The 75 kV/µs common-mode transient immunity (CMTI) means it holds its data integrity through fast-switching inverter edges and motor-drive noise — a spec that matters more than the raw data rate when the board shares a ground with a VFD or a half-bridge. ## All four inputs on one side — routing simplicity Channel configuration is 4 inputs on side 1, 0 on side 2, all unidirectional. That means the isolator passes four signals in one direction only — typical for an isolated SPI bus (SCLK, MOSI, CS, and a data-ready line) or a set of GPIOs from a controller to a remote ADC or DAC. No bidirectional channels to manage, no direction-control pin to toggle. ## Propagation delay and timing margin Max propagation delay is 13 ns in both directions, with a 3 ns pulse-width distortion. Rise and fall times are 2.5 ns typical. ## Temperature range and environments The 125°C ceiling means it survives next to a hot power stage or inside a sealed enclosure without derating the isolation voltage.","metaTitle":"ADUM140D1BRWZ iCoupler Digital Isolator, 150 Mbps, 3750 Vrms","metaDescription":"ADUM140D1BRWZ 4-channel unidirectional digital isolator with 150 Mbps data rate, 3750 Vrms isolation, 75 kV/µs CMTI, -40°C to 125°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":"150Mbps","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":"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":"What is the difference between ADUM140D1BRWZ and ADUM140D0BRWZ?","answer":"The ADUM140D1BRWZ has all four inputs on side 1 (4/0 channel configuration), while the ADUM140D0BRWZ has all four inputs on side 2 (0/4).
