Outputs

The LVQ151 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 com-
plementary 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
• S 0
• S 1
• S 2 + I1
• S0
• S 1
• S 2 +

I2
• S 0
• S1
• S 2 + I3
• S0
• S1
• S 2 +

I4
• S 0
• S 1
• S2 + I5
• S0
• S 1
• S 2 +

I6
• S 0
• S1
• S2 + I7
• S0
• S1
• S 2

The LVQ151 provides the ability, in one package to select
from eight sources of data or control information. By proper

H = HIGH Voltage Level L = LOW Voltage Level X = Immaterial
manipulation of the inputs, the LVQ151 can provide any logic function of four variables and its complement.
