描述

The LTC3157 is an advanced CMOS analog switch fabricated with silicon gate CMOS technology. It achieves very low propagation delay while maintaining CMOS low power dissipation. Analog and
digital voltages that may vary across the full power-supply range (from VCC to GND). 

The Select pin has over voltage protection that allows voltages above VCC, up to 7.0 V to be present on the pin without damage or disruption of operation of the part, regardless of the operating voltage.
