ACT151 can provide any logic function of four variables and its complement. 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 E # (I0 # S0 # S1 # S2 a I1 # S0 # S1 # S2 a I2 # S0 # S1 # S2 a I3 # S0 # S1 # S2 a I4 # S0 # S1 # S2 a I5 # S0 # S1 # S2 a I6 # S0 # S1 # S2 a I7 # S0 # S1 # S2) Logic Diagram TL/F/9927 - 4 Please note that this diagram is provided only for the understanding of logic operations and should not be used to estimate propagation delays. 2 Absolute Maximum Ratings (Note 1) Recommended Operating Conditions If Military/Aerospace specified devices are required, please contact the National Semiconductor Sales Office/Distributors for availability and specifications.
