Its 3750 Vrms isolation rating suits it for breaking ground loops and providing safety isolation in industrial interfaces. The 2 Mbps data rate handles most UART and low-speed SPI links. ## Active lifecycle — no last-time-buy scramble ADI lists the ADUM1241ARSZ as Active. That means you can plan multi-year production runs without worrying about a forced last-time-buy window. ## Package and temperature — shelf and board fit Housed in a 20-lead SSOP (5.30 mm body width), surface-mount only. Store the reels dry — SSOP packages are MSL-sensitive, and a bake cycle before reflow adds a day to the build if the moisture barrier bag has been open past the floor-life window.","metaTitle":"ADUM1241ARSZ iCoupler Digital Isolator, 3750Vrms, 2Mbps","metaDescription":"ADUM1241ARSZ general-purpose digital isolator from ADI's iCoupler series.","metaKeywords":null},"attributes":{"series":"iCoupler®","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Digital Isolators"],"specifications":{"Type":"General Purpose","Series":"iCoupler®","Package":"Tube","Data Rate":"2Mbps","Technology":"Magnetic Coupling","Channel Type":"Unidirectional","Mounting Type":"Surface Mount","Isolated Power":"No","Package / Case":"20-SSOP (0.209\\\", 5.30mm Width)","lifecycle_stage":"eol_hot","Voltage - Supply":"2.25V ~ 3.6V","Number of Channels":"2","Voltage - Isolation":"3750Vrms","Operating Temperature":"-40°C ~ 125°C","Inputs - Side 1/Side 2":"1/1","Rise / Fall Time (Typ)":"2ns, 2ns","Supplier Device Package":"20-SSOP","Pulse Width Distortion (Max)":"8ns","Propagation Delay tpLH / tpHL (Max)":"180ns, 180ns","Common Mode Transient Immunity (Min)":"25kV/µs"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$5.03","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$5.03000","currency":"USD"},{"qty":10,"price":"$4.51900","currency":"USD"},{"qty":25,"price":"$4.27240","currency":"USD"},{"qty":100,"price":"$3.70270","currency":"USD"},{"qty":250,"price":"$3.51280","currency":"USD"},{"qty":500,"price":"$3.15200","currency":"USD"},{"qty":1000,"price":"$2.65832","currency":"USD"},{"qty":2500,"price":"$2.52540","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/4aefb66043e54be1d6472f25241387f6.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Can ADUM1241ARSZ be used for I2C isolation?","answer":"The ADUM1241ARSZ has unidirectional channels (1/1 configuration), so it cannot directly handle the bidirectional SDA line of I2C without external circuitry.
