FEATURES

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) outputs are

both provided. The Enable input (E) is active Low. When E is High,

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

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.
