It is a general-purpose part meant to replace optocouplers and capacitive isolators in applications where data rate, isolation voltage, and common-mode transient immunity matter. With a 150 Mbps data rate, 3000 Vrms isolation, and 75 kV/µs CMTI, it handles isolated SPI, UART, and general-purpose signal isolation in industrial motor drives, power supplies, and medical equipment. ## 150 Mbps and 3 ns pulse-width distortion — timing budget matters The 150 Mbps data rate is enough for most isolated SPI buses running at 50-100 MHz clock rates, and for full-speed UART links up to 10 Mbps or more. Propagation delay is 13 ns max in both directions, with pulse-width distortion held to 3 ns. That means the part introduces minimal skew between channels and won't eat into your setup-and-hold margin on a high-speed serial link. ## 3000 Vrms and 75 kV/µs CMTI — isolation for noisy environments The 3000 Vrms isolation rating covers reinforced insulation for many industrial and medical applications. The 75 kV/µs minimum common-mode transient immunity means the part won't glitch when a motor drive or inverter switches at high dV/dt — a common failure mode with older optocouplers. If your design sees fast transients across the barrier, this part handles them cleanly. ## Supply voltage and temperature range — one rail, wide environment The 16-QSOP package (3.90 mm width) is a compact footprint for dense PCBs.","metaTitle":"ADUM142D0BRQZ-RL7 Digital Isolator, 150 Mbps, 4-Ch, 16-QSOP","metaDescription":"ADUM142D0BRQZ-RL7 is a 4-channel, 150 Mbps general-purpose digital isolator with 3000 Vrms isolation, 75 kV/µs CMTI, 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":"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":"$4.23","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":2000,"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 maximum data rate of ADUM142D0BRQZ-RL7?","answer":"The maximum data rate is 150 Mbps, which supports high-speed isolated serial interfaces like SPI and UART."},{"question":"Does ADUM142D0BRQZ-RL7 require external power?","answer":"No, it does not provide isolated power — it is a signal isolator only."},{"question":"Is ADUM142D0BRQZ-RL7 RoHS compliant?","answer":"Yes, it is ROHS3 compliant per the manufacturer's status."},{"question":"What is the difference between ADUM142D0BRQZ-RL7 and ADUM142E1BRZ-RL7?","answer":"Both are 4-channel, 150 Mbps unidirectional isolators with the same package and temperature range.
