74AC151 • 74ACT151
8-Input Multiplexer
General Description
The AC/ACT151 is a high -speed 8-input digital mu l tipl ex er.
It provides, in one package, the ability to select o ne line of
data from up to eight sources. The AC/ACT151 can be
used as a universal function generator to generate any
logic function of four variable s. Both true and comple mentary outputs are provided.
Features
■ ICC reduced by 50%
■ Outputs source/sink 24 mA
■ ACT151 has TTL-compatible inputs
Ordering Code:
Device also available in Tape and Reel. Specify by appending s uffix let te r “X” to the ordering code.

Functional Description
The AC/ACT151 is a logic imple mentat ion of a sing le pole,
8-position switch with the switch pos ition controlle d by the
state of three Select inputs, S
0
, S1, S2. Both true and com-
plementary outputs are provided. The En able input (E
) is
active LOW. When it is not activa ted, the complementary
output is HIGH and the true output is LOW regardless of all
other inputs. The logic function provided at the output is:
Z = E
• (I0 • S0 • S1 • S2 + I1 • S0 • S1 • S2 +

S

• S1 • S2 + I6 • S0 • S1 • S2 + I 7 • S0 • S1 • S2)
The AC/ACT151 provides the ability, in one package, to
select from eight sources of data or con trol info rmatio n. By
proper manipulation of the inputs, the AC/ACT151 can provide any logic function of four variables and its complement.

Absolute Maximum Ratings(Note 1) Recommended Operating
Conditions
Note 1: Absolute max imum ratings are those values beyond w hich damage
to the device may occu r. The databook spe cificatio ns shou ld be met, wit hout exception, to ensure that the system de sign is relia ble over its p ower
supply, temperature, and output/input loading variables. Fairchild does not
recommend operation of FACT circuits outside databook specif ic at ions.
