Product details
Overview
ADUM240D0BRWZ-RL from Analog Devices is a quad-channel digital isolator based on iCoupler® technology, providing 5.0 kVrms reinforced isolation for high-noise industrial and medical systems. It delivers 150 Mbps 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 ADUM240D0BRWZ-RL datasheet, ADUM240D0BRWZ-RL pinout, ADUM240D0BRWZ-RL application, or ADUM240D0BRWZ-RL equivalent, this page provides verified specifications, SOIC_W package details, safety certifications (UL 1577, VDE 0884-17), and real-world design context for high-CMTI signal isolation.
Technical Context
The ADUM240D0BRWZ-RL implements four independent unidirectional channels using monolithic air-core transformer coupling, ensuring dc-correct output states without input transitions. Its architecture supports asymmetric voltage translation-e.g., 1.8 V logic on side 1 and 5 V logic on side 2-enabling interoperability between low-power microcontrollers and higher-voltage peripherals.
It features integrated undervoltage lockout (UVLO) with 1.6 V turn-on threshold and 0.1 V hysteresis per side, plus robust common-mode transient immunity of 100 kV/µs. The device meets reinforced insulation requirements per DIN EN IEC 60747-17 (VDE 0884-17) with VIORM = 849 Vpeak and certified for IEC 60601-1 (2 MOPP) and IEC 61010-1 (Cat. III).

Pinout & Package
RW-16 wide-body SOIC (SOIC_W) package, RoHS compliant, 16-pin surface-mount with 7.8 mm minimum creepage and clearance. Input-side pins (1–8) and output-side pins (9–16) are galvanically isolated.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD1 | Input-side supply | Power for channels A–D inputs; accepts 1.8 V–5 V; UVLO active below 1.5 V |
| GND1 | Input-side ground | Reference for input logic and side-1 circuitry; must be separated from GND2 by isolation barrier |

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 |
|---|---|---|---|
| ADUM240D1BRWZ-RL | Fail-safe output state is low (vs. high in ADUM240D0BRWZ-RL); identical timing, isolation, and packaging | Required where system safety logic mandates default-low assertion on fault (e.g., emergency stop enable lines) | Select ADUM240D1BRWZ-RL only when hardware-level fail-safe behavior must assert low instead of high |
| SI8640ED-B-IS | Capacitive isolation; 5 kVrms, 150 Mbps, but lower CMTI (75 kV/µs) and no 1.8 V support on both sides | Suitable for cost-sensitive industrial controls where 100 kV/µs CMTI is not required and 3.3 V/5 V operation suffices | Choose SI8640ED-B-IS for non-safety-critical applications needing lower BOM cost and smaller footprint (SOIC-16 narrow) |
Compared with ADUM240D1BRWZ-RL, the ADUM240D0BRWZ-RL provides fail-safe high output essential for active-high enable paths; versus SI8640ED-B-IS, it offers superior noise immunity and broader voltage flexibility-making it preferred for medical and high-reliability motor control designs.

FAQ
What is the maximum guaranteed data rate for ADUM240D0BRWZ-RL?
The ADUM240D0BRWZ-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 is validated per datasheet Table 1–Table 7 under specified load (CL = 15 pF) and CMOS signal levels. Higher rates may function but are not production-guaranteed.
Does ADUM240D0BRWZ-RL support level translation between different supply voltages?
Yes, ADUM240D0BRWZ-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 enables direct interfacing between 1.8 V microcontrollers and 5 V peripherals without external level shifters.
What safety certifications apply to ADUM240D0BRWZ-RL?
ADUM240D0BRWZ-RL holds UL 1577 (5 kVrms), DIN EN IEC 60747-17 (VDE 0884-17, 849 Vpeak), IEC/CSA 62368-1, IEC/CSA 60601-1 (2 MOPP), and IEC/CSA 61010-1 certifications. These are verified for the RW-16 SOIC_W package per Tables 9, 12, and regulatory documentation on analog.com.
How does the fail-safe output behavior work in ADUM240D0BRWZ-RL?
In ADUM240D0BRWZ-RL, the outputs default to logic high when either VDD1 or VDD2 is absent or falls below UVLO threshold (1.5 V). This is a hardware-defined state-not software-configurable-and ensures predictable behavior during power sequencing or supply faults in safety-critical paths.
What is the creepage and clearance distance for ADUM240D0BRWZ-RL?
ADUM240D0BRWZ-RL uses the RW-16 wide-body SOIC package with minimum external creepage and clearance of 7.8 mm (per Table 9), meeting IEC 62368-1 and IEC 60601-1 requirements for pollution degree 2 and altitudes ≤2000 m. PCB layout must maintain ≥8.1 mm line-of-sight clearance in the mounting plane.
