It integrates isolated power and magnetic coupling technology to provide galvanic isolation up to 2500Vrms between the I²C bus and the host controller. With a data rate of 400kHz, it supports standard and fast-mode I²C communication. The supply range of 3V to 3.6V makes it a direct fit for 3.3V I²C buses commonly found in industrial sensors, PLCs, motor drives, and isolated data-acquisition systems. The 400kHz data rate matches the I²C fast-mode standard, so this isolator does not introduce a throughput bottleneck on a typical sensor or memory bus. The 30kV/µs common-mode transient immunity (CMTI) is the spec that matters in motor-drive or inverter environments: fast voltage transients on the isolated side can couple across the barrier and corrupt data. A 30kV/µs rating means the part holds the data path clean through the kind of switching noise a 600V IGBT generates at turn-off. ## Six channels, three per side — channel allocation matters The part provides 3 inputs on side 1 and 3 inputs on side 2, all unidirectional. That is enough for a full I²C bus (SCL, SDA plus an interrupt or reset line) on each side, but the unidirectional nature means you cannot run a bidirectional I²C data line through a single channel without external logic. In practice, the LTM2883CY-3I#PBF handles the clock and data lines as separate unidirectional paths, which is the standard approach for isolated I²C. For industrial or automotive applications requiring -40°C to 85°C or wider, the extended-temperature suffix variants in the LTM2883 family would be the correct choice. ## 32-BGA footprint — layout considerations The 32-BGA package (15 x 11.25 mm, 1.27 mm pitch typical for this class) saves board area compared to an SOIC-wide isolator plus a separate isolated DC-DC converter. The BGA requires a solder-paste stencil and reflow profile tuned for the 0.5 mm to 0.8 mm ball diameter; hand-soldering is not practical.","metaTitle":"LTM2883CY-3I#PBF I²C Digital Isolator, 2500Vrms, 400kHz","metaDescription":"LTM2883CY-3I#PBF from Analog Devices: 6-channel I²C digital isolator with integrated isolated power, 2500Vrms isolation, 400kHz data rate, 30kV/µs CMTI.","metaKeywords":null},"attributes":{"series":"µModule®","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Digital Isolators"],"specifications":{"Type":"I²C","Series":"µModule®","Package":"Tray","Data Rate":"400kHz","Technology":"Magnetic Coupling","Channel Type":"Unidirectional","Mounting Type":"Surface Mount","Isolated Power":"Yes","Package / Case":"32-BBGA Module","lifecycle_stage":"eol_hot","Voltage - Supply":"3V ~ 3.6V","Number of Channels":"6","Voltage - Isolation":"2500Vrms","Operating Temperature":"0°C ~ 70°C","Inputs - Side 1/Side 2":"3/3","Supplier Device Package":"32-BGA (15x11.25)","Propagation Delay tpLH / tpHL (Max)":"350ns, 350ns","Common Mode Transient Immunity (Min)":"30kV/µs"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$27.43","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$27.43000","currency":"USD"},{"qty":10,"price":"$25.29500","currency":"USD"},{"qty":25,"price":"$24.15800","currency":"USD"},{"qty":119,"price":"$21.60025","currency":"USD"},{"qty":238,"price":"$20.60550","currency":"USD"},{"qty":476,"price":"$19.61076","currency":"USD"}]},"links":{"datasheetUrl":"https://www.analog.com/media/en/technical-documentation/data-sheets/2883fd.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Does LTM2883CY-3I#PBF support 400kHz I2C communication?","answer":"Yes, the part is specified for a data rate of 400kHz, which corresponds to I²C fast-mode.
