It provides 2500Vrms isolation between input and output sides, with two channels on side 1 and two on side 2. ## 1Mbps data rate — timing budget for the bus With a maximum propagation delay of 100ns (tpLH/tpHL) and pulse width distortion of 40ns, the 1Mbps data rate supports most industrial fieldbuses and automotive CAN-like interfaces. The 2.5ns typical rise/fall time keeps edge-rate-induced ringing manageable on a 16-SOIC layout. Common-mode transient immunity of 25kV/µs minimum ensures the link stays clean in motor-drive and inverter environments where fast-switching IGBTs or SiC MOSFETs generate high dV/dt. ## Supply range and logic compatibility The unidirectional channel configuration (2 inputs on side 1, 2 outputs on side 2) is typical for isolating SPI, UART, or GPIO signals. No isolated power is generated on-chip — an external isolated DC-DC or a separate supply rail is required for the secondary side. ## Automotive grade and package Listed as Automotive grade, this part is qualified for AEC-Q100 stress tests, making it suitable for production in passenger vehicles and commercial trucks. The 16-SOIC wide-body package (7.50mm body width) provides adequate creepage for 2500Vrms isolation in high-reliability designs. Surface-mount assembly is standard;. ## Lifecycle and sourcing It is ROHS3 compliant.","metaTitle":"ADUM1402WSRWZ-RL Digital Isolator, 2500Vrms, 1Mbps, SOIC-16","metaDescription":"ADI ADUM1402WSRWZ-RL general-purpose digital isolator, 4-ch unidirectional, 2500Vrms isolation, 1Mbps data rate, -40°C to 125°C, automotive grade, SOIC-16.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Digital Isolators"],"specifications":{"Type":"General Purpose","Grade":"Automotive","Package":"Tape & Reel (TR); Cut Tape (CT)","Data Rate":"1Mbps","Technology":"Magnetic Coupling","Channel Type":"Unidirectional","Mounting Type":"Surface Mount","Isolated Power":"No","Package / Case":"16-SOIC (0.295\\\", 7.50mm Width)","lifecycle_stage":"eol_hot","Voltage - Supply":"2.7V ~ 5.5V","Number of Channels":"4","Voltage - Isolation":"2500Vrms","Operating Temperature":"-40°C ~ 125°C","Inputs - Side 1/Side 2":"2/2","Rise / Fall Time (Typ)":"2.5ns, 2.5ns","Supplier Device Package":"16-SOIC","Pulse Width Distortion (Max)":"40ns","Propagation Delay tpLH / tpHL (Max)":"100ns, 100ns","Common Mode Transient Immunity (Min)":"25kV/µs"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$8.41","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$8.41000","currency":"USD"},{"qty":10,"price":"$7.60000","currency":"USD"},{"qty":25,"price":"$7.24680","currency":"USD"},{"qty":100,"price":"$6.29230","currency":"USD"},{"qty":250,"price":"$6.00952","currency":"USD"},{"qty":500,"price":"$5.47924","currency":"USD"},{"qty":1000,"price":"$4.77225","currency":"USD"},{"qty":2000,"price":"$4.59550","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/a1ede0b49820924dd19648c8b0dbeca5.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is ADUM1402WSRWZ-RL compatible with 3.3V logic?","answer":"Yes, the 2.7V to 5.5V supply range on both sides covers 3.3V logic directly.
