Product details

Overview

ADUM242E1BRWZ-RL from Analog Devices is a quad-channel 5.0 kV_rms digital isolator using iCoupler® technology, providing reinforced isolation between microcontroller and high-voltage power stage in motor drives. It delivers 150 Mbps data rate, 13 ns max propagation delay at 5 V, and operates across 1.8 V–5 V supply rails with fail-safe high output configuration.

For engineers reviewing the ADUM242E1BRWZ-RL datasheet, ADUM242E1BRWZ-RL pinout, ADUM242E1BRWZ-RL application, or ADUM242E1BRWZ-RL equivalent, this page provides verified electrical specs, SOIC_W package details, safety certifications (UL 1577, VDE 0884-17), and real-world use cases in industrial SPI isolation and IEC 61010-1 compliant equipment.

Technical Context

The ADUM242E1BRWZ-RL implements four independent unidirectional channels with input-side power (VDD1) and output-side power (VDD2) decoupled, enabling level translation between 1.8 V and 5 V logic domains. Its air-core transformer isolation architecture ensures dc-correct output states without input transitions.

It features backward pin compatibility with ADuM2400/ADuM2401/ADuM2402, supports fail-safe high output on power loss, and integrates undervoltage lockout (UVLO) with 1.6 V threshold to prevent metastable operation during brownout conditions.

Pinout & Package

ADUM242E1BRWZ-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 in high-voltage applications.

Pin/Terminal	Circuit Role	Design Meaning
VDD1	Input-side power supply	Supplies logic side (channels A–D inputs); UVLO active below 1.6 V
GND1	Input-side ground reference	Reference for all input signals and VDD1; must be separated from GND2 by isolation barrier
INA, INB, INC, IND	Input data terminals	Unidirectional CMOS-compatible inputs accepting 1.8 V–5 V logic levels
VDD2	Output-side power supply	Supplies isolated side (channels A–D outputs); independent of VDD1
GND2	Output-side ground reference	Reference for all output signals and VDD2; galvanically isolated from GND1
OUTA, OUTB, OUTC, OUTD	Output data terminals	Fail-safe high outputs; drive 4 mA loads at VDD2 − 0.4 V (3.3 V logic)
DISABLE1	Input disable control	Pull-down enabled; disables inputs when driven high, forcing outputs to fail-safe state
VE2	Output enable control	Pull-up enabled; tristates outputs when driven low, preserving isolation integrity

Key Features

Feature	Design Value
iCoupler® transformer isolation	Monolithic air-core transformers replace optocouplers-no LED aging, no CTR degradation, 50+ year lifetime
Backward pin compatibility	Direct drop-in replacement for ADuM2400/ADuM2401/ADuM2402-no PCB redesign required
Level translation	1.8 V logic on VDD1 side interfaces seamlessly with 5 V logic on VDD2 side-enables mixed-voltage system design
DIN EN IEC 60747-17 (VDE 0884-17)	Reinforced insulation certified to 849 V_peak - satisfies medical (IEC 60601-1) and test equipment (IEC 61010-1) safety standards
Low dynamic power	0.01 mA/Mbps input current - reduces thermal load in space-constrained motor control enclosures

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
ADUM242D1BRWZ-RL	Fail-safe output state is low (not high); otherwise identical pinout, speed, and isolation rating	Preferred where default-low output prevents unintended activation of N-channel MOSFETs in high-side configurations	Select ADUM242D1BRWZ-RL only when system-level fail-safe behavior requires low-state default
SI8642ED-B-IS	Capacitive isolation; 5.0 kV_rms, 150 Mbps, but VIORM = 600 V_peak (vs. 849 V_peak) and lacks VDE 0884-17 certification	Suitable for industrial automation but not medical or high-reliability test equipment requiring 2 MOPP	Choose SI8642ED-B-IS only if VDE 0884-17 compliance is not mandated and cost sensitivity outweighs certification needs

Compared with ADUM242D1BRWZ-RL, the ADUM242E1BRWZ-RL provides fail-safe high output critical for preventing shoot-through in half-bridge drivers; versus SI8642ED-B-IS, it delivers higher VIORM and full VDE 0884-17 certification essential for medical and precision test equipment.

FAQ

What is the maximum guaranteed data rate for ADUM242E1BRWZ-RL?

The ADUM242E1BRWZ-RL guarantees a maximum 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 specification is validated per the datasheet's switching characteristics tables and applies to all four channels simultaneously under standard test conditions (CL = 15 pF, CMOS levels). Higher rates may be achievable but are not production-guaranteed.

Does ADUM242E1BRWZ-RL support level translation between different supply voltages?

Yes, ADUM242E1BRWZ-RL 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 allows, for example, interfacing a 1.8 V FPGA I/O bank on the input side with a 3.3 V isolated ADC on the output side-without external level shifters-while maintaining full 150 Mbps throughput and timing integrity.

What safety certifications does ADUM242E1BRWZ-RL hold?

ADUM242E1BRWZ-RL holds UL 1577 (5000 V_rms), DIN EN IEC 60747-17 (VDE 0884-17) for reinforced insulation (849 V_peak), IEC/CSA 62368-1, IEC/CSA 60601-1 (2 MOPP), and IEC/CSA 61010-1. These certifications are verified for the RW-16 SOIC_W package and apply directly to the ADUM242E1BRWZ-RL device as shipped.

How does the fail-safe output behavior work on ADUM242E1BRWZ-RL?

The ADUM242E1BRWZ-RL features a fail-safe high output configuration: when VDD1 is unpowered or the DISABLE1 pin is asserted high, all four outputs (OUTA–OUTD) transition to and remain in a logic high state. This behavior is implemented via internal circuitry-not external pull-ups-and is guaranteed across temperature and voltage extremes, making it ideal for preventing unintended gate turn-on in isolated power stages.

Is ADUM242E1BRWZ-RL pin-compatible with earlier ADuM240x devices?

Yes, ADUM242E1BRWZ-RL is explicitly pin-compatible with ADuM2400/ADuM2401/ADuM2402 per the datasheet's "Backward compatibility" feature statement. The pin functions, spacing, and SOIC_W footprint match exactly-enabling drop-in replacement in existing designs without layout changes, provided the fail-safe high output behavior aligns with system requirements.
