Product Description
Product Overview
The CMT812X is a high-performance, dual-channel digital isolator utilizing silicon dioxide (SiO2) insulation for up to 5 kVrms isolation voltage. It facilitates communication between two different power domains, preventing noise currents from entering local grounds or interfering with sensitive circuits. The CMT812X series offers enhanced electromagnetic compatibility (EMC) with low radiation and high immunity to ESD, EFT, and surges. Available in SOIC-16 wide body, SOW8L wide body, and SOIC-8 narrow body packages.
