The data rate is 100kHz, matching standard-mode I²C, and the supply range of 3V to 5.5V lets it sit on either a 3.3V or 5V bus without a level shifter. ## Two unidirectional channels — one per direction The part has two unidirectional channels, with one input on side 1 and one input on side 2. That means one channel carries data from the primary side to the isolated side, and the other carries it back — exactly what a two-wire I²C interface needs for the SDA and SCL lines. No isolated power is provided on-chip, so each side needs its own supply rail within the 3V to 5.5V range. Not for automotive under-hood, outdoor telecom cabinets, or industrial floor applications where ambient temperature exceeds 70°C.","metaTitle":"LTC4310CMS-1#PBF I²C Digital Isolator, 100kHz, 10-MSOP","metaDescription":"LTC4310CMS-1#PBF is an Analog Devices I²C digital isolator with 20kV/µs CMTI, 2 unidirectional channels, 3V–5.5V supply, 0°C–70°C.
