Product details
Overview
ADUM240E0WBRWZ-RL from Analog Devices is a quad-channel digital isolator using iCoupler® technology, providing 5.0 kVrms reinforced insulation, 150 Mbps guaranteed data rate, and 13 ns max propagation delay at 5 V operation. It supports 1.8 V to 5 V level translation across the isolation barrier and is qualified for automotive applications.
For engineers reviewing the ADUM240E0WBRWZ-RL datasheet, ADUM240E0WBRWZ-RL pinout, ADUM240E0WBRWZ-RL application, or ADUM240E0WBRWZ-RL equivalent, this page delivers verified specifications, fail-safe output behavior, SOIC_W package details, safety certifications (UL 1577, VDE 0884-17), and real-world use cases in SPI isolation and industrial field buses.
Technical Context
The ADUM240E0WBRWZ-RL implements four independent unidirectional channels with fixed input-to-output directionality (A/B/C/D inputs on side 1, outputs on side 2). It uses monolithic air-core transformers for signal coupling, ensuring dc-correct output states without input transitions.
It features two fail-safe options: outputs default high when side 1 power is absent or inputs are disabled. The device includes undervoltage lockout (UVLO) at 1.5 V/1.6 V thresholds and achieves 100 kV/µs common-mode transient immunity under 800 V transients.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Isolation Rating | 5.0 kVrms for 1 minute - meets reinforced insulation requirements per UL 1577 and IEC 60747-17 |
| Data Rate | 150 Mbps maximum guaranteed - supports high-speed SPI, RS-485, and CAN FD interfaces |
| Propagation Delay | 13 ns max at 5 V - enables tight timing budgets in real-time control loops |
| Supply Range | 1.8 V to 5 V on both sides - allows mixed-voltage system interfacing and low-power operation |
| Common-Mode Immunity | 100 kV/µs - maintains signal integrity in noisy motor drives and industrial PLCs |
| Operating Temperature | −40°C to +125°C - qualified for under-hood automotive and industrial environments |
| Fail-Safe Output | Outputs default high when side 1 is unpowered - prevents undefined logic states in safety-critical systems |
Pinout & Package
ADUM240E0WBRWZ-RL is housed in a 16-lead RoHS-compliant SOIC_W (wide-body) package with 7.8 mm creepage and clearance, optimized for reinforced insulation in high-voltage applications.

Equivalent & Alternatives
The following parts are listed as comparable options for similar digital isolator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADUM240D0WBRWZ-RL | Same SOIC_W package and 5.0 kVrms rating, but D-series has different fail-safe behavior (outputs default low) | Required where system logic assumes active-low reset or fault signaling on loss of primary power | Select ADUM240D0WBRWZ-RL only if low-fail-safe behavior matches control architecture |
| SI8640ED-B-IS | 4-channel, 5 kVrms, 150 Mbps, but uses capacitive isolation and lacks VDE 0884-17 certification | Suitable for cost-sensitive industrial controls but not for medical or high-reliability automotive use requiring partial discharge validation | Choose SI8640ED-B-IS for non-safety-critical applications where capacitive isolation suffices and BOM cost is prioritized |
Compared with ADUM240E0WBRWZ-RL, ADUM240D0WBRWZ-RL provides identical performance except inverted fail-safe polarity, while SI8640ED-B-IS trades VDE-certified reliability for lower unit cost and different isolation physics-making each suitable for distinct safety and regulatory tiers.

FAQ
What is the maximum guaranteed data rate for ADUM240E0WBRWZ-RL?
The ADUM240E0WBRWZ-RL guarantees a maximum data rate of 150 Mbps across its full operating temperature and voltage range. This specification is validated per the datasheet's Electrical Characteristics tables and applies to all four channels simultaneously under standard test conditions (CL = 15 pF, CMOS levels). Higher rates may be achievable but are not production-guaranteed.
Does ADUM240E0WBRWZ-RL support level translation between different supply voltages?
Yes, ADUM240E0WBRWZ-RL supports bidirectional level translation: VDD1 can operate from 1.8 V to 5 V independently of VDD2, which also ranges from 1.8 V to 5 V. This allows direct interfacing between, for example, a 1.8 V FPGA I/O bank and a 3.3 V ADC SPI interface without external level-shifting components.
What fail-safe behavior does ADUM240E0WBRWZ-RL exhibit when VDD1 is removed?
When VDD1 is unpowered or inputs are disabled via the DISABLE1 pin, ADUM240E0WBRWZ-RL outputs transition to a predefined high state. This E0-series fail-high behavior prevents floating or undefined logic levels in downstream circuits, enhancing system safety during power sequencing or fault conditions.
Which safety certifications apply to ADUM240E0WBRWZ-RL?
ADUM240E0WBRWZ-RL holds UL 1577 (5000 Vrms), DIN EN IEC 60747-17 (VDE 0884-17), IEC/CSA 62368-1, IEC/CSA 60601-1 (2-MOPP), and IEC/CSA 61010-1 certifications. Its 849 Vpeak VIORM rating and 7.8 mm creepage meet reinforced insulation requirements for medical and industrial equipment.
Is ADUM240E0WBRWZ-RL pin-compatible with earlier ADuM2400-series isolators?
No-ADUM240E0WBRWZ-RL is part of the ADuM240E family and is pin-compatible only with ADuM240E1/ADuM241E1/ADuM242E1 variants, not with legacy ADuM2400/ADuM2401/ADuM2402. The RWZ suffix denotes the SOIC_W package with enhanced creepage, and the E0 designation specifies fail-high output behavior, distinguishing it from D0/D1 variants.
