SN74LS151

8-Input Multiplexer

The TTL/MSI SN74LS151 is a high speed 8-input Digital
Multiplexer. It provides, in one package, the ability to select one bit of
data from up to eight sources. The LS151 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

The LS151 is a logical implementation of a single pole,
8-position 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:

Z = E ⋅ (I0 ⋅ S0 ⋅ S1 ⋅ S2 + ⋅ I1 ⋅ S0 ⋅ S1 ⋅ S2 + I2 ⋅ S0 ⋅ S1 ⋅ S

2

+ I3 ⋅ S0 ⋅ S1 ⋅ S2 + I4 ⋅ S0 ⋅ S1 ⋅ S2 + I5 ⋅ S0 ⋅ S1 ⋅ S2 + I

6

⋅

S

0

⋅ S1 ⋅ S2 + I7 ⋅ S0 ⋅ S1 ⋅ S2).

The LS151 provides the ability, in one package, to select
from eight sources of data or control information. By proper
manipulation of the inputs, the LS151 can provide any logic
function of four variables and its negation.
