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

common Select and Enable inputs. The four outputs

present the selected data in the true (non inverted) form.

The LVQ157 can also be used as a function generator.

Features

s Ideal for low power/low noise 3.3V applications

s Guaranteed simultaneous switching noise level and

dynamic threshold performance

s Guaranteed pin-to-pin skew AC performance

s Guaranteed incident wave switching into 75Ω.
