That 5000Vrms rating is the reinforced-isolation tier — the one you spec when the board has to survive a motor-drive short or a medical defibrillator pulse without letting the low-voltage side see the fault. The 25kV/µs common-mode transient immunity (CMTI) is the companion number: it tells you the part won't glitch or latch when a nearby IGBT switches at tens of kilovolts per microsecond. Three channels run from Side 1 to Side 2, one channel runs the other way — a 3/1 split that maps directly to a typical SPI bus (SCLK, MOSI, CS forward; MISO reverse) or a UART with flow control. ## 90Mbps data rate and the timing budget Rated for 90Mbps, with a maximum propagation delay of 32ns in either direction and a pulse-width distortion cap of 2ns. The 32ns prop delay is the budget you need to account for in your SPI clock-to-data timing or your CAN bit-timing calculation — it's not zero, and at higher data rates it eats into setup/hold margin. The 2ns pulse-width distortion means the part preserves the duty cycle well, which matters if you're passing PWM or a clock signal across the barrier. Rise and fall times are 2.5ns typical, so the edges are clean enough that you won't need a Schmitt trigger on the output unless the trace runs a long way. Operates from 3V to 5.5V on both sides — you can run the primary at 3.3V and the secondary at 5V, or any mix in between, without a separate level shifter. The 16-SOIC wide-body package (7.50mm body width) gives you the creepage distance to support the 5000Vrms rating — don't try to squeeze this into a narrow SOIC footprint; the pin spacing is part of the isolation design.","metaTitle":"ADUM4401CRWZ iCoupler Digital Isolator, 5000Vrms, 90Mbps","metaDescription":"ADUM4401CRWZ general-purpose 4-channel digital isolator: 5000Vrms isolation, 90Mbps data rate, 25kV/µs CMTI, 3V-5.5V supply, -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":"90Mbps","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":"3V ~ 5.5V","Number of Channels":"4","Voltage - Isolation":"5000Vrms","Operating Temperature":"-40°C ~ 105°C","Inputs - Side 1/Side 2":"3/1","Rise / Fall Time (Typ)":"2.5ns, 2.5ns","Supplier Device Package":"16-SOIC","Pulse Width Distortion (Max)":"2ns","Propagation Delay tpLH / tpHL (Max)":"32ns, 32ns","Common Mode Transient Immunity (Min)":"25kV/µs"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$10.34","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$10.34000","currency":"USD"},{"qty":10,"price":"$9.33700","currency":"USD"},{"qty":25,"price":"$8.90320","currency":"USD"},{"qty":100,"price":"$7.73050","currency":"USD"},{"qty":250,"price":"$7.38312","currency":"USD"},{"qty":500,"price":"$6.73164","currency":"USD"},{"qty":1000,"price":"$5.86305","currency":"USD"}]},"links":{"datasheetUrl":"https://www.analog.com/media/en/technical-documentation/data-sheets/ADuM4400_4401_4402.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is ADUM4401CRWZ unidirectional or bidirectional?","answer":"The ADUM4401CRWZ is unidirectional per channel, with a 3/1 input-side/side-2 split — three channels forward, one reverse.
