Pin Configuration
The PI3CH3345 is a Low-voltage, 8-channel switch
designed with fast enables. The switch creates no
additional ground bounce noise or propagation delay.
The PI3CH3345 device has two active LOW
enables. It is very useful in switching signals that have
high bandwidth (500 MHz).
Applications
 High Bandwidth Data Switching
 Hot-Docking
 Analog Signal Switching
 Differential Signal Switching
