Product Overview

The CMT812X series are high-performance, dual-channel digital isolators utilizing silicon dioxide (SiO2) isolation barriers, supporting up to 5 kVrms isolation voltage. These isolators facilitate communication between two different power domains, preventing noise currents from entering local grounds or interfering with sensitive circuits. The CMT812X offers two channels, with CMT812X1 featuring a default high output and CMT812X0 a default low output. They provide excellent electromagnetic compatibility (EMC) with low power consumption and low radiation, meeting system-level ESD, EFT, surge, and radiation compliance requirements through innovative chip design and layout. Available in SOIC-16 wide body, SOW8L wide body, and SOIC-8 narrow body packages.
