8-Input Multiplexer
General Description
The ’F151A is a high-speed 8-input digital multiplexer It pro-
vides in one package the ability to select one line of data
from up to eight sources The ’F151A can be used as a
universal function generator to generate any logic function
of four variables Both assertion and negation outputs are
provided

Functional Description
Truth Table
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 S0 S1 S2 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
Z e E  (I0 S2 S1 S0 a I1 S2 S1 S0 a I2 S2 S1 S0 a
I3 S2 S1 S0 a I4 S2 S1 S0 a I5 S2 S1 S0 a
I6 S2 S1 S0 a I7 S2 S1 S0)
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
