Pin Configuration
The PI3CH3305 is a Low-voltage, 2-channel switch
designed with fast individual enable. The switch creates
no additional ground bounce noise or propagation delay.
The PI3CH3305 device has an active High enable.
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
