Product details
Overview
ADUM241E1BRWZ-RL from Analog Devices is a quad-channel digital isolator based on iCoupler® technology, providing 5.0 kVrms reinforced insulation for high-noise industrial and medical systems. 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 SPI isolation for isolated ADC/DAC interfaces where signal integrity and safety compliance are critical.
For engineers reviewing the ADUM241E1BRWZ-RL datasheet, ADUM241E1BRWZ-RL pinout, ADUM241E1BRWZ-RL application, or ADUM241E1BRWZ-RL equivalent, this page provides verified specifications, SOIC_W package details, fail-safe output behavior, regulatory approvals (UL 1577, VDE 0884-17, IEC 60601-1), and validated alternative options for multichannel isolation design.
Technical Context
The ADUM241E1BRWZ-RL implements four independent unidirectional channels using monolithic air-core transformers and CMOS interface circuitry, enabling dc-correct operation without input transitions. Its architecture supports asymmetric supply configurations (e.g., 1.8 V on side 1, 3.3 V on side 2) and includes integrated undervoltage lockout (UVLO) with 1.6 V threshold and 0.1 V hysteresis on both sides.
It features two enable inputs (VE1, VE2) controlling channel directionality and output tristate states, with pull-up/pull-down currents specified for logic control. The device meets reinforced insulation requirements per DIN EN IEC 60747-17 (VDE 0884-17) with VIORM = 849 Vpeak, and achieves 100 kV/µs common-mode transient immunity under full-rated voltage stress.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Isolation Rating | 5.0 kVrms for 1 minute - enables reinforced insulation in medical (2 MOPP) and industrial safety-critical applications |
| Max Data Rate | 150 Mbps - supports high-speed SPI, RS-485, and digital encoder interfaces without timing margin loss |
| Propagation Delay | 13 ns max at 5 V - ensures tight timing alignment in real-time control loops and synchronized sampling systems |
| Supply Range | 1.8 V to 5 V per side - allows direct interfacing between low-voltage microcontrollers and higher-voltage peripherals |
| Common-Mode Immunity | 100 kV/µs - maintains signal integrity in motor drives, inverters, and PLC I/O modules exposed to fast transients |
| Fail-Safe Output | High-state default on power loss - prevents undefined logic states in safety-shutdown paths and watchdog circuits |
| Operating Temperature | −40°C to +125°C - qualified for under-hood automotive and industrial ambient environments |
Pinout & Package
ADUM241E1BRWZ-RL uses a 16-lead, RoHS-compliant SOIC_W (RW-16) wide-body 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 logic and isolation circuitry for input-side channels A–D; supports 1.8 V–5 V operation |
| GND1 | Primary-side ground reference | Return path for VDD1; must be isolated from secondary-side ground by ≥7.8 mm PCB spacing |
| VA, VB, VC, VD | Input data channels | Unidirectional logic inputs referenced to VDD1; accept CMOS levels with 0.3×/0.7× VDD1 thresholds |
| VE1, VE2 | Channel enable controls | Active-high enables for directional control; VE1 enables A/B outputs, VE2 enables C/D outputs |
| VDD2 | Secondary-side power supply | Supplies output drivers and receiver circuitry; independent of VDD1, enabling level translation |
| GND2 | Secondary-side ground reference | Return path for VDD2; galvanically isolated from GND1 per reinforced insulation requirements |
| OA, OB, OC, OD | Output data channels | CMOS-compatible outputs referenced to VDD2; fail-safe high when VE1/VE2 inactive or VDD2 absent |
Key Features
| Feature | Design Value |
|---|---|
| iCoupler® transformer isolation | Monolithic air-core transformers eliminate LED aging and temperature drift issues inherent in optocouplers |
| DC-correct operation | Maintains output state during input inactivity - essential for watchdog timeout detection and safe state retention |
| Asymmetric supply support | Enables 1.8 V MCU ↔ 3.3 V/5 V peripheral bridging without external level shifters in isolated SPI buses |
| Reinforced insulation certification | UL 1577, VDE 0884-17, and IEC 60601-1 (2 MOPP) compliance validated for patient-connected medical equipment |
| Low dynamic power | 0.01 mA/Mbps input current - reduces thermal load in densely packed isolated gate driver or sensor interface boards |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad-channel digital isolator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADUM241D1BRWZ-RL | Same SOIC_W package and pinout, but D1 variant has opposite fail-safe state (low instead of high) | Required where system safety logic mandates active-low default on power loss | Select D1 if hardware reset paths require asserted-low enable or latch-up prevention in fault conditions |
| SI8641ED-B-IS | 4-channel, 5 kVrms, 150 Mbps, but uses capacitive isolation and different enable logic (active-low) | Lacks IEC 60601-1 2 MOPP certification; rated for IEC 62368-1 only | Choose for cost-sensitive industrial automation where medical certification is not required |
Compared with ADUM241D1BRWZ-RL, the ADUM241E1BRWZ-RL provides fail-safe high outputs critical for active-high enable chains; versus SI8641ED-B-IS, it delivers certified 2 MOPP isolation needed in diagnostic imaging and patient-connected systems.

FAQ
What is the maximum guaranteed data rate for ADUM241E1BRWZ-RL?
The ADUM241E1BRWZ-RL guarantees a maximum data rate of 150 Mbps across all operating conditions (−40°C to +125°C, 1.8 V to 5 V supplies). This is validated per the datasheet's switching specifications table and applies to all four channels simultaneously with pulse width distortion maintained below 3 ns. Higher rates may function but are not production-tested or warranted.
Does ADUM241E1BRWZ-RL support level translation between different supply voltages?
Yes, ADUM241E1BRWZ-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 direct interfacing between 1.8 V microcontrollers and 3.3 V or 5 V peripherals without external level shifters, as confirmed in the General Description and Electrical Characteristics sections.
What safety certifications does ADUM241E1BRWZ-RL hold?
ADUM241E1BRWZ-RL is certified to UL 1577 (5000 Vrms), DIN EN IEC 60747-17 (VDE 0884-17) for reinforced insulation (849 Vpeak), IEC/CSA 60601-1 (2 MOPP), and IEC/CSA 62368-1. These are explicitly listed in Tables 12 and 13 of the Rev. E datasheet and apply to the RW-16 SOIC_W package variant.
How does the fail-safe output behavior work on ADUM241E1BRWZ-RL?
When either VDD1 or VDD2 is absent or falls below UVLO threshold (1.5 V), or when VE1/VE2 are deasserted, the ADUM241E1BRWZ-RL outputs (OA–OD) transition to and hold a logic high state. This behavior is intrinsic to the E1 variant and is documented in the Features section and Truth Tables of the datasheet as "fail-safe high".
Is ADUM241E1BRWZ-RL pin compatible with earlier ADuM240x series devices?
Yes, ADUM241E1BRWZ-RL is pin compatible with ADuM2400/ADuM2401/ADuM2402 per the datasheet's Features section, which states "ADuM240E1/ADuM241E1/ADuM242E1 pin compatible with ADuM2400/ADuM2401/ADuM2402". This includes identical SOIC_W footprint, pin numbering, and functional mapping for all 16 terminals.
