Product details
Overview
ADUM242E1BRIZ-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. It serves as a robust replacement for optocouplers in SPI isolation and fieldbus interfaces.
For engineers reviewing the ADUM242E1BRIZ-RL datasheet, ADUM242E1BRIZ-RL pinout, ADUM242E1BRIZ-RL application, or ADUM242E1BRIZ-RL equivalent, this page provides verified specifications, SOIC_W package details, fail-safe output behavior, safety certifications (UL 1577, VDE 0884-17), and real-world use cases in motor control and isolated ADC interfaces.
Technical Context
The ADUM242E1BRIZ-RL implements four independent unidirectional channels using monolithic air-core transformers, ensuring dc-correct output even without input transitions. Its architecture supports asymmetric supply configurations (e.g., 1.8 V on side 1, 5 V on side 2) and includes integrated undervoltage lockout (UVLO) with 1.6 V turn-on threshold.
It features two fail-safe output states - high or low - selectable via part number suffix; ADUM242E1BRIZ-RL defaults to fail-safe high. Channel matching is ≤3.0 ns codirectional, and common-mode transient immunity reaches 100 kV/µs under 800 V transients, meeting IEC 61000-4-4 Level 4 requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Isolation Rating | 5.0 kVrms for 1 minute - enables reinforced insulation per IEC 60601-1 (2 MOPP) and IEC 61010-1 (Cat III). |
| Data Rate | 150 Mbps guaranteed - supports high-speed SPI, RS-485, and CAN FD isolation without timing margin loss. |
| Propagation Delay | 13 ns max at 5 V - ensures tight timing alignment in real-time control loops and synchronized sampling. |
| Supply Range | 1.8 V to 5 V on both sides - allows direct interfacing between legacy 5 V logic and modern ultra-low-voltage MCUs. |
| Common-Mode Immunity | 100 kV/µs - maintains signal integrity during fast-switching events in motor drives and power converters. |
| Fail-Safe Output | High-state default on power loss - prevents undefined logic states in safety-critical enable/disable paths. |
| Operating Temperature | −40°C to +125°C - qualified for under-hood automotive and industrial ambient environments. |
Pinout & Package
ADUM242E1BRIZ-RL uses a 16-lead, RoHS-compliant wide-body SOIC_W (RW-16) 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 supply | Power for input-side logic and channel 1–2 transmitters; supports 1.8–5 V operation. |
| GND1 | Primary-side ground | Reference for VDD1 and input signals; must be isolated from secondary ground plane. |
| INA, INB | Input channels A/B | CMOS-compatible inputs accepting 0.3×VDD1 / 0.7×VDD1 thresholds; no external pull-ups required. |
| VDD2 | Secondary-side supply | Power for output-side logic and channel 1–2 receivers; independently configurable voltage rail. |
| GND2 | Secondary-side ground | Reference for VDD2 and outputs; galvanically separated from GND1 by 5 kVrms barrier. |
| OUTA, OUTB | Output channels A/B | CMOS outputs with VDD2-referenced VOH/VOL; fail-safe high when VDD2 is unpowered. |
| NC | No-connect pins | Pins 3, 4, 11, 12 are internally unused; must remain unconnected per datasheet layout guidance. |

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 |
|---|---|---|---|
| ADUM242D1BRIZ-RL | Fail-safe output state is low instead of high; identical timing, isolation, and power specs. | Required where system safety logic mandates default-low enable or reset on power loss. | Select when hardware-level fail-safe behavior must assert active-low signals during brownout. |
| SI8642ED-B-IS | Capacitive isolation; 5 kVrms, 150 Mbps, but 15 ns max propagation delay and 10 kV/µs lower CMTI. | Suitable for non-safety-critical consumer or test equipment where cost is prioritized over extreme noise immunity. | Choose only if CMTI >75 kV/µs is not required and UL/VDE certification scope permits capacitive-based solutions. |

FAQ
What is the maximum guaranteed data rate for ADUM242E1BRIZ-RL?
The ADUM242E1BRIZ-RL guarantees a data rate of 150 Mbps across its full operating temperature range (−40°C to +125°C) and supply voltage range (1.8 V to 5 V). This value is tested with CL = 15 pF and CMOS signal levels, and represents the highest rate at which all timing parameters-including pulse width distortion and jitter-remain within specification limits per the Rev. E datasheet.
Does ADUM242E1BRIZ-RL support level translation between different supply voltages?
Yes, ADUM242E1BRIZ-RL supports true bidirectional level translation: VDD1 and VDD2 can operate independently from 1.8 V to 5 V. For example, it can translate 1.8 V logic from an MCU to 5 V logic on an isolated ADC side, with input thresholds scaling to 0.3×VDDx and 0.7×VDDx, and output VOH/VOL referenced to their respective supply rails.
What safety certifications does ADUM242E1BRIZ-RL hold?
ADUM242E1BRIZ-RL is certified to UL 1577 (5000 Vrms, 1 min), DIN EN IEC 60747-17 (VDE 0884-17) for reinforced insulation (849 Vpeak), IEC/CSA 62368-1, IEC/CSA 60601-1 (2 MOPP), and IEC/CSA 61010-1. These approvals are validated for the RW-16 SOIC_W package and documented in Tables 12 and 13 of the Rev. E datasheet.
How does the fail-safe output behavior work on ADUM242E1BRIZ-RL?
ADUM242E1BRIZ-RL is an "E1" variant, meaning its outputs default to logic high when VDD2 is unpowered or the input side is disabled. This behavior is implemented via internal circuitry that overrides output drivers during undervoltage conditions, ensuring predictable high-state signaling in safety-critical enable paths without external pull-up components.
Is ADUM242E1BRIZ-RL pin-compatible with earlier ADuM240x series isolators?
Yes, ADUM242E1BRIZ-RL is pin-compatible with ADuM2400/ADuM2401/ADuM2402 per the datasheet's backward compatibility statement. It shares identical SOIC_W footprint, pin numbering, and functional assignment-enabling drop-in replacement in existing designs while delivering improved CMTI (100 kV/µs vs. 25 kV/µs) and lower propagation delay.
