Product Description
Product Overview
The CMT812X is a high-performance, dual-channel digital isolator utilizing silicon dioxide (SiO2) insulation. It supports isolation voltages up to 5 kVrms and is designed for communication between two different power domains, preventing noise currents from affecting sensitive local ground or circuits. The CMT812X series offers enhanced electromagnetic compatibility (EMC) with system-level ESD, EFT, and surge immunity, as well as low radiation. It is available in SOIC-16 wide body, SOW8L wide body, and SOIC-8 narrow body packages.
