Overview
The NLASB3157DFT2 is an advanced CMOS analog switch produced by onsemi, fabricated with silicon gate CMOS technology. It is designed to achieve very low propagation delay and RDS(ON) resistances while maintaining low power dissipation typical of CMOS devices. This switch can handle analog and digital voltages across the full power supply range (from VCC to GND) and is a drop-in replacement for the NC7SB3157. The control pins feature overvoltage protection, allowing voltages above VCC up to 7.0 V without disrupting the operation of the part.
