All four channels run in the same direction (Side 1 to Side 2), so it is a straight drop-in for isolating a 4-bit parallel bus, SPI signals (SCLK, MOSI, MISO, CS), or a set of GPIO lines where the data flow is one-way. The 10 Mbps data rate handles most industrial fieldbus and sensor interfaces comfortably — the 50 ns propagation delay per edge keeps timing margin on a 10 MHz SPI clock without needing a faster (and pricier) isolator. ## 2500 Vrms isolation — what it buys you Rated at 2500 Vrms for one minute, this part provides basic isolation for equipment connected to the same ground reference but needing protection against ground loops, transient spikes, or fault conditions. It is not a reinforced-isolation part for mains-connected medical or grid-tied power supplies (those typically need 5000 Vrms or higher). Where it fits: isolating the control-side MCU from a motor-drive gate driver, separating the sensor interface in a PLC input module, or breaking a ground loop between two boards sharing a backplane. The 25 kV/µs common-mode transient immunity means it holds up in noisy switching environments — a VFD or inverter bus with fast IGBT edges will not glitch the data. The wide-body SOIC-16 package (7.50 mm body width) gives the creepage distance needed for the 2500 Vrms rating; standard SOIC-8 or SOIC-16 narrow-body parts cannot match the isolation voltage. ## Lifecycle and compliance The iCoupler series has been in production for years;.","metaTitle":"ADUM1400BRWZ iCoupler Digital Isolator, 10 Mbps, 2500 Vrms","metaDescription":"ADUM1400BRWZ from Analog Devices: 4-channel unidirectional digital isolator, 10 Mbps data rate, 2500 Vrms isolation, -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":"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":"$7.4","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$7.40000","currency":"USD"},{"qty":10,"price":"$6.68800","currency":"USD"},{"qty":25,"price":"$6.37720","currency":"USD"},{"qty":100,"price":"$5.53720","currency":"USD"},{"qty":250,"price":"$5.28836","currency":"USD"},{"qty":500,"price":"$4.82174","currency":"USD"},{"qty":1000,"price":"$4.19958","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/a1ede0b49820924dd19648c8b0dbeca5.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the difference between ADUM1400 and ADUM1401?","answer":"The ADUM1400 has all four channels in the same direction (Side 1 to Side 2). The ADUM1401 reverses one channel (three forward, one reverse) for bidirectional isolation.
