The NSi810x devices are high reliability bidirectional isolators compatible with the I2C interface. They are AEC-Q100 qualified and safety certified by UL1577, supporting insulation withstand voltages of up to 5kVrms. These isolators offer high electromagnetic immunity, low emissions, and low power consumption. The I2C clock speed is up to 2MHz, with a common-mode transient immunity (CMTI) of up to 150kV/s. The wide supply voltage range allows direct connection to most digital interfaces for easy level shifting, enhancing system reliability and stability through high system-level EMC performance.
