High-reliability two-channel bi-directional I2C digital isolator

The NSi8100x series is a high-reliability bi-directional l2C digital isolator. It provides a variety of UL1577-qualified electrical isolated withstand voltages (3.75kVRms, 5kVrms), with high electromagnetic immunity and low radiation. It supports I2C clock at a frequency up to 2MHZ, with the common mode transient immunity (CMTI) of up to 150kV/μs. The wide power supply range allows them to  be directly connected to digital interfaces such as most of the MCUs, and can easily provide bidirectional level conversion. Its excellent system-level electromagnetic compatibility (EMC) performance enhances its reliability and stability.
