74F151A8-input multiplexer

FEA TURES

•High speed 8-to-1 multiplexing

•On chip decoding

•Multifunction capability

•Complementary outputs

DESCRIPTION

The 74F151A is a logic implementation of a single-pole, 8-position
switch with the switch position controlled by the state of three Select
(S0, S1, S2) inputs. True (Y) and complementary (Y
both provided. The Enable input (E

output is High and the Y output is Low, regardless of all other

the Y

) is active Low. When E is High,

inputs. In one package the 74F151A provides the ability to select
from eight sources of data or control information. The device can
provide any logic function of four variables and the negation with
correct manipulation.
