Its headline rating is 5000Vrms isolation in a 16-SOIC wide-body package — a reinforced insulation class that suits medical patient-contact interfaces, industrial motor-drive feedback paths, and grid-tied power converters where the isolation barrier must survive transient overvoltages without breakdown. The 1Mbps data rate is deliberate: this is the throughput tier for isolated UART, I²C, or slow SPI buses, not high-speed isolated Ethernet or USB. If your design needs 10Mbps or faster, you are looking at a different iCoupler variant (ADUM140x series with higher speed grades). ## Channel count and direction — 2/2 split for unidirectional isolation Four unidirectional channels split 2/2 across the isolation barrier (two from Side 1 to Side 2, two from Side 2 to Side 1). This fixed direction matters: unlike the ADUM2400 series (all same-direction), the ADUM2402 lets you isolate a bidirectional data bus without external direction-control logic. The 2.7V to 5.5V supply range on both sides means the part works in mixed-voltage domains — a 3.3V MCU talking to a 5V sensor, for example — without a separate level shifter. ## Timing margins for the bus Propagation delay is 100ns max (both directions), with pulse-width distortion capped at 40ns. At 1Mbps (1µs bit period), the 100ns delay consumes 10% of the bit time — acceptable for most UART and I²C links, but tight for a daisy-chained SPI bus with multiple isolators in series. The 2.5ns rise/fall times are fast enough to avoid slew-rate limiting at 1Mbps, but the 25kV/µs common-mode transient immunity (minimum) is the spec that matters for motor-drive or inverter environments where high dV/dt on the ground plane can couple through the barrier. If your system sees >25kV/µs common-mode edges, you need a reinforced or capacitive-coupling isolator rated higher. For a production BOM, this is the low-risk choice — you are not chasing surplus lots or date-code windows.","metaTitle":"ADUM2402ARWZ-RL Digital Isolator, 5000Vrms, 4-Ch, 1Mbps","metaDescription":"ADUM2402ARWZ-RL iCoupler 4-channel digital isolator with 5000Vrms isolation, 1Mbps data rate, unidirectional, -40°C to 105°C.","metaKeywords":null},"attributes":{"series":"iCoupler®","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Digital Isolators"],"specifications":{"Type":"General Purpose","Series":"iCoupler®","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":"5000Vrms","Operating Temperature":"-40°C ~ 105°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":"$8.82","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$8.82000","currency":"USD"},{"qty":10,"price":"$7.96900","currency":"USD"},{"qty":25,"price":"$7.59880","currency":"USD"},{"qty":100,"price":"$6.59790","currency":"USD"},{"qty":250,"price":"$6.30140","currency":"USD"},{"qty":500,"price":"$5.74538","currency":"USD"},{"qty":1000,"price":"$5.00404","currency":"USD"},{"qty":2000,"price":"$4.81871","currency":"USD"}]},"links":{"datasheetUrl":"https://www.analog.com/media/en/technical-documentation/data-sheets/ADuM2400_2401_2402.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What are the alternatives to ADUM2402ARWZ-RL?","answer":"Within the iCoupler family, the ADUM2400 series offers four same-direction channels (all inputs on one side), while the ADUM2401 provides a 3/1 split.
