74LCX157
Low Voltage Quad 2-Input Multiplexer
with 5V Tolerant Inputs
General Description
The LCX157 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 LCX157 can also be used as a function generator.
The 74LCX157 is fabricated with advanced CMOS technol-
ogy to achieve high speed operation while maintaining
CMOS low power dissipation.
