Product Description
Product Overview
The CMT826X series are high-performance, six-channel digital isolators utilizing SiO2 isolation technology, supporting up to 5.7kVrms isolation voltage. These isolators facilitate communication between different power domains, preventing noise currents from affecting sensitive circuits. They offer enhanced electromagnetic compatibility (EMC) with system-level ESD, EFT, and surge immunity, along with low radiation. Available in SOIC-16 wide and narrow body packages, the CMT826X series provides robust and reliable isolation for demanding applications.
