Data rate is rated at 10Mbps, which comfortably handles most serial protocols up to full-speed SPI without timing margin issues. Propagation delay is 50ns max (both directions), and pulse-width distortion holds to 3ns max — tight enough for synchronous interfaces where skew between channels matters. Supply voltage spans 2.7V to 5.5V on both sides, so it can bridge 3.3V and 5V logic domains without a separate level shifter. The wide range also helps during power-up sequencing: either side can come up first without latch-up or excessive current draw. ## 25kV/µs CMTI — why it matters for motor drives and inverters Common-mode transient immunity is rated at 25kV/µs minimum. In a variable-frequency drive, the IGBT switching edges can slam several hundred volts across the isolation barrier in a few nanoseconds. If the isolator's CMTI is too low, those edges couple through as data errors or latch-up. At 25kV/µs the ADUM2402BRIZ handles the typical 600V/µs to 1500V/µs transients in industrial drives with margin to spare. Rise and fall times are 2.5ns typical — fast enough to preserve signal integrity at 10Mbps but not so fast that they radiate excessively. Pair with a solid ground plane under the SOIC and a 100nF decoupling cap per supply pin, as close as the layout allows. ## Channel configuration and temperature range Four unidirectional channels are arranged as two inputs on side 1 and two inputs on side 2. That split suits half-duplex interfaces (e.g., RS-485 with separate DE and RE) or mixed-direction sensor isolation where a few signals need to cross the barrier in each direction. No isolated power is integrated — each side needs its own supply rail.","metaTitle":"ADUM2402BRIZ iCoupler Digital Isolator, 5000Vrms, 10Mbps","metaDescription":"ADUM2402BRIZ general-purpose 4-channel digital isolator with 5000Vrms isolation, 10Mbps data rate, 25kV/µs CMTI. -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":"10Mbps","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-IC","Pulse Width Distortion (Max)":"3ns","Propagation Delay tpLH / tpHL (Max)":"50ns, 50ns","Common Mode Transient Immunity (Min)":"25kV/µs"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$9.86","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$9.86000","currency":"USD"},{"qty":10,"price":"$8.90300","currency":"USD"},{"qty":25,"price":"$8.48920","currency":"USD"},{"qty":100,"price":"$7.37100","currency":"USD"},{"qty":250,"price":"$7.03968","currency":"USD"},{"qty":500,"price":"$6.41856","currency":"USD"},{"qty":1000,"price":"$5.59035","currency":"USD"}]},"links":{"datasheetUrl":"https://www.analog.com/media/en/technical-documentation/data-sheets/ADuM2400_2401_2402.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is ADUM2402BRIZ unidirectional or bidirectional?","answer":"The ADUM2402BRIZ is a unidirectional isolator.
