Overview
The NLVASB3157DFT2G, produced by onsemi, is an advanced CMOS analog switch fabricated with silicon gate CMOS technology. This device is designed to achieve very low propagation delay and RDSON resistances while maintaining low power dissipation. It is a drop-in replacement for the NC7SB3157 and features overvoltage protection on the select pin, allowing voltages up to 7.0 V without damage. The NLVASB3157DFT2G is available in tiny SC88 and WDFN6 packages and is Pb-free, halogen-free, and RoHS compliant.
