It delivers a 150 Mbps data rate with 13 ns typical propagation delay and 3 ns pulse-width distortion, making it suitable for high-speed SPI buses in automotive and industrial environments. The 3750 VDC isolation rating and 100 kV/µs common-mode transient immunity (CMTI) are sized for motor-drive feedback, inverter gate-drive interfaces, and battery-management communication links where fast transients and galvanic isolation are required. ## 125°C operating range and automotive qualification The Automotive grade designation means it carries the AEC-Q100 qualification and PPAP documentation expected for production vehicle programs. For designs that need the same isolation performance at a lower CMTI threshold, the ADUM142E1BRZ-RL7 (75 kV/µs) is a commercial-grade alternative, but the WBRWZ suffix on this seed part is the one to specify when the BOM calls for automotive traceability. ## Supply range and channel direction for SPI buses The 2/2 input split (two inputs on side 1, two on side 2) maps directly to a standard SPI interface: one channel for SCK, one for MOSI on the controller side, and two for MISO and a chip-select or interrupt on the peripheral side. Rise and fall times are 2.5 ns typical, so signal integrity on the 16-SOIC footprint needs attention to trace impedance and decoupling — the 7.50 mm wide body gives good pin-to-pin creepage for the 3750 VDC isolation rating.","metaTitle":"ADUM142E1WBRWZ-RL Digital Isolator, 150Mbps, 4CH SPI","metaDescription":"ADI ADUM142E1WBRWZ-RL automotive-grade digital isolator: 150Mbps SPI, 3750VDC isolation, 100kV/µs CMTI, -40°C to 125°C, 16-SOIC.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Digital Isolators"],"specifications":{"Type":"SPI","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-SOIC (0.295\\\", 7.50mm Width)","lifecycle_stage":"eol_hot","Voltage - Supply":"1.8V ~ 5.5V","Number of Channels":"4","Voltage - Isolation":"3750VDC","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-SOIC","Pulse Width Distortion (Max)":"3ns","Propagation Delay tpLH / tpHL (Max)":"13ns, 13ns","Common Mode Transient Immunity (Min)":"100kV/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":"Is ADUM142E1WBRWZ-RL automotive grade?","answer":"Yes, this part is listed with an Automotive grade, meaning it is AEC-Q100 qualified and suitable for automotive applications including under-hood and chassis domains."},{"question":"What is the maximum data rate of ADUM142E1WBRWZ-RL?","answer":"The maximum data rate is 150 Mbps, with a propagation delay of 13 ns max and pulse-width distortion of 3 ns max.
