The PI3CH401 is a low voltage, 4-channel switch
designed with fast individual enables. The switch
introduces no additional ground bounce noise or
additional propagation delay.
The PI3CH401 device has 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
