It delivers 150 Mbps per channel with 3750 Vrms isolation, making it a fit for high-speed signal isolation in industrial fieldbuses, motor-drive feedback, and isolated SPI/UART links. ## 75 kV/µs CMTI — why it matters for motor drives and inverters Common-mode transient immunity is rated at 75 kV/µs minimum. In a motor-drive or inverter application, the switching node slews at tens of kV/µs; a CMTI below that threshold can couple the transient across the barrier and corrupt the data. This part's 75 kV/µs rating gives margin for most SiC and GaN gate-drive stages running at moderate switching speeds. ## Propagation delay and pulse-width distortion — timing budget for high-speed links Maximum propagation delay is 13 ns in both directions, with pulse-width distortion capped at 3 ns. Budget for it in the link timing closure. ## 4/0 channel configuration — all inputs on one side The channel assignment is 4 inputs on Side 1, 0 on Side 2 — all four channels run in the same direction. That suits unidirectional data paths like SPI (SCLK, MOSI, CS, and a fourth signal) or parallel control lines from a controller to a peripheral. For bidirectional links you would need a part with channels in both directions, such as the ADUM140D1BRZ (3/1 split) or a two-device solution. ## Package and supply — design-in notes Housed in a 16-SOIC narrow-body (3.90 mm width) package, surface-mount. No isolated power output — each side needs its own supply rail.","metaTitle":"ADUM140D0BRZ iCoupler Digital Isolator, 150 Mbps, 3750 Vrms","metaDescription":"ADUM140D0BRZ general-purpose 4-channel digital isolator with 150 Mbps data rate, 3750 Vrms isolation, and -40°C to 125°C range.","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":"150Mbps","Technology":"Magnetic Coupling","Channel Type":"Unidirectional","Mounting Type":"Surface Mount","Isolated Power":"No","Package / Case":"16-SOIC (0.154\\\", 3.90mm Width)","lifecycle_stage":"eol_hot","Voltage - Supply":"1.7V ~ 5.5V","Number of Channels":"4","Voltage - Isolation":"3750Vrms","Operating Temperature":"-40°C ~ 125°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)":"13ns, 13ns","Common Mode Transient Immunity (Min)":"75kV/µs"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$4.23","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$4.23000","currency":"USD"},{"qty":10,"price":"$3.79800","currency":"USD"},{"qty":25,"price":"$3.59040","currency":"USD"},{"qty":100,"price":"$3.11180","currency":"USD"},{"qty":250,"price":"$2.95224","currency":"USD"},{"qty":500,"price":"$2.64902","currency":"USD"},{"qty":1000,"price":"$2.23412","currency":"USD"},{"qty":2500,"price":"$2.12242","currency":"USD"}]},"links":{"datasheetUrl":"https://www.analog.com/media/en/technical-documentation/data-sheets/ADuM140D_140E_141D_141E_142D_142E.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Does ADUM140D0BRZ require an external isolated power supply?","answer":"Yes.
