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.
