dual channel digital isolators HopeRF Micro electronics CMT8021N0L with silicon dioxide isolation barrier
Product Overview
The CMT802XNXL series are high-performance, dual-channel digital isolators utilizing silicon dioxide (SiO2) isolation barriers. They provide up to 3.75 kVRMS isolation voltage, enabling communication between two different power domains. These isolators prevent noise currents on data buses or other circuits from entering local grounds, thereby protecting sensitive circuitry from interference and damage. The CMT802XNXL series offers enhanced electromagnetic compatibility (EMC) with low power consumption and low emissions, meeting system-level ESD, EFT, surge, and radiation compliance requirements. Available in a narrow SOIC-8 package.
