Product details
Overview
ADUM242E0WBRWZ-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 fail-safe high output configuration. It is used in isolated SPI interfaces for motor drives and PLC I/O modules.
For engineers reviewing the ADUM242E0WBRWZ-RL datasheet, ADUM242E0WBRWZ-RL pinout, ADUM242E0WBRWZ-RL application, or ADUM242E0WBRWZ-RL equivalent, this page provides verified specifications, SOIC_W package layout, safety certifications (UL 1577, VDE 0884-17), and direct alternatives for multichannel isolation design-in.
Technical Context
The ADUM242E0WBRWZ-RL implements four independent unidirectional channels using monolithic air-core transformers, ensuring dc-correct output states without input transitions. Its architecture supports asymmetric voltage translation (e.g., 1.8 V side to 5 V side) and includes integrated undervoltage lockout (UVLO) with 1.6 V threshold on both sides.
It features tight channel matching (≤3.0 ns codirectional skew), low jitter (70 ps rms at 5 V), and robust common-mode transient immunity of 100 kV/µs - validated under ±800 V transients at 1000 V common-mode bias. The device meets reinforced insulation requirements per IEC 60747-17 (VDE 0884-17) and IEC 60601-1 (2 MOPP).
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 (IEC 62368-1) safety-critical systems |
| Data Rate | 150 Mbps maximum guaranteed - supports high-speed SPI, RS-485, and digital encoder interfaces without timing margin loss |
| Propagation Delay | 13 ns max at 5 V - ensures sub-15 ns timing budget for real-time control loops in servo drives |
| Supply Range | 1.8 V to 5 V on both sides - allows level translation between low-voltage microcontrollers and higher-voltage peripherals |
| Common-Mode Immunity | 100 kV/µs - maintains signal integrity in noisy environments like variable-frequency drives and factory automation |
| Fail-Safe Output | High-state default on power loss - prevents undefined logic states in safety-monitored circuits |

Pinout & Package
ADUM242E0WBRWZ-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. Input-side pins (1–8) and output-side pins (9–16) are physically segregated to meet IEC 60601-1 2 MOPP requirements.
| Pin/Terminal | Circuit Role | Design Meaning |

| 5, 6 | VDD1, GND1 | Primary-side power and ground - supplies input-side logic and isolation barrier transmitter |
| 7, 8 | DISABLE1, VE2 | Input-side disable control and enable pull-up - allows tristate input channels during sleep mode |
| 9, 10, 11, 12 | Output Channels A–D | CMOS outputs referenced to VDD2; drive 4 mA loads with rail-to-rail swing |
| 13, 14 | VDD2, GND2 | Secondary-side power and ground - powers receiver circuitry and output buffers |
| 15, 16 | DISABLE2, VE1 | Output-side disable and enable pull-up - enables independent output channel shutdown |
Key Features

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 |
|---|---|---|---|
| ADUM242E1WBRWZ-RL | Pin-compatible but with fail-safe low output state instead of high; identical timing, isolation, and supply specs | Required where system defaults must assert logic-low on power loss (e.g., active-low enable lines) | Select ADUM242E1WBRWZ-RL only when hardware reset logic requires low-state default behavior |
| SI8642ED-B-IS | Capacitive isolation; 5 kVrms, 150 Mbps, but 15 ns max propagation delay and no 1.8 V support on secondary side | Acceptable for non-automotive industrial use where 1.8 V compatibility is not required | Choose SI8642ED-B-IS if cost sensitivity outweighs need for ultra-low propagation delay and dual-supply flexibility |
Compared with ADUM242E0WBRWZ-RL, ADUM242E1WBRWZ-RL offers identical performance with inverted fail-safe polarity, while SI8642ED-B-IS trades 2 ns higher delay and reduced voltage flexibility for lower unit cost in less demanding applications.

FAQ
What is the maximum guaranteed data rate for ADUM242E0WBRWZ-RL?
The ADUM242E0WBRWZ-RL guarantees a maximum data rate of 150 Mbps across all operating conditions (−40°C to +125°C, 1.8 V–5 V supplies). This value is tested and specified in the datasheet Table 1 under "Data Rate" with CL = 15 pF and CMOS signal levels. Higher rates may be achievable but are not production-guaranteed.
Does ADUM242E0WBRWZ-RL support 1.8 V operation on both sides simultaneously?
Yes, ADUM242E0WBRWZ-RL supports 1.8 V operation on both VDD1 and VDD2 sides, as confirmed in Table 7 (Electrical Characteristics-1.8 V Operation). Propagation delay remains ≤15 ns, and common-mode transient immunity stays at 100 kV/µs, enabling low-power isolated interfaces in battery-powered or energy-efficient systems.
What safety certifications apply to ADUM242E0WBRWZ-RL?
ADUM242E0WBRWZ-RL holds 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 documented in Tables 12 and 13 of the Rev. E datasheet and verified for the RW-16 SOIC_W package variant.
How does the fail-safe high output function in ADUM242E0WBRWZ-RL?
The ADUM242E0WBRWZ-RL defaults its outputs to logic high when VDD1 or VDD2 is unpowered or when DISABLE1/DISABLE2 is asserted. This behavior is inherent to the E0 variant and ensures defined states during power sequencing or fault conditions - critical for preventing unintended actuation in safety-rated systems.
Is ADUM242E0WBRWZ-RL pin-compatible with earlier ADuM240x series devices?
Yes, ADUM242E0WBRWZ-RL is pin-compatible with ADuM2400/ADuM2401/ADuM2402 per the datasheet's "Backward compatibility" section. It shares identical SOIC_W footprint, pin assignments, and functional mapping - allowing drop-in replacement where enhanced CMTI or updated safety certification is required.
