Description

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).
