Product details

Overview

ADUM241D0BRWZ from Analog Devices is a quad-channel digital isolator using 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, enabling robust SPI/data converter isolation in industrial motor drives.

For engineers reviewing the ADUM241D0BRWZ datasheet, ADUM241D0BRWZ pinout, ADUM241D0BRWZ application, or ADUM241D0BRWZ equivalent, key selection criteria include its fail-safe low output state, SOIC_W-16 package with 7.8 mm creepage/clearance, and compatibility with 1.8 V–5 V logic on both sides of the isolation barrier.

Technical Context

The ADUM241D0BRWZ implements four independent unidirectional channels with input-side control (D0 variant), where Channels A/B/C are input-to-output and Channel D is output-enable controlled. Its monolithic air-core transformer architecture ensures dc-correct output states without input transitions and delivers tight channel matching (≤3.0 ns).

It features dual supply domains (VDD1/VDD2), undervoltage lockout (1.5 V/1.6 V thresholds), and high common-mode transient immunity (100 kV/µs). Safety certification includes UL 1577 (5000 V_rms, 1 min), DIN EN IEC 60747-17 (VDE 0884-17), and IEC 60601-1 (2 MOPP) for medical applications.

Key Specifications

Parameter	Value and Actual Design Meaning
Isolation Rating	5.0 kV_rms for 1 minute - meets reinforced insulation requirements per UL 1577 and IEC 60601-1 (2 MOPP)
Data Rate	150 Mbps maximum guaranteed - supports high-speed SPI, RS-485, and digital power control loops
Propagation Delay	13 ns max at 5 V - enables precise timing in real-time control systems with minimal latency
Supply Voltage Range	1.8 V to 5 V on both sides - allows mixed-voltage system interfacing and low-power operation

VDD1	Input-side power supply	Supplies logic power for Channels A/B/C inputs and internal circuitry; range 1.8–5 V
GND1	Input-side ground reference	Reference for all input signals and VDD1; must be isolated from GND2
INA, INB, INC	Digital input signals (Ch A/B/C)	Accept CMOS-level signals; drive isolated outputs OUTA/OUTB/OUTC
INH	Output-enable control input	Active-high enable for Channel D output; low disables OUTD to high-impedance state
VDD2	Output-side power supply	Supplies logic power for all outputs and internal receiver circuitry; range 1.8–5 V
GND2	Output-side ground reference	Reference for all outputs and VDD2; galvanically isolated from GND1
OUTA, OUTB, OUTC	Isolated digital outputs (Ch A/B/C)	CMOS-compatible outputs driven by corresponding inputs; fail-safe low when disabled
OUTD	Isolated output with enable control (Ch D)	Driven only when INH = high; tristates when INH = low - enables shared-bus arbitration

Key Features

Feature	Design Value

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
ADUM241D1BRWZ	Fail-safe high output state instead of low; otherwise identical specs and pinout	Required where default-active logic is needed (e.g., enable lines that must assert on power loss)	Select ADUM241D1BRWZ only when system-level fail-safe behavior mandates high-state default
ISO6741QDWR	TI device with 5000 V_rms rating, 100 Mbps max data rate, and 16-pin SOIC package but different pin assignment and no 1.8 V support	Lower speed and no 1.8 V operation limit use in ultra-low-power or high-throughput designs	Choose ISO6741QDWR only if existing TI ecosystem integration outweighs need for 150 Mbps or 1.8 V compatibility

Compared with ADUM241D1BRWZ, the ADUM241D0BRWZ provides fail-safe low outputs critical for de-energizing safety circuits, while versus ISO6741QDWR it delivers 50% higher data rate and full 1.8 V–5 V flexibility-both essential for next-generation industrial and automotive isolation.

FAQ

What is the fail-safe output state of the ADUM241D0BRWZ?

The ADUM241D0BRWZ has a fail-safe low output state: when the input-side power (VDD1) is absent or the device is disabled, all outputs (OUTA–OUTD) default to logic low. This behavior is confirmed in the datasheet's General Description and Truth Tables sections and ensures safe shutdown in power-loss scenarios for the ADUM241D0BRWZ.

Does the ADUM241D0BRWZ support 1.8 V logic on both sides of the isolation barrier?

Yes, the ADUM241D0BRWZ supports 1.8 V to 5 V operation on both VDD1 and VDD2 supplies, enabling true bidirectional level translation. Electrical Characteristics tables for 1.8 V operation confirm propagation delay (15 ns max), data rate (150 Mbps), and noise immunity (100 kV/µs) remain valid - a key capability of the ADUM241D0BRWZ.

What safety certifications does the ADUM241D0BRWZ hold?

The ADUM241D0BRWZ is certified to UL 1577 (5000 V_rms, 1 min), DIN EN IEC 60747-17 (VDE 0884-17), IEC/CSA 62368-1, IEC/CSA 60601-1 (2 MOPP), and IEC/CSA 61010-1. These approvals are explicitly listed in Tables 12 and 13 of the datasheet and apply to the RW-16 SOIC_W package used by the ADUM241D0BRWZ.

How does the ADUM241D0BRWZ differ from the ADUM241E0BRWZ?

The ADUM241D0BRWZ and ADUM241E0BRWZ share identical electrical specs and package, but differ in pin compatibility: ADUM241E0BRWZ is pin-compatible with legacy ADUM2400-series devices, whereas ADUM241D0BRWZ is not. The "D" suffix denotes a distinct pinout optimized for new designs, as stated in the datasheet's Backward Compatibility section for the ADUM241D0BRWZ.

What is the minimum creepage distance of the ADUM241D0BRWZ package?

For the ADUM241D0BRWZ in the RW-16 SOIC_W package, the minimum external creepage distance is 7.8 mm (Table 9), measured along the package body between input and output terminals. This value satisfies IEC 60601-1 requirements for 2 MOPP in medical applications at pollution degree 2 and altitudes ≤2000 m - a defined specification for the ADUM241D0BRWZ.
