Product details
Overview
ADUM140E1BRWZ from Analog Devices is a quad-channel digital isolator based on iCoupler® technology, providing 3.75 kVRMS reinforced isolation in a wide-body SOIC-16 package. It delivers 150 Mbps guaranteed data rate, 13 ns max propagation delay at 5 V, and operates across 1.8 V to 5 V supply rails with level translation capability. It is used in industrial SPI isolation, motor drive control interfaces, and medical equipment signal barrier applications.
For engineers reviewing the ADUM140E1BRWZ datasheet, ADUM140E1BRWZ pinout, ADUM140E1BRWZ application, or ADUM140E1BRWZ equivalent, this page provides verified specifications, fail-safe output behavior, regulatory compliance (UL, VDE, IEC 60601-1), and real-world design context for high-noise industrial and safety-critical systems.
Technical Context
The ADUM140E1BRWZ implements four independent unidirectional isolation channels using monolithic air-core transformers, enabling dc-correct operation without input transitions. Its architecture ensures tight channel matching (≤3.0 ns codirectional skew) and low jitter (70 ps rms at 5 V), critical for synchronous serial protocols like SPI and isolated ADC interfaces.
It features dual supply domains (VDD1/VDD2), undervoltage lockout (1.5 V–1.6 V thresholds), and two fail-safe output states (high or low) selectable via configuration pins. The device supports AEC-Q100 qualification and meets DIN EN IEC 60747-17 (VDE 0884-17) for reinforced insulation integrity.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Isolation Rating | 3.75 kVRMS for 1 minute - enables reinforced insulation per IEC 60601-1 and IEC 62368-1 in medical and industrial power-supply interfaces |
| Data Rate | 150 Mbps guaranteed - supports high-speed SPI clocking up to 75 MHz with margin for timing closure |
| Propagation Delay | 13 ns max at 5 V - ensures sub-ns timing alignment across all four channels for synchronized sampling |
| Common-Mode Transient Immunity | 100 kV/µs - maintains signal integrity in noisy motor drive and inverter gate-drive environments |
| Supply Voltage Range | 1.8 V to 5 V per side - enables direct interfacing between legacy 3.3 V logic and modern 1.8 V microcontrollers |
| Fail-Safe Output | Configurable high/low state during input power loss - prevents undefined logic states in safety-critical control loops |
| Operating Temperature | −40°C to +125°C - supports under-hood automotive and industrial ambient conditions without derating |
Pinout & Package
ADUM140E1BRWZ is housed in a RoHS-compliant 16-lead wide-body SOIC (RW-16) package with 7.8 mm creepage and clearance, optimized for reinforced insulation in high-voltage systems.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD1 | Primary-side power supply | Supplies input-side logic and isolation transmitter; accepts 1.8 V–5 V |
| GND1 | Primary-side ground reference | Return path for VDD1 domain; must be separated from GND2 by ≥7.8 mm PCB clearance |
| INA, INB, INC, IND | Input signal terminals | CMOS-compatible inputs accepting logic levels referenced to VDD1 |
| VDD2 | Secondary-side power supply | Supplies output-side logic and isolation receiver; independent voltage domain from VDD1 |
| GND2 | Secondary-side ground reference | Return path for VDD2 domain; galvanically isolated from GND1 |
| OUTA, OUTB, OUTC, OUTD | Output signal terminals | CMOS outputs referenced to VDD2; support 4 mA drive strength at 0.4 V VOL |
| DISABLE1 | Input disable control | Pull-down enabled; forces inputs to logic low when asserted, reducing dynamic current |
| VE2 | Output enable control | Pull-up enabled; places outputs in high-impedance state when driven low |
Key Features
| Feature | Design Value |
|---|---|
| iCoupler® transformer isolation | Monolithic air-core CMOS transformers eliminate LED aging and enable >50-year lifetime with no performance drift |
| Level translation | Independent 1.8 V–5 V supplies on each side allow seamless interface between mixed-voltage subsystems |
| Fail-safe output configuration | Outputs default to pre-determined high or low state during VDD1 loss - eliminates floating nodes in fault conditions |
| AEC-Q100 qualification | Qualified to Grade 1 (−40°C to +125°C) for automotive powertrain and battery management systems |
| DIN EN IEC 60747-17 compliance | Meets VDE 0884-17 reinforced insulation requirements including partial discharge and lifetime validation |

Use Scenario: Digital I/O isolation in modular PLC backplanes handling 24 V DC field signals. IC Role / Device Role / Timing Role: Channelized isolation of discrete input status and output command signals across multiple slots. Use Value: 125°C operation supports convection-cooled enclosures; configurable fail-safe outputs prevent actuator misfire during brownout. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar quad digital isolator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADUM140D1BRWZ | Same RW-16 package and 3.75 kVRMS rating, but fixed fail-safe low output (vs. ADUM140E1BRWZ's configurable high/low) | Preferred where deterministic low-state default is required during power loss (e.g., emergency stop circuits) | Select ADUM140D1BRWZ only if fixed low-fail-safe behavior aligns with system safety architecture |
| SI8641ED-B-IS | 4-channel isolator with 5 kVRMS rating, 150 Mbps, but uses capacitive coupling and lacks AEC-Q100 qualification | Suitable for industrial automation but not certified for medical or automotive use per IEC 60601-1 or AEC-Q100 | Choose SI8641ED-B-IS only when higher isolation voltage is prioritized over medical/automotive compliance |
Compared with ADUM140D1BRWZ and SI8641ED-B-IS, ADUM140E1BRWZ uniquely combines AEC-Q100 Grade 1 qualification, configurable fail-safe outputs, and full IEC 60601-1 compliance-making it the only option qualified for safety-critical medical and automotive subsystems requiring flexible fault-state behavior.

FAQ
What is the maximum guaranteed data rate for ADUM140E1BRWZ?
The ADUM140E1BRWZ guarantees a data rate of 150 Mbps across its full operating temperature range (−40°C to +125°C) and supply voltage range (1.8 V to 5 V). This rating is validated per the datasheet's switching specifications and applies to all four channels simultaneously under CL = 15 pF load conditions. Higher rates may be achievable but are not production-guaranteed.
Does ADUM140E1BRWZ support level translation between different supply voltages?
Yes, ADUM140E1BRWZ supports true bidirectional level translation: VDD1 and VDD2 can operate independently from 1.8 V to 5 V. For example, it can translate 1.8 V logic on the input side (VDD1) to 3.3 V logic on the output side (VDD2), enabling interoperability between ultra-low-power sensors and standard microcontrollers without external level shifters.
What safety certifications does ADUM140E1BRWZ hold?
ADUM140E1BRWZ is certified to UL 1577 (3000 V rms for 1 minute), DIN EN IEC 60747-17 (VDE 0884-17) for reinforced insulation, IEC/EN/CSA 60950-1, IEC/CSA 60601-1 (medical), and IEC/CSA 61010-1. It also carries CQC GB 4943.1 and is AEC-Q100 qualified for automotive applications.
How does the fail-safe output configuration work on ADUM140E1BRWZ?
ADUM140E1BRWZ offers user-selectable fail-safe output states (high or low) via the DISABLE1 and VE2 pins. When VDD1 is absent or DISABLE1 is asserted, outputs transition to the pre-configured state-ensuring defined logic levels during power faults. This behavior is implemented in hardware and requires no firmware intervention, making it suitable for SIL-2 and ASIL-B systems.
Is ADUM140E1BRWZ pin-compatible with earlier ADuM1400-series isolators?
Yes, ADUM140E1BRWZ is pin-compatible with ADuM1400, ADuM1401, and ADuM1402 in the same RW-16 package. This backward compatibility allows drop-in replacement in existing designs while adding enhanced features including improved CMTI (100 kV/µs), lower propagation delay, and AEC-Q100 qualification-without requiring PCB layout changes.
