It provides 5000Vrms galvanic isolation across four unidirectional channels — two from Side 1 to Side 2, two from Side 2 to Side 1 — using magnetic coupling technology. The built-in IsoPower regulator generates a regulated output voltage on the isolated side from the 3V to 5.5V input supply, eliminating the need for a separate isolated power module. This part is designed for general-purpose isolation in industrial fieldbus interfaces, motor-drive control signals, medical equipment isolation barriers, and any application where a compact, certified isolation solution with integrated power saves board space and BOM cost. The 5000Vrms isolation voltage rating qualifies this part for reinforced insulation in medical (IEC 60601) and industrial (IEC 61010) applications where a single-fault condition must not create a safety hazard. The 25kV/µs common-mode transient immunity means the output logic state holds steady when a fast high-voltage transient — like the switching edge in a motor-drive inverter or a lightning surge on a field cable — slams the isolation barrier. In practice, this CMTI number keeps the data link from bit-flipping in noisy environments where a lower-rated isolator would glitch. ## 25Mbps data rate and propagation delay — sizing the timing budget The 25Mbps data rate supports SPI clocks up to 12.5 MHz (half-duplex), UART at standard baud rates, and general-purpose GPIO isolation. The maximum propagation delay of 60ns in either direction and pulse-width distortion of 6ns are tight enough that a 25Mbps NRZ signal retains adequate eye opening across the barrier. If your bus runs faster than 25Mbps — say, a 50 MHz SPI — this part will not close timing; step up to a higher-rate isolator family. ## Package and footprint — 16-SOIC wide-body The wide-body gives the creepage distance needed to sustain the 5000Vrms rating — standard SOIC-16 narrow (3.90 mm) would not pass. Surface-mount assembly with standard reflow profiles works; the package is MSL-rated per the datasheet. The Tape & Reel suffix (-RL) means it ships on 13-inch reels, typical for volume production. ## Temperature range and operating environment If your application requires 125°C ambient (under-hood automotive, downhole tools), the ADUM5402WCRWZ-1RL carries an automotive-grade variant with the same 25Mbps data rate but lower 2500Vrms isolation.","metaTitle":"ADUM6402CRWZ-RL Digital Isolator, 5000Vrms, 25Mbps, 4-Ch","metaDescription":"ADUM6402CRWZ-RL quad-channel digital isolator with integrated IsoPower isolated DC-DC converter. 5000Vrms isolation, 25Mbps data rate, -40°C to 105°C.","metaKeywords":null},"attributes":{"series":"IsoPower®, iCoupler®","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Digital Isolators"],"specifications":{"Type":"General Purpose","Series":"IsoPower®, iCoupler®","Package":"Tape & Reel (TR); Cut Tape (CT)","Data Rate":"25Mbps","Technology":"Magnetic Coupling","Channel Type":"Unidirectional","Mounting Type":"Surface Mount","Isolated Power":"Yes","Package / Case":"16-SOIC (0.295\\\", 7.50mm Width)","lifecycle_stage":"eol_hot","Voltage - Supply":"3V ~ 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)":"6ns","Propagation Delay tpLH / tpHL (Max)":"60ns, 60ns","Common Mode Transient Immunity (Min)":"25kV/µs"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$17.18","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$17.18000","currency":"USD"},{"qty":10,"price":"$15.78900","currency":"USD"},{"qty":25,"price":"$15.13480","currency":"USD"},{"qty":100,"price":"$13.33500","currency":"USD"},{"qty":250,"price":"$12.68056","currency":"USD"},{"qty":500,"price":"$11.86244","currency":"USD"},{"qty":1000,"price":"$10.88073","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/64cbf3e9142c9771c928705455ac2af4.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the difference between ADUM6402CRWZ-RL and ADUM6400CRWZ?","answer":"Both are quad-channel IsoPower isolators with 5000Vrms isolation and 25Mbps data rate.
