The 10 Mbps data rate covers common interfaces like SPI (up to 10 MHz clock), UART, and general-purpose GPIO isolation without stretching the timing budget. ## 25 kV/µs transient immunity — keeps data clean in noisy environments A minimum common-mode transient immunity of 25 kV/µs means the ADUM3400BRWZ can reject fast voltage spikes between its ground domains — the kind of noise you get from a switching MOSFET in a motor drive, an inverter leg, or a flyback converter. If the isolation barrier sees a 25 kV/µs or slower common-mode step, the output stays valid. That spec is the difference between a clean data stream and bit errors on the factory floor. ## Propagation delay and pulse-width distortion Maximum propagation delay is 50 ns in either direction, and pulse-width distortion is held to 3 ns max. For a 10 Mbps signal with a 100 ns bit period, 50 ns of delay is half a bit time — enough to matter if you are daisy-chaining multiple isolators in a timing-critical path. The 3 ns pulse-width distortion means the on and off delays are closely matched, so duty cycle is preserved within a few percent at 10 Mbps. Rise and fall times are a typical 2.5 ns, keeping the edges sharp enough for clean clock recovery. The wide-body SOIC-16 package provides the creepage distance needed to maintain 2500 Vrms isolation in high-humidity or polluted conditions. ## Active production and compliance No lead-free exemption issues to track for a long-life BOM.","metaTitle":"ADUM3400BRWZ iCoupler Digital Isolator, 10 Mbps, 2500 Vrms","metaDescription":"ADUM3400BRWZ general-purpose digital isolator: 10 Mbps data rate, 2500 Vrms isolation, 4 unidirectional channels, -40°C to 105°C, SOIC-16.","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":"3V ~ 5.5V","Number of Channels":"4","Voltage - Isolation":"2500Vrms","Operating Temperature":"-40°C ~ 105°C","Inputs - Side 1/Side 2":"4/0","Rise / Fall Time (Typ)":"2.5ns, 2.5ns","Supplier Device Package":"16-SOIC","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":"$6.78","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$6.78000","currency":"USD"},{"qty":10,"price":"$6.12400","currency":"USD"},{"qty":25,"price":"$5.83880","currency":"USD"},{"qty":100,"price":"$5.06980","currency":"USD"},{"qty":250,"price":"$4.84192","currency":"USD"},{"qty":500,"price":"$4.41472","currency":"USD"},{"qty":1000,"price":"$3.84507","currency":"USD"},{"qty":2500,"price":"$3.70266","currency":"USD"}]},"links":{"datasheetUrl":"https://www.analog.com/media/en/technical-documentation/data-sheets/ADUM3400_3401_3402.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the data rate of ADUM3400BRWZ?","answer":"The ADUM3400BRWZ supports a data rate of 10 Mbps, which is sufficient for isolating SPI at up to 10 MHz, UART at standard baud rates, and general-purpose digital signals."},{"question":"Is ADUM3400BRWZ RoHS compliant or lead-free?","answer":"Yes, the ADUM3400BRWZ is ROHS3 compliant, meaning it meets the current RoHS directive without any exempted lead content."},{"question":"Can ADUM3400BRWZ be used for I2C isolation?","answer":"The ADUM3400BRWZ has four unidirectional channels, all with inputs on side 1. I2C is a bidirectional bus requiring a bidirectional isolator or a unidirectional part with external circuitry to handle the data direction reversal.
