Its two bidirectional channels handle the clock and data lines natively — no external direction-control logic or extra GPIO toggling, which is the trap engineers hit when they try to use a unidirectional digital isolator on an I²C link. The part integrates the open-drain bus buffers and the isolation barrier into one 16-SOIC package, rated for 5000Vrms of galvanic isolation. The 5000Vrms isolation voltage qualifies this part for reinforced insulation in mains-connected equipment — think motor drives, industrial PLCs, and medical power supplies where the I²C bus crosses a safety barrier. The 25kV/µs common-mode transient immunity means the data stays clean when a 600V MOSFET switches next to the isolator; in a noisy inverter cabinet, that spec is what prevents bit errors on the bus. ## Supply range and data rate — fits 3.3V and 5V buses The supply range of 3V to 5.5V lets you run the isolator on either a 3.3V or 5V I²C bus without a level shifter — the side-1 and side-2 supplies are independent, so you can bridge a 3.3V controller to a 5V sensor node. The 1Mbps data rate covers standard-mode (100kHz) and fast-mode (400kHz) I²C with margin; it will not limit a typical sensor or EEPROM bus. ## Temperature grade and package The 16-SOIC-IC package is the wide-body 7.50mm width, which gives the creepage distance needed to sustain the 5000Vrms rating across the isolation barrier. ## Lifecycle and sourcing For dual-sourcing or a unidirectional variant, the ADUM2251ARWZ offers a 2/1 input split (one channel bidirectional, one unidirectional) in the same package — useful if your design only needs one bidirectional I²C channel and a general-purpose isolated signal.","metaTitle":"ADUM2250ARIZ-RL I2C Digital Isolator, 5000Vrms, 1Mbps","metaDescription":"ADUM2250ARIZ-RL iCoupler I2C isolator: 5000Vrms isolation, 1Mbps data rate, bidirectional 2-channel, 3V-5.5V supply, -40°C to 105°C.","metaKeywords":null},"attributes":{"series":"iCoupler®","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Digital Isolators"],"specifications":{"Type":"I²C","Series":"iCoupler®","Package":"Tape & Reel (TR); Cut Tape (CT)","Data Rate":"1Mbps","Technology":"Magnetic Coupling","Channel Type":"Bidirectional","Mounting Type":"Surface Mount","Isolated Power":"No","Package / Case":"16-SOIC (0.295\\\", 7.50mm Width)","lifecycle_stage":"eol_hot","Voltage - Supply":"3V ~ 5.5V","Number of Channels":"2","Voltage - Isolation":"5000Vrms","Operating Temperature":"-40°C ~ 105°C","Inputs - Side 1/Side 2":"2/2","Supplier Device Package":"16-SOIC-IC","Pulse Width Distortion (Max)":"145ns, 85ns","Common Mode Transient Immunity (Min)":"25kV/µs"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$9.33","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$9.33000","currency":"USD"},{"qty":10,"price":"$8.42500","currency":"USD"},{"qty":25,"price":"$8.03360","currency":"USD"},{"qty":100,"price":"$6.97550","currency":"USD"},{"qty":250,"price":"$6.66196","currency":"USD"},{"qty":500,"price":"$6.07414","currency":"USD"},{"qty":1000,"price":"$5.29038","currency":"USD"}]},"links":{"datasheetUrl":"https://www.analog.com/media/en/technical-documentation/data-sheets/ADuM2250_ADuM2251.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Can ADUM2250ARIZ-RL operate at 3.3V?","answer":"Yes.
