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

. Both assertion and nega-
tion 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 in-
puts. 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.
