Description

The PI3CH800 is a low voltage, 8-channel switch

designed with fast individual enables. The switch

introduces no additional ground bounce noise or

additional propagation delay.

The PI3CH800 device has active low enables. It is

very useful in switching signals that have high

bandwidth (500 MHz).
