Fairchild F151A 8-input multiplexer Datasheet

Revised September 2000
74F151A
8-Input Multiplexer
General Description
The F151A is a high-speed 8-input digital multiplexer. It
provides 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, 8position switch with the switch position controlled by the
state of three Select inputs, S0, S1, S2. 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.
