That isolation rating meets reinforced-grade requirements per IEC 60747-17, so it handles the safety barrier between a low-voltage controller and a high-side I²C sensor or actuator without needing a separate isolated DC-DC converter. Three of the four channels are bidirectional (the I²C data and clock lines), and one is unidirectional — a common topology for isolating an I²C bus where the master and slave sit on different ground references. The 3/3 input-to-output count means three inputs on side 1 map to three outputs on side 2, with the remaining channel reversed. ## Common-mode transient immunity and temperature range A minimum common-mode transient immunity of 35 kV/µs means the isolator maintains data integrity when a fast voltage transient (like a motor-drive PWM edge or a lightning surge) slams the ground planes apart. Below that slew rate, the capacitive coupling still tracks the input; above it, the output may glitch. For a motor-drive or industrial inverter environment where 10–20 kV/µs transients are routine, this part has margin.","metaTitle":"Skyworks SI8605AD-B-IS I²C Digital Isolator, 5000Vrms, 4-Ch","metaDescription":"SI8605AD-B-IS I²C digital isolator, 5000Vrms isolation, 4 channels, 35kV/µs CMTI, -40°C to 125°C, 16-SOIC.
