Product details
Overview
ADUM241E1WBRWZ-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 in a wide-body SOIC package.
For engineers reviewing the ADUM241E1WBRWZ-RL datasheet, ADUM241E1WBRWZ-RL pinout, ADUM241E1WBRWZ-RL application, or ADUM241E1WBRWZ-RL equivalent, key selection criteria include common-mode transient immunity (100 kV/µs), fail-safe output state configuration, regulatory compliance (UL, VDE, IEC 60601-1), and backward pin compatibility with ADuM2400/ADuM2401/ADuM2402 series.
Technical Context
The ADUM241E1WBRWZ-RL implements four independent unidirectional channels with input-side power (VDD1) and output-side power (VDD2) operating independently from 1.8 V to 5 V. Its iCoupler® architecture uses monolithic air-core transformers to ensure dc-correct output behavior without input transitions.
It features two fail-safe options (high or low), enable/disable control per side, and meets reinforced insulation requirements per DIN EN IEC 60747-17 (VDE 0884-17) with VIORM = 849 Vpeak and certified 5.0 kVrms withstand voltage for 1 minute.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Isolation Rating | 5.0 kVrms for 1 minute - enables reinforced insulation in medical (IEC 60601-1) and industrial safety-critical systems |
| Data Rate | 150 Mbps maximum guaranteed - supports high-speed SPI, RS-485, and digital power control interfaces |
| Propagation Delay | 13 ns max at 5 V - ensures tight timing alignment in real-time control loops and synchronized sampling |
| Common-Mode Transient Immunity | 100 kV/µs - maintains signal integrity in noisy motor drives and inverters with fast switching transients |
| Supply Voltage Range | 1.8 V to 5 V on both sides - enables level translation between mixed-voltage domains (e.g., 1.8 V MCU ↔ 3.3 V sensor) |
| Operating Temperature | −40°C to +125°C - supports under-hood automotive and industrial ambient conditions |
| Fail-Safe Output | Configurable high or low - prevents undefined states during power loss or input disable in safety-critical subsystems |
Pinout & Package
ADUM241E1WBRWZ-RL is housed in a 16-lead RoHS-compliant wide-body SOIC package (RW-16, 10.3 mm × 10.3 mm), optimized for 5.0 kVrms reinforced insulation with 7.8 mm creepage and clearance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD1 | Input-side supply | Power for channels A–D input circuitry; accepts 1.8–5 V; enables logic-level translation from low-voltage controllers |
| GND1 | Input-side ground | Reference return for VDD1; must be isolated from GND2 by ≥7.8 mm PCB spacing |
| INA, INB, INC, IND | Input signals | Four independent CMOS-compatible inputs referenced to VDD1/GND1; no external pull-ups required |
| VE1 | Input-side enable | Active-high enable for all input-side receivers; disables inputs when low, forcing outputs to fail-safe state |
| VDD2 | Output-side supply | Power for output drivers; independent of VDD1; supports 1.8–5 V for level-shifted outputs |
| GND2 | Output-side ground | Reference return for VDD2; galvanically isolated from GND1; defines output logic thresholds |
| OUTA, OUTB, OUTC, OUTD | Isolated outputs | Four CMOS outputs referenced to VDD2/GND2; maintain dc correctness even with no input activity |
| VE2 | Output-side enable | Active-high enable for all output drivers; tristates outputs when low; internal pull-down |
Key Features
| Feature | Design Value |
|---|---|
| iCoupler® transformer isolation | Monolithic air-core transformers eliminate LED aging and temperature drift issues inherent in optocouplers |
| Backward pin compatibility | Direct replacement for ADuM2400/ADuM2401/ADuM2402 - no PCB redesign needed for upgrade paths |
| High-temperature operation | Rated up to +125°C ambient - suitable for engine control units and industrial PLC modules |
| Low dynamic power | 0.01–0.02 mA/Mbps - reduces thermal load in dense isolation layouts and battery-powered gate drivers |
| Regulatory certifications | UL 1577, VDE 0884-17, IEC 60601-1 (2 MOPP), IEC 62368-1 - accelerates end-equipment safety certification |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad digital isolator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADUM241D1WBRWZ-RL | Same pinout and package; lower propagation delay skew (6.1 ns vs. 7.5 ns) but no fail-safe option | Lacks configurable fail-safe output - unsuitable where defined state on power loss is mandatory | Select when minimal channel skew is prioritized over fail-safe behavior in non-safety-critical control links |
| SI8641ED-B-IS | Different pinout (SOIC-16); 5.0 kVrms, 150 Mbps, but uses capacitive isolation and lacks IEC 60601-1 certification | No 2-MOPP medical approval; higher CMTI (150 kV/µs) but lower VIORM (600 Vpeak) | Consider for cost-sensitive industrial automation where medical certification is not required |
Compared with ADUM241D1WBRWZ-RL and SI8641ED-B-IS, the ADUM241E1WBRWZ-RL uniquely combines pin compatibility with legacy ADuM240x, programmable fail-safe outputs, and full IEC 60601-1 2-MOPP compliance-making it the only choice for upgrading existing medical or automotive designs requiring safety-certified, drop-in replacements.

FAQ
What is the maximum guaranteed data rate for the ADUM241E1WBRWZ-RL?
The ADUM241E1WBRWZ-RL guarantees a maximum 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 is validated per the datasheet's switching specifications 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 the ADUM241E1WBRWZ-RL support level translation between different supply voltages?
Yes, the ADUM241E1WBRWZ-RL supports true 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 interfacing a 1.8 V FPGA I/O bank with a 3.3 V ADC or a 5 V microcontroller with a 2.5 V sensor interface - all while maintaining signal integrity and timing accuracy across the isolation barrier.
What safety certifications does the ADUM241E1WBRWZ-RL hold?
The ADUM241E1WBRWZ-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 reinforced insulation rating of 849 Vpeak (VIORM) and 5.0 kVrms withstand voltage are verified per these standards, making it suitable for Class I medical devices and industrial safety systems.
How does the fail-safe output function work on the ADUM241E1WBRWZ-RL?
The ADUM241E1WBRWZ-RL offers configurable fail-safe outputs that transition to a predetermined logic state (high or low) when VDD1 or VDD2 is absent, or when VE1/VE2 is deasserted. This behavior is implemented via internal circuitry - no external components required - and ensures predictable system behavior during power sequencing faults or brownouts, critical for automotive and industrial control applications.
Is the ADUM241E1WBRWZ-RL pin compatible with earlier ADuM240x series isolators?
Yes, the ADUM241E1WBRWZ-RL is explicitly stated in the datasheet as pin compatible with ADuM2400/ADuM2401/ADuM2402. This includes identical pin assignments for VDD1, GND1, inputs, VDD2, GND2, and outputs - enabling direct replacement in existing PCB layouts without modification, provided the fail-safe configuration matches the design intent.
