74LVQ151
Low Voltage 8-Input Multiplexer
General Description
Features
The LVQ151 is a high-speed 8-input digital multiplexer. It
provides, in one package, the ability to select one line of data
from up to eight sources. The LVQ151 can be used as a universal function generator to generate any logic function of
four variables. Both true and complementary outputs are
provided.
n Ideal for low power/low noise 3.3V applications
n Guaranteed simultaneous switching noise level and
dynamic threshold performance
n Guaranteed pin-to-pin skew AC performance
n Guaranteed incident wave switching into 75Ω

Truth Table
Functional Description
Inputs
The LVQ151 is a logic implementation of a single pole,
8-position switch with the switch position controlled by the
state of three Select inputs, S0, S1, S2. Both true and
complementary outputs are provided. The Enable input (E) is
active LOW. When it is not activated, 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 • S 0 • S 1 • S 2 + I1 • S0 • S 1 • S 2 +
I2 • S 0 • S1 • S 2 + I3 • S0 • S1 • S 2 +
I4 • S 0 • S 1 • S2 + I5 • S0 • S 1 • S 2 +
I6 • S 0 • S1 • S2 + I7 • S0 • S1 • S 2)
The LVQ151 provides the ability, in one package to select
from eight sources of data or control information. By proper
manipulation of the inputs, the LVQ151 can provide any logic
function of four variables and its complement.
