At 25Mbps, this part handles most industrial serial links — SPI clocks up to 25 MHz, UART at standard baud rates, and parallel GPIO handshake lines. The 60ns max propagation delay (tpLH/tpHL) and 6ns max pulse-width distortion mean the signal edge timing stays tight enough that a 25 MHz SPI bus won't lose setup/hold margin across the isolation barrier. Rise and fall times are 2.5ns typical, so the output slew rate is fast — the 16-SOIC footprint keeps the trace short, but if the isolated side drives a long cable, a series resistor at the output may be needed to damp ringing. The 25kV/µs minimum common-mode transient immunity (CMTI) is the spec that matters in motor-drive or inverter environments: it guarantees the data link won't glitch when a 1kV/µs or faster common-mode step slams across the barrier. ## Supply range and isolated power — design-in checklist The ADUM5402CRWZ operates from a single 3V to 5.5V supply on the primary side; the integrated IsoPower converter generates the isolated secondary-side rail internally. That means the design only needs one regulated input rail — no separate isolated DC-DC, no transformer, no secondary-side regulator. The output power from the IsoPower converter is limited (typically tens of milliamps at 5V), so the secondary side can power the isolator's own output buffers and a small external load like a transceiver or a low-power sensor, but not a relay coil or a high-current peripheral. If the secondary-side current budget is tight, the 3V to 5.5V supply range lets you run both sides at 3.3V or 5V, matching common logic families without level shifters. ## Temperature grade and package — where it fits The 16-SOIC (7.50mm width) body is a standard footprint — no special pad pattern beyond the usual SOIC-16 land. The wider body (300 mil vs the narrow 150 mil) helps with creepage distance across the PCB for the 2500Vrms isolation rating.","metaTitle":"ADUM5402CRWZ Digital Isolator, 2500Vrms, 25Mbps, IsoPower","metaDescription":"ADUM5402CRWZ general-purpose digital isolator with integrated isolated power. 4 unidirectional channels, 2500Vrms 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":"Tube","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":"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)":"6ns","Propagation Delay tpLH / tpHL (Max)":"60ns, 60ns","Common Mode Transient Immunity (Min)":"25kV/µs"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$14.55","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$14.55000","currency":"USD"},{"qty":10,"price":"$13.37200","currency":"USD"},{"qty":25,"price":"$12.81800","currency":"USD"},{"qty":100,"price":"$11.29360","currency":"USD"},{"qty":250,"price":"$10.73932","currency":"USD"},{"qty":500,"price":"$10.04648","currency":"USD"},{"qty":1000,"price":"$9.21504","currency":"USD"}]},"links":{"datasheetUrl":"https://www.analog.com/media/en/technical-documentation/data-sheets/ADuM5401_5402_5403_5404.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Can ADUM5402CRWZ provide isolated power?","answer":"Yes. The ADUM5402CRWZ integrates an IsoPower DC-DC converter that generates an isolated output voltage on the secondary side, eliminating the need for a separate isolated DC-DC module. The available output current is limited — typically sufficient to power the isolator's own secondary-side circuitry and a small external load such as a transceiver or low-power sensor, but not a high-current device."},{"question":"Is ADUM5402CRWZ compatible with 3.3V systems?","answer":"Yes. The supply voltage range is 3V to 5.5V, so the primary side can run at 3.3V. The secondary-side output from the IsoPower converter is also regulated within that range, typically set to match the primary supply voltage. Both sides operate at the same logic levels, so no level shifting is needed when interfacing with 3.3V MCUs or FPGAs."},{"question":"What are the alternatives to ADUM5402CRWZ?","answer":"The ADUM6400CRWZ offers four forward-only channels (4/0 input split) with 5000Vrms isolation in the same package.
