The part delivers a 150 Mbps data rate with 2.5 ns typical rise/fall times, which comfortably handles SPI, CAN FD, and high-speed UART links across the isolation barrier. ## 75 kV/µs CMTI — why it matters for motor drives and inverters The minimum common-mode transient immunity of 75 kV/µs is the standout parameter for this isolator. In a motor-drive or inverter application, the switching node of the IGBT or SiC FET can slam the ground reference of the isolated side by hundreds of volts in nanoseconds. A CMTI rating this high means the output does not glitch or lose data when that transient hits — the data sheet guarantees it. For a 3-phase inverter running at 10 kHz PWM with 600 V DC bus, this is the difference between a clean feedback signal and random bit errors on the current-sense SPI bus. ## Supply flexibility and channel assignment The channel configuration is 2 inputs on side 1 and 2 inputs on side 2 — a 2/2 split that suits bidirectional SPI (MOSI/MISO) or two pairs of isolated digital signals. Propagation delay is 13 ns max in either direction, with pulse-width distortion held to 3 ns max, keeping the duty cycle intact for PWM or timing-sensitive signals. ## Package and footprint — 16-QSOP No isolated power is generated on-chip — the part is a pure signal isolator, so each side needs its own local supply rail. ## Lifecycle and compliance It is ROHS3 compliant. The Automotive grade implies AEC-Q100 qualification, though the specific AEC-Q100 document number is not in the record; the part is intended for production automotive programs and high-reliability industrial designs.","metaTitle":"ADUM142E1WBRQZ-RL7 Digital Isolator, 150Mbps, 4Ch, 16-QSOP","metaDescription":"ADUM142E1WBRQZ-RL7 automotive-grade 4-channel digital isolator with magnetic coupling, 150Mbps data rate, 3000Vrms isolation, and 75kV/µs CMTI.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Digital Isolators"],"specifications":{"Type":"General Purpose","Grade":"Automotive","Package":"Tape & Reel (TR); Cut Tape (CT)","Data Rate":"150Mbps","Technology":"Magnetic Coupling","Channel Type":"Unidirectional","Mounting Type":"Surface Mount","Isolated Power":"No","Package / Case":"16-SSOP (0.154\\\", 3.90mm Width)","lifecycle_stage":"eol_hot","Voltage - Supply":"1.7V ~ 5.5V","Number of Channels":"4","Voltage - Isolation":"3000Vrms","Operating Temperature":"-40°C ~ 125°C","Inputs - Side 1/Side 2":"2/2","Rise / Fall Time (Typ)":"2.5ns, 2.5ns","Supplier Device Package":"16-QSOP","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":"$4.68","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$4.68000","currency":"USD"},{"qty":10,"price":"$4.20700","currency":"USD"},{"qty":25,"price":"$3.97680","currency":"USD"},{"qty":100,"price":"$3.44660","currency":"USD"},{"qty":250,"price":"$3.26988","currency":"USD"},{"qty":500,"price":"$2.93404","currency":"USD"},{"qty":1000,"price":"$2.47450","currency":"USD"},{"qty":2000,"price":"$2.35078","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 closest pin-compatible alternative to ADUM142E1WBRQZ-RL7?","answer":"The ADUM142E1WBRQZ-RL7 is a specific channel-configuration and speed-grade variant in the ADuM14xE1W family.
