It provides 5000Vrms isolation between the bus sides, with one bidirectional channel (SCL/SDA) and one unidirectional channel, supporting data rates up to 1Mbps. The supply range spans 3V to 5.5V on each side, making it compatible with both 3.3V and 5V I²C buses without level translation. ## Industrial temperature and package fit The 16-SOIC wide-body package (7.50mm width) provides the creepage distance needed for the 5000Vrms rating. Surface-mount assembly with standard SOIC-16 footprint. ## Common-mode transient immunity and pulse width distortion With a minimum common-mode transient immunity of 25kV/µs, the isolator maintains data integrity in noisy switching environments — relevant when the bus runs near motor drives or SMPS stages. Pulse width distortion is specified at 145ns (bidirectional channel) and 85ns (unidirectional channel), which sets the timing margin for the I²C clock stretching and arbitration logic. For production BOMs this means no forced redesign horizon from obsolescence, though I²C isolator demand has been steady through the cycle — allocation risk is low but not zero if your volume spikes.","metaTitle":"ADUM2251ARWZ I²C Digital Isolator, 5000Vrms, 1Mbps","metaDescription":"ADUM2251ARWZ iCoupler I²C digital isolator, 5000Vrms isolation, 1Mbps data rate, 2 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":"Tube","Data Rate":"1Mbps","Technology":"Magnetic Coupling","Channel Type":"Bidirectional, Unidirectional","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":"2/1","Supplier Device Package":"16-SOIC","Pulse Width Distortion (Max)":"145ns, 85ns","Common Mode Transient Immunity (Min)":"25kV/µs"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$8.65","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$8.65000","currency":"USD"},{"qty":10,"price":"$7.81700","currency":"USD"},{"qty":25,"price":"$7.45360","currency":"USD"},{"qty":100,"price":"$6.47210","currency":"USD"},{"qty":250,"price":"$6.18120","currency":"USD"},{"qty":500,"price":"$5.63580","currency":"USD"},{"qty":1000,"price":"$4.90860","currency":"USD"}]},"links":{"datasheetUrl":"https://www.analog.com/media/en/technical-documentation/data-sheets/ADuM2250_ADuM2251.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Can ADUM2251ARWZ be used with 5V I2C?","answer":"Yes.
