In a motor drive or industrial inverter where the switching edges on the high-voltage rail couple fast transients across the barrier, that figure tells you the isolator won't glitch or latch the I²C data. The 1ns typical rise and fall times keep the bus edges clean enough for the 100kHz clock rate. ## Supply range and 3.3V compatibility The supply range spans 3V to 5.5V, so it works on a 3.3V I²C bus as well as a 5V bus. The two channels are unidirectional — one from Side 1 to Side 2 (typically SDA), one the opposite direction (SCL) — matching the standard I²C topology where each line needs its own direction. ## Package and temperature grade Housed in a 10-MSOP (3mm × 3mm body), it's a surface-mount part that reflows without special handling — MSL 1 or 2 per the usual Analog Devices MSOP profile.","metaTitle":"LTC4310IMS-1#PBF I²C Digital Isolator, 20kV/µs CMTI, 10-MSOP","metaDescription":"LTC4310IMS-1#PBF I²C digital isolator from Analog Devices.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Digital Isolators"],"specifications":{"Type":"I²C","Package":"Tube","Data Rate":"100kHz","Technology":"Magnetic Coupling","Channel Type":"Unidirectional","Mounting Type":"Surface Mount","Isolated Power":"No","Package / Case":"10-TFSOP, 10-MSOP (0.118\\\", 3.00mm Width)","lifecycle_stage":"eol_hot","Voltage - Supply":"3V ~ 5.5V","Number of Channels":"2","Operating Temperature":"-40°C ~ 85°C","Inputs - Side 1/Side 2":"1/1","Rise / Fall Time (Typ)":"1ns, 1ns","Supplier Device Package":"10-MSOP","Common Mode Transient Immunity (Min)":"20kV/µs"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$5.78","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$5.78000","currency":"USD"},{"qty":10,"price":"$5.19200","currency":"USD"},{"qty":25,"price":"$4.90880","currency":"USD"},{"qty":100,"price":"$4.25410","currency":"USD"},{"qty":250,"price":"$4.03596","currency":"USD"},{"qty":500,"price":"$3.62146","currency":"USD"},{"qty":1000,"price":"$3.05424","currency":"USD"},{"qty":2500,"price":"$2.90153","currency":"USD"}]},"links":{"datasheetUrl":"https://www.analog.com/media/en/technical-documentation/data-sheets/431012fa.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Does LTC4310IMS-1#PBF require isolated power on both sides?","answer":"No, the LTC4310IMS-1#PBF does not require isolated power on the secondary side.
