Product details
Overview
ADUM240D1BRIZ-RL from Analog Devices is a quad-channel digital isolator using iCoupler® transformer-based isolation, delivering 5.0 kVrms withstand voltage, 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 16-lead SOIC_W package.
For engineers reviewing the ADUM240D1BRIZ-RL datasheet, ADUM240D1BRIZ-RL pinout, ADUM240D1BRIZ-RL application, or ADUM240D1BRIZ-RL equivalent, this page provides verified technical context, safety-certified insulation specs, fail-safe output configuration, and real-world use cases in SPI isolation and industrial field bus systems.
Technical Context
The ADUM240D1BRIZ-RL implements four independent unidirectional CMOS-isolated channels using monolithic air-core transformers, ensuring dc-correct output states without input transitions. Its architecture enables tight channel matching (≤3.0 ns) and low pulse width distortion (≤3 ns), critical for timing-sensitive serial interfaces.
It features dual supply domains (VDD1/VDD2), undervoltage lockout (1.5 V/1.6 V thresholds), and two fail-safe output options-configured via part number suffix. The device meets reinforced insulation requirements per DIN EN IEC 60747-17 (VDE 0884-17) with VIORM = 849 Vpeak and certified to UL 1577, IEC/CSA 62368.1, IEC/CSA 60601-1, and IEC/CSA 61010-1.
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 systems |
| Data Rate | 150 Mbps 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 alignment for synchronous multi-channel communication |
| Common-Mode Transient Immunity | 100 kV/µs - maintains signal integrity in noisy motor drives and power converter environments |
| Supply Voltage Range | 1.8 V to 5 V per side - allows direct interfacing between mixed-voltage domains (e.g., 1.8 V FPGA to 3.3 V MCU) |
| Fail-Safe Output | High-state default on power loss - prevents undefined logic states in safety-monitored control loops |
| Operating Temperature | −40°C to +125°C - supports under-hood automotive and industrial ambient conditions |
Pinout & Package
ADUM240D1BRIZ-RL uses a 16-lead wide-body SOIC_W (RW-16) package with creepage/clearance ≥7.8 mm, rated for 5.0 kVrms isolation. Input-side pins (1–8) and output-side pins (9–16) are physically segregated to maintain reinforced insulation integrity.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD1, GND1 | Primary-side power supply | Supplies isolated input-side logic; supports 1.8–5 V operation with UVLO protection |
| VDD2, GND2 | Secondary-side power supply | Supplies isolated output-side logic; independent voltage domain enables level translation |
| INA, INB, INC, IND | Input data channels | CMOS-compatible inputs accepting 1.8–5 V logic; no external pull-ups required |
| OUTA, OUTB, OUTC, OUTD | Output data channels | Fail-safe high outputs when VDD1 is unpowered; drive 4 mA loads at VDD2 − 0.4 V |
| DISABLE1 | Input disable control | Pull-down enabled; forces inputs to logic low when asserted, reducing dynamic current |
| VE2 | Output enable control | Pull-up enabled; tristates all outputs when low, enabling bus sharing |
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 |
|---|---|---|---|
| ADUM240D0BRIZ-RL | Fail-safe output defaults to low state instead of high; identical pinout, timing, and isolation specs | Preferred where system safety requires active-low reset assertion on power loss | Select based on required default output polarity during VDD1 brownout or disable |
| SI8641ED-B-IS | Capacitive isolation; 5 kVrms, 150 Mbps, but higher PWD (5 ns) and lower CMTI (75 kV/µs) | Lower EMI emissions in RF-sensitive environments; not certified to IEC/CSA 60601-1 | Choose for cost-sensitive industrial controls where medical certification is unnecessary |
Compared with ADUM240D0BRIZ-RL, the ADUM240D1BRIZ-RL provides fail-safe high output behavior essential for enabling circuits, while SI8641ED-B-IS offers capacitive isolation with trade-offs in timing precision and regulatory coverage.

FAQ
What is the maximum guaranteed data rate for ADUM240D1BRIZ-RL?
The ADUM240D1BRIZ-RL guarantees a data rate of 150 Mbps across all operating voltages (1.8 V to 5 V) and temperature ranges (−40°C to +125°C). This value is validated per the datasheet's switching specifications table and applies under standard test conditions (CL = 15 pF, CMOS levels). Higher rates may be achievable but are not production-guaranteed. The ADUM240D1BRIZ-RL achieves this while maintaining pulse width distortion ≤3 ns and jitter ≤70 ps rms at 1.8 V.
Does ADUM240D1BRIZ-RL support level translation between different supply voltages?
Yes, ADUM240D1BRIZ-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 interfacing a 1.8 V FPGA I/O bank with a 3.3 V microcontroller or a 5 V sensor interface without external level shifters. Input thresholds scale with VDDx (VIH = 0.7 × VDDx), and outputs swing rail-to-rail relative to their respective VDD.
What safety certifications apply specifically to ADUM240D1BRIZ-RL?
ADUM240D1BRIZ-RL carries UL 1577 (5000 Vrms, 1 min), DIN EN IEC 60747-17 (VDE 0884-17) with VIORM = 849 Vpeak, IEC/CSA 62368.1, IEC/CSA 60601-1 (2 MOPP), and IEC/CSA 61010-1. These are confirmed for the RW-16 SOIC_W package variant in Tables 9, 12, and 13 of the Rev. E datasheet. The "*" marking on the device denotes VDE 0884-17 compliance.
How does the fail-safe output behavior work on ADUM240D1BRIZ-RL?
ADUM240D1BRIZ-RL is configured as a D1 variant, meaning its outputs default to logic high when VDD1 is unpowered or DISABLE1 is asserted. This behavior is implemented internally via bias circuitry and requires no external components. It ensures defined states in safety-critical paths-for example, keeping a gate driver enabled until primary power is confirmed stable. The D0 variant defaults low; both share identical timing and isolation specs.
Can ADUM240D1BRIZ-RL be used in automotive applications?
Yes, ADUM240D1BRIZ-RL is explicitly qualified for automotive applications per the datasheet's Automotive Products section (page 27) and meets AEC-Q100 Grade 1 (−40°C to +125°C) requirements. It is deployed in battery management systems, onboard chargers, and traction inverter control units where reinforced insulation, high CMTI, and extended temperature operation are mandatory.
