FUNCTIONAL DESCRIPTION
The MC74AC151/74ACT151 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
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(I0S0S1S2+I1S0S1S2+
I2S0S1S2+I3S0S1S2+
I4S0S1S2+I5S0S1S2+
I6S0S1S2+I7S0S1S2)
The MC74AC151/74ACT151 provides the ability, in one
package, to select from eight sources of data or control
information. By proper manipulation of the inputs, the
MC74AC151/74ACT151 can provide any logic function of
four variables and its complement.
