•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.

Definitions
Short-form specification — The data in a short-form specification is extracted from a full data sheet with the same type number and title. For
detailed information see the relevant data sheet or data handbook.
Limiting values definition — Limiting values given are in accordance with the Absolute Maximum Rating System (IEC 134). Stress above one
or more of the limiting values may cause permanent damage to the device. These are stress ratings only and operation of the device at these or
at any other conditions above those given in the Characteristics sections of the specification is not implied. Exposure to limiting values for extended
periods may affect device reliability.
