Functional Description
The F151A is a logic implementation of a single pole, 8-
position switch with the switch position controlled by the
state of three Select inputs, S

. Both assertion and
negation outputs are provided. The Enable input (E) is
active LOW. When it is not activated, the negation output is
HIGH and the assertion output is LOW regardless of all
other inputs. The logic function provided at the output is:

The F151A provides the ability, in one package, to select
from eight sources of data or control information. By proper
manipulation of the inputs, the F151A can provide any logic
function of four variables and its negation.
