Product Description
CMT812X Series High-Speed Dual-Channel Digital Isolator
The CMT812X is a high-performance, dual-channel digital isolator designed for robust communication between different power domains. Utilizing silicon dioxide (SiO2) insulation, it provides up to 5 kVrms isolation voltage, effectively preventing noise currents and protecting sensitive circuits. The series offers enhanced electromagnetic compatibility (EMC) with system-level ESD, EFT, and surge immunity, along with low emissions. Available in multiple package options, it is suitable for demanding industrial and automotive applications.
