The NLAS3158 is an advanced CMOS analog switch fabricated with silicon gate CMOS technology. It achieves very low propagation delay and RDSON resistances while maintaining CMOS low power dissipation. Analog and digital voltages that may vary across the full power−supply range (from VCC to GND). This device is a drop in replacement for the PI5A3158.
The select pin has overvoltage protection that allows voltages above VCC, up to 7.0 V to be present on the pin without damage or disruption of operat ion of the part , regardless of the operating voltage.

Maximum ratings are those values beyond which device damage can occur. Maximum ratings applied to the device are individual stress limit values (not normal operating conditions) and are not valid simultaneously. If these limits are exceeded, device functional operation is not implied, damage may occur and reliability may be affected. 1. The input and output negative voltage ratings may be exceeded if the input and output diode current ratings are observed.
