74LVQ157
Low Voltage Quad 2-Input Multiplexer
General Description
The LVQ157 is a high-speed quad 2-input multiplexer. Four
bits of data from two sources can be selected using the com-
mon Select and Enable inputs. The four outputs present the
selected data in the true (noninverted) form. The LVQ157
can also be used as a function generator.
Features
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.
