Functional Description
The LVQ151 is a logic implementation of a single pole,
8-position switch with the switch position controlled by the
state of three Select inputs, S
, S
, S
. 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:

The LVQ151 provides the ability, in one package to select
from eight sources of data or control information. By proper
manipulation of the inputs, the LVQ151 can provide any logic
function of four variables and its complement.
