74LVX157

Low Voltage Quad 2-Input Multiplexer

General Description

The LVX157 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 (noninverted) form.

The LVX157 can also be used as a function generator.

Features

s Input voltage level translation from 5V to 3V

s Ideal for low power/low noise 3.3V applications

s Guaranteed simultaneous switching noise level and

dynamic threshold performance

Ordering Code:

Devices are also available in Tape and Reel. Specify by appending letter suffix “X” to the ordering code.
