Product details

Overview

ADUM242E1BRWZ from Analog Devices is a quad-channel digital isolator based on iCoupler® technology, providing 5.0 kV_rms 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 up to 125°C, serving as a high-reliability signal isolator in industrial SPI interfaces and motor control gate drivers.

For engineers reviewing the ADUM242E1BRWZ datasheet, ADUM242E1BRWZ pinout, ADUM242E1BRWZ application, or ADUM242E1BRWZ equivalent, this page delivers verified specifications, SOIC_W-16 pin mapping, fail-safe output behavior, safety certifications (UL 1577, VDE 0884-17), and direct alternatives for multichannel isolation design-in.

Technical Context

The ADUM242E1BRWZ implements four independent unidirectional channels using monolithic air-core transformer coupling, with dc-correct output states maintained even during input inactivity. Its architecture ensures tight channel matching (≤3.0 ns codirectional skew) and low jitter (70 ps rms at 5 V), enabling precise timing in synchronized systems like isolated ADC interfaces and servo feedback loops.

It features dual supply domains (VDD1/VDD2), each supporting 1.8–5 V operation, with independent undervoltage lockout (UVLO) thresholds (1.6 V rising) and fail-safe output options-outputs default high when VDD1 is unpowered. The device is qualified for automotive applications and meets IEC 60601-1 (2 MOPP) and IEC 61010-1 (Cat. III/IV) requirements.

Key Specifications

Parameter	Value and Actual Design Meaning
Isolation Rating	5.0 kV_rms for 1 minute - enables reinforced insulation in medical (IEC 60601-1) and industrial (IEC 61010-1) safety-critical systems
Data Rate	150 Mbps maximum guaranteed - supports high-speed SPI, RS-485 transceiver control, and real-time sensor data isolation
Propagation Delay	13 ns max at 5 V - ensures sub-15 ns timing alignment critical for closed-loop motor control and isolated PWM generation
Common-Mode Transient Immunity	100 kV/µs - maintains signal integrity in noisy environments such as variable-frequency drives and power converter gate drive circuits
Supply Voltage Range	1.8 V to 5 V per side - allows mixed-voltage system interfacing (e.g., 1.8 V FPGA to 3.3 V MCU) without external level shifters
Operating Temperature	−40°C to +125°C - supports under-hood automotive and industrial ambient conditions without derating
Fail-Safe Output State	High - outputs default logic high when VDD1 is absent, preventing undefined states in safety-critical enable/disable paths

Pinout & Package

ADUM242E1BRWZ uses a 16-lead RoHS-compliant SOIC_W (wide-body) package (RW-16), with 7.8 mm creepage/clearance and reinforced insulation rated for 5.0 kV_rms. Input-side pins (1–8) and output-side pins (9–16) are physically segregated to maintain isolation integrity.

9, 10, 11, 12 (VDD2)	Output-side power supply	Independent 1.8–5 V domain; powers output buffers and enables level translation
13, 14, 15, 16 (GND2)	Output-side ground reference	Return path for VDD2; galvanically isolated from GND1; defines secondary-side logic reference
A1, B1, C1, D1 (Pins 1–4)	Input data channels	CMOS-compatible inputs; VIH = 0.7×VDD1, VIL = 0.3×VDD1; no external pull-ups required
A2, B2, C2, D2 (Pins 9–12)	Output data channels	CMOS outputs; VOH ≥ VDD2 − 0.4 V @ 4 mA; VOL ≤ 0.4 V @ 4 mA; fail-safe high when VDD1 = 0

Equivalent & Alternatives

The following parts are listed as comparable options for similar quad digital isolator applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
ADUM242D1BRWZ	Same SOIC_W-16 package and pinout, but fail-safe output defaults low instead of high	Preferred where safety logic requires active-low enable or reset assertion on power loss	Select ADUM242D1BRWZ only if system-level fault response mandates low-default outputs
SI8642ED-B-IS	Capacitive isolation; 5 kV_rms; 150 Mbps; 15 ns max delay; different pinout (SOIC-16 narrow)	Requires PCB redesign due to non-pin-compatible layout and different VDD/GND pin assignments	Choose SI8642ED-B-IS only when migrating to Silicon Labs' ecosystem or requiring lower dynamic current at 100 Mbps

Compared with ADUM242D1BRWZ and SI8642ED-B-IS, ADUM242E1BRWZ uniquely combines fail-safe high outputs, iCoupler reliability, and drop-in compatibility with legacy ADuM2400-series layouts-making it optimal for safety-critical upgrades without hardware revision.

FAQ

What is the maximum guaranteed data rate for ADUM242E1BRWZ?

The ADUM242E1BRWZ guarantees a maximum data rate of 150 Mbps across all operating conditions (−40°C to +125°C, 1.8 V to 5 V). This is validated per datasheet Table 1 and applies to all four channels simultaneously with pulse width distortion <3 ns. Higher rates may function but are not production-tested or warranted.

Does ADUM242E1BRWZ support level translation between different supply voltages?

Yes, ADUM242E1BRWZ 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 FPGAs and 3.3 V microcontrollers without external translators-verified in Electrical Characteristics tables for 1.8 V, 2.5 V, 3.3 V, and 5 V operation.

What safety certifications does ADUM242E1BRWZ hold?

ADUM242E1BRWZ is certified to UL 1577 (5000 V_rms, 1 min), DIN EN IEC 60747-17 (VDE 0884-17, 849 V_peak VIORM), IEC/CSA 62368-1, IEC/CSA 60601-1 (2 MOPP), and IEC/CSA 61010-1. Certifications apply specifically to the RW-16 SOIC_W package variant, as documented in Tables 12 and 13 of the Rev. E datasheet.

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

When VDD1 is unpowered or below UVLO threshold (1.5 V), the ADUM242E1BRWZ outputs (A2–D2) transition to and remain in a logic high state-this is inherent to the E1 variant's internal circuitry. This behavior prevents floating or undefined states in gate driver enable lines or safety interlock circuits during primary-side power faults.

Is ADUM242E1BRWZ pin-compatible with earlier ADuM240x series isolators?

Yes, ADUM242E1BRWZ is explicitly pin-compatible with ADuM2400/ADuM2401/ADuM2402 per datasheet Features section. It shares identical SOIC_W-16 footprint, pin numbering, and functional assignment-enabling drop-in replacement in existing designs without PCB modification, provided the fail-safe high output aligns with system requirements.
