The 5000 Vrms isolation rating is the headline spec for this part. It means the isolator can withstand a 5 kV potential between the two sides for 1 minute per the test standard, which covers reinforced insulation requirements in medical (IEC 60601) and industrial (IEC 61010) equipment. For a BOM decision, this rating lets you use a single isolator where a lower-rated part would need a second device or external protection to meet safety creepage. ## Bidirectional channels — no external direction pin needed I²C is an open-drain bus where both sides drive the same line low. The ADUM2250ARWZ-RL handles this with a proprietary architecture that senses the bus state and drives the output accordingly, so you don't need a separate direction-control signal or an external buffer. The two channels map to SDA and SCL, with 2 inputs on side 1 and 2 on side 2 — effectively a 2/2 configuration. The pulse width distortion is specified at 145 ns max on one channel and 85 ns on the other, which is tight enough to maintain bus timing margins at 1 Mbps even with the isolation delay. ## Common-mode transient immunity — 25 kV/µs minimum The minimum common-mode transient immunity (CMTI) of 25 kV/µs means the isolator won't glitch when a fast voltage transient slams across the isolation barrier — something that happens in motor drives with PWM switching, or in systems where the two sides power up at different rates. A lower CMTI part would risk data corruption or latch-up in those environments. This spec is a key differentiator for industrial and automotive applications where the ground potential can shift rapidly. ROHS3 compliant per the listing. If you are stocking for a long-life product, keep an eye on ADI's PCN notifications, but there is no near-term supply risk.","metaTitle":"ADUM2250ARWZ-RL I²C Digital Isolator, 5000 Vrms, 1 Mbps","metaDescription":"ADUM2250ARWZ-RL iCoupler® I²C digital isolator: 5000 Vrms isolation, 1 Mbps data rate, 2 bidirectional channels, 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","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 ADUM2250ARWZ-RL be used with a 3.3V I2C bus?","answer":"Yes.
