Product details
Overview
ADUM142D0BRWZ from Analog Devices is a quad-channel digital isolator based on iCoupler® technology, providing galvanic isolation between microcontroller peripherals and high-noise industrial buses. It delivers 3.75 kVRMS withstand voltage, 150 Mbps guaranteed data rate, 15 ns max propagation delay at 1.8 V, and operates across 1.8 V to 5 V supply rails with level translation capability. It is used in isolated SPI interfaces for motor drives and PLC I/O modules.
For engineers reviewing the ADUM142D0BRWZ datasheet, ADUM142D0BRWZ pinout, ADUM142D0BRWZ application, or ADUM142D0BRWZ equivalent, key selection criteria include its RW-16 wide-body SOIC package (7.8 mm creepage), fail-safe low output configuration, AEC-Q100 qualification, and compatibility with 1.8 V/3.3 V/5 V logic domains on either side of the isolation barrier.
Technical Context
The ADUM142D0BRWZ implements four independent unidirectional isolation channels using monolithic air-core transformers, ensuring dc-correct output states without input transitions. Its architecture supports asymmetric supply operation (e.g., 1.8 V on side 1, 5 V on side 2) and includes integrated undervoltage lockout (UVLO) with 1.5 V/1.6 V thresholds and 0.1 V hysteresis per side.
It features two enable inputs (VE1, VE2) that control channel directionality and tristate behavior, and supports fail-safe low output state during power loss or disable. The device meets DIN EN IEC 60747-17 (VDE 0884-17) for reinforced insulation and achieves 100 kV/µs common-mode transient immunity under full load conditions.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar digital isolation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADUM142E0BRWZ | Pin-compatible; fail-safe high output instead of low; identical RW-16 package and 3.75 kVRMS rating | Required where system logic defaults high during fault (e.g., enable lines for safety relays) | Select ADUM142E0BRWZ only when active-high fail-safe behavior is mandated by safety architecture |
| SI8642ED-B-IS | 4-channel, 3.75 kVRMS, 150 Mbps; capacitive isolation; different pinout (SOIC-16 narrow body); no AEC-Q100 qualification | Suitable for cost-sensitive industrial automation but not automotive or medical systems requiring VDE 0884-17 | Choose SI8642ED-B-IS for non-safety-critical 3.3 V systems where PCB space is constrained and AEC-Q100 is unnecessary |
Compared with ADUM142E0BRWZ, the ADUM142D0BRWZ provides fail-safe low output essential for disabling power stages during faults; compared with SI8642ED-B-IS, it offers automotive qualification and VDE 0884-17 compliance critical for high-reliability applications.

FAQ
What is the isolation voltage rating of the ADUM142D0BRWZ?
The ADUM142D0BRWZ has a rated dielectric insulation voltage of 3.75 kVRMS for 1 minute, verified per UL 1577 and DIN EN IEC 60747-17 (VDE 0884-17). This applies to its RW-16 wide-body SOIC package, which provides 7.8 mm creepage and clearance-meeting reinforced insulation requirements for IEC 61010-1 and IEC 60601-1 systems. The ADUM142D0BRWZ is certified for this rating under standardized test conditions.
Does the ADUM142D0BRWZ support level translation between different supply voltages?
Yes, the ADUM142D0BRWZ supports true bidirectional level translation: VDD1 and VDD2 operate independently across 1.8 V to 5 V. For example, it can accept 1.8 V logic inputs on side 1 while driving 5 V CMOS outputs on side 2. Input thresholds scale with respective VDD (VIH = 0.7×VDDx), and output VOH/VOL specs are referenced to their local VDD. This capability is intrinsic to the ADUM142D0BRWZ design and requires no external components.
What fail-safe behavior does the ADUM142D0BRWZ exhibit during power loss?
The ADUM142D0BRWZ is configured as a fail-safe low device: when VDD1 or VDD2 is unpowered, or when DISABLE1 is asserted, all outputs (OA–OD) transition to and hold a logic low state. This behavior is hard-coded in the ADUM142D0BRWZ silicon and ensures predictable deactivation of downstream drivers or safety circuits-critical in motor control and BMS applications where undefined outputs could cause hazardous conditions.
Is the ADUM142D0BRWZ pin-compatible with other devices in the ADuM142x family?
Yes, the ADUM142D0BRWZ is pin-compatible with ADUM142E0BRWZ and ADUM142D1BRWZ within the same RW-16 package. All share identical pin assignments, electrical characteristics, and package dimensions. The suffix 'D0' denotes fail-safe low output, 'E0' denotes fail-safe high, and 'D1' indicates opposite channel directionality-but mechanical and PCB footprint compatibility is maintained across these variants, including the ADUM142D0BRWZ.
What safety certifications does the ADUM142D0BRWZ hold?
The ADUM142D0BRWZ is certified to UL 1577 (3000 V rms), IEC/EN/CSA 60950-1, IEC/CSA 60601-1, IEC/CSA 61010-1, CQC GB 4943.1, and DIN EN IEC 60747-17 (VDE 0884-17). It also meets AEC-Q100 Grade 1 for automotive use. These certifications are explicitly listed in the official ADUM142D/ADUM142E datasheet Rev. K and apply directly to the ADUM142D0BRWZ part number.
