The channel configuration is 2 inputs on side 1 and 2 inputs on side 2, making it suited for isolating two bidirectional signal pairs or a mix of control and data lines in industrial interfaces. At 1 Mbps, this part handles standard SPI (up to 1 MHz clock), UART at 115200 baud with margin, and slow I²C (100 kHz). If your link needs 10 Mbps or faster (e.g., high-speed SPI for ADC reads), this is not the right isolator — look at the ADuM140x series with higher data rate options. The 100 ns max propagation delay (both directions) adds about one clock cycle of latency at 10 MHz, so budget that into your timing closure. ## Isolation and transient immunity for motor-drive environments Rated at 2500 Vrms isolation, this part meets basic insulation for 240 VAC mains interfaces in industrial equipment. More critical for motor-drive or inverter applications is the 25 kV/µs minimum common-mode transient immunity — that rating says the data link will not glitch when a nearby IGBT switches 600 V in 50 ns. Pair it with a clean local supply decoupling (100 nF ceramic at each supply pin) to keep the internal coupling coils from coupling supply noise into the data path. ## Temperature grade and deployment context No AEC-Q100 qualification is listed, so this part is not certified for automotive use under hood or in cabin. For automotive-grade isolation, look at the ADuM140xW variants with AEC-Q100 grade-1 rating.","metaTitle":"ADUM1402ARWZ iCoupler Digital Isolator, 1Mbps, 2500Vrms","metaDescription":"ADUM1402ARWZ magnetic-coupling digital isolator, 4 channels, 1Mbps, 2500Vrms isolation, -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":"Tube","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 ~ 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":"$6.44","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$6.44000","currency":"USD"},{"qty":10,"price":"$5.82000","currency":"USD"},{"qty":47,"price":"$5.54894","currency":"USD"},{"qty":141,"price":"$4.81809","currency":"USD"},{"qty":282,"price":"$4.60156","currency":"USD"},{"qty":517,"price":"$4.19553","currency":"USD"},{"qty":1034,"price":"$3.65418","currency":"USD"},{"qty":2538,"price":"$3.51884","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/a1ede0b49820924dd19648c8b0dbeca5.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the data rate of ADUM1402ARWZ?","answer":"The data rate is 1 Mbps, with a maximum propagation delay of 100 ns in both directions."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/ADUM1402ARWZ","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/ADUM1402ARWZ when reusing this data.
