Product details
Overview
ADUM242D1BRIZ from Analog Devices is a quad-channel digital isolator based on 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 operates reliably up to +125°C in industrial and automotive systems requiring high-noise immunity.
For engineers reviewing the ADUM242D1BRIZ datasheet, ADUM242D1BRIZ pinout, ADUM242D1BRIZ application, or ADUM242D1BRIZ equivalent, key selection criteria include its SOIC_W (RW-16) package with 7.8 mm creepage/clearance, fail-safe high output option, and compatibility with SPI, RS-485 transceivers, and isolated power supply feedback loops.
Technical Context
The ADUM242D1BRIZ implements four independent unidirectional channels using monolithic air-core transformers and CMOS interface circuitry, enabling dc-correct signal transmission without input transitions. Its architecture ensures tight channel matching (≤3.0 ns codirectional skew) and low jitter (70 ps rms at 5 V).
It features dual supply domains (VDD1/VDD2), undervoltage lockout (1.5 V/1.6 V thresholds), and robust common-mode transient immunity of 100 kV/µs - validated under 1000 V common-mode voltage with 800 V transient magnitude per IEC 60747-17.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Isolation Rating | 5.0 kVrms for 1 minute - meets reinforced insulation requirements for medical (IEC 60601-1), industrial (IEC 62368-1), and test equipment (IEC 61010-1) safety standards. |
| Data Rate | 150 Mbps maximum guaranteed - supports high-speed SPI, digital encoder, and isolated ADC/DAC interfaces without timing margin loss. |
| Propagation Delay | 13 ns max at 5 V - enables sub-20 ns round-trip latency in closed-loop control systems such as motor drives and UPS feedback paths. |
| Common-Mode Immunity | 100 kV/µs - maintains signal integrity in noisy environments like variable-frequency drives and industrial PLC backplanes. |
| Supply Voltage Range | 1.8 V to 5 V per side - allows direct interfacing with low-voltage microcontrollers (e.g., ARM Cortex-M0+) and legacy 3.3 V/5 V logic without level shifters. |
| Operating Temperature | −40°C to +125°C - qualified for under-hood automotive and industrial ambient conditions per AEC-Q100 stress testing guidelines. |
| Fail-Safe Output | High-state default on input power loss - ensures predictable state in safety-critical monitoring circuits (e.g., overvoltage detection enable lines). |
Pinout & Package
ADUM242D1BRIZ 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 applications.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD1 | Primary-side power supply | Supplies input-side logic and transformer driver; accepts 1.8–5 V with UVLO at 1.5 V/1.6 V. |
| GND1 | Primary-side ground reference | Return path for VDD1 domain; must be isolated from GND2 by ≥7.8 mm PCB spacing. |
| INA, INB, INC, IND | Input data channels A–D | CMOS-compatible inputs with 0.3×VDD1/0.7×VDD1 thresholds; support 150 Mbps toggling. |
| VDD2 | Secondary-side power supply | Supplies output-side logic and receiver; independent voltage domain enables level translation. |
| GND2 | Secondary-side ground reference | Return path for VDD2 domain; galvanically isolated from GND1 per reinforced insulation requirements. |
| OUTA, OUTB, OUTC, OUTD | Output data channels A–D | CMOS outputs with rail-to-rail swing (VOL ≤ 0.1 V, VOH ≥ VDD2 − 0.1 V); fail-safe high when disabled. |
Key Features
| Feature | Design Value |
|---|---|
| iCoupler® transformer isolation | Monolithic air-core transformers eliminate LED aging and temperature drift issues inherent in optocouplers. |
| DC-correct transmission | Maintains output logic state indefinitely without input toggling - critical for watchdog timeout and status latch applications. |
| Low dynamic power | 0.01 mA/Mbps input current enables <10 mA total supply draw at 100 Mbps, reducing thermal load in dense layouts. |
| Automotive qualification | AEC-Q100 Grade 1 (−40°C to +125°C) compliance supports use in engine control units and battery management systems. |

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 |
|---|---|---|---|
| ADUM242E1BRIZ | Pin-compatible but with fail-safe low output state instead of high; identical timing, isolation, and supply specs. | Suitable where default-low assertion is required (e.g., active-low reset lines), whereas ADUM242D1BRIZ asserts high on disable. | Select ADUM242E1BRIZ only when system logic requires low-state default; otherwise ADUM242D1BRIZ provides direct replacement for fail-safe high designs. |
| SI8641ED-B-IS | 4-channel, 5 kVrms, 150 Mbps isolator with 12 ns max propagation delay; uses capacitive isolation and different pinout (SOIC-16 NB). | Requires PCB layout revision due to non-pin-compatible pin assignment and narrower SOIC narrow-body package (5.3 mm width vs. 10.3 mm for RW-16). | Choose SI8641ED-B-IS only if board space constraints prohibit SOIC_W; verify creepage compliance (5.3 mm vs. 7.8 mm) for medical/industrial safety requirements. |
Compared with ADUM242E1BRIZ and SI8641ED-B-IS, ADUM242D1BRIZ uniquely combines fail-safe high output, SOIC_W package with 7.8 mm creepage, and iCoupler® reliability for high-noise industrial and automotive applications where predictable default state and regulatory alignment are mandatory.

FAQ
What is the maximum guaranteed data rate for ADUM242D1BRIZ?
The ADUM242D1BRIZ guarantees a maximum data rate of 150 Mbps across all operating voltages (1.8 V to 5 V) and temperatures (−40°C to +125°C), verified under CL = 15 pF loading and CMOS signal levels per the datasheet's switching specifications table.
Does ADUM242D1BRIZ support level translation between different supply voltages?
Yes, ADUM242D1BRIZ supports 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 seamless interfacing between 1.8 V microcontrollers and 3.3 V or 5 V peripherals without external level shifters.
What safety certifications does ADUM242D1BRIZ hold?
ADUM242D1BRIZ is certified to 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 - all validated for the RW-16 SOIC_W package with 7.8 mm creepage and clearance.
How does the fail-safe output behavior work on ADUM242D1BRIZ?
When VDD1 is unpowered or the input is disabled, ADUM242D1BRIZ drives all outputs high by default. This behavior is intrinsic to the D1 variant and ensures safe, known states in fault conditions - for example, holding an enable line active during power-up sequencing or preventing unintended shutdown.
Is ADUM242D1BRIZ pin-compatible with earlier ADuM240x/ADuM241x series devices?
No - ADUM242D1BRIZ belongs to the ADuM242x family and is not pin-compatible with ADuM2400/ADuM2401/ADuM2402. However, ADUM242D1BRIZ shares pinout with other ADuM242x variants (e.g., ADUM242E1BRIZ) and differs from ADuM240x/ADuM241x in channel configuration and enable logic mapping.
