Product Overview

The CMT812X is a high-performance, dual-channel digital isolator utilizing silicon dioxide (SiO2) insulation technology, capable of supporting isolation voltages up to 5 kVrms. Designed for communication between two different power domains, it prevents noise currents on data buses or other circuits from entering the local ground, thereby avoiding interference and damage to sensitive circuitry. The CMT812X series offers enhanced electromagnetic compatibility (EMC) with low emissions and high immunity to system-level ESD, EFT, and surges. Available in SOIC-16 wide body, SOW8L wide body, and SOIC-8 narrow body packages.
