Product details
Overview
ADUM5404ARWZ-RL from Analog Devices is a quad-channel digital isolator with integrated isoPower® dc-to-dc converter, delivering up to 500 mW isolated output power at 5.0 V or 3.3 V, supporting 25 Mbps NRZ data rates, and providing 2.5 kV rms isolation in a 16-lead SOIC package with 7.6 mm creepage-used in industrial PLCs and RS-485 transceiver isolation.
For engineers reviewing the ADUM5404ARWZ-RL datasheet, ADUM5404ARWZ-RL pinout, ADUM5404ARWZ-RL application, or ADUM5404ARWZ-RL equivalent, key selection criteria include isolated supply capability (500 mW), channel configuration (4-channel, A-side input / B-side output), common-mode transient immunity (>25 kV/μs), and regulatory compliance (UL, VDE, CQC).
Technical Context
The ADUM5404ARWZ-RL implements iCoupler® chip-scale transformer technology for both signal isolation and isolated power transfer, eliminating external dc-dc converters. Its internal PWM-controlled oscillator (625 kHz) and rectifier regulate VISO to 3.3 V or 5.0 V depending on VSEL configuration.
It features four unidirectional channels with inputs on Side A (pins 1–4, 16) and outputs on Side B (pins 9–12), enabling asymmetric signal flow. Propagation delay skew is ≤15 ns (codirectional), and undervoltage lockout ensures operation only when VDD1, VISO ≥2.4 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Data Rate | 25 Mbps NRZ - supports high-speed serial interfaces like RS-485 without external clock recovery |
| Isolation Voltage | 2500 V rms for 1 min - meets UL 1577, enabling safe separation of hazardous and non-hazardous circuits |
| Output Power | 500 mW at 5 V - powers downstream isolated logic (e.g., microcontroller I/O, transceiver bias) without secondary supply |
| Common-Mode Immunity | >25 kV/μs - maintains signal integrity in noisy industrial environments with fast ground shifts |
| Propagation Delay Skew | ≤15 ns codirectional - ensures tight timing alignment across isolated control signals (e.g., PWM pairs) |
| Operating Temperature | −40°C to +105°C - qualified for extended industrial ambient conditions without derating |
| Creepage Distance | 7.6 mm - satisfies reinforced insulation requirements per IEC 60747-5-2 for 560 V peak working voltage |
Pinout & Package
ADUM5404ARWZ-RL uses a 16-lead wide-body SOIC package (SOIC_W) with 7.6 mm creepage and 8.0 mm air gap, rated for 2500 V rms isolation. Pin 1 marked, body width 10.3 mm, lead pitch 1.27 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3, 4, 16 | Side A Input / VDD1 / GND1 | Primary-side logic inputs (VIA–VID) and power pins - connect to controller-side 3.3 V or 5 V domain |
| 9, 10, 11, 12 | Side B Output / VISO / GNDISO | Isolated-side outputs (VOA–VOD) and regulated isolated supply - powers downstream circuitry directly |
| 5, 6, 7, 8 | Internal Oscillator / Rectifier / Feedback | No user connection - internal isoPower switching nodes; require strict PCB layout per AN-0971 |
| 13, 14, 15 | VSEL, RCOUT, GNDISO | VSEL selects output voltage (GNDISO = 3.3 V, VISO = 5.0 V); RCOUT sets oscillator frequency; all tied to isolated ground |
Key Features
| Feature | Design Value |
|---|---|
| Integrated isoPower® DC-DC | Eliminates need for external isolated supply - reduces BOM count and board area in space-constrained designs |
| Quad unidirectional channels | Fixed A→B directionality (VIA→VOA, VIB→VOB, etc.) - simplifies routing for master-slave communication links |
| High CMTI & low PWD | 25 kV/μs immunity and ≤6 ns pulse width distortion - preserves signal fidelity in motor drive gate driver feedback paths |
| VDE 0884-2 certified | VIORM = 560 V peak - enables use in reinforced insulation systems up to 420 V rms working voltage (tropical climate) |
| Thermal derating support | Safe operating current defined up to 150°C case temperature - allows reliable operation under sustained load in sealed enclosures |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad-channel isolated power applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADUM5404CRWZ-RL | Same pinout and function, but C-grade (−40°C to +105°C) with tighter propagation delay specs (45 ns max vs. 60 ns) | Required for high-speed timing-critical systems (e.g., servo position loops) needing sub-50 ns delay consistency | Select ADUM5404CRWZ-RL when guaranteed 25 Mbps performance at full temperature range is mandatory |
| SI8641ED-IS | 4-channel isolator only - no integrated DC-DC; requires external isolated supply; higher data rate (150 Mbps) | Suitable where isolated power is already available and ultra-high-speed signaling dominates design priority | Choose SI8641ED-IS if board has existing isolated 3.3 V rail and needs faster data throughput than ADUM5404ARWZ-RL supports |
Compared with ADUM5404CRWZ-RL, the ADUM5404ARWZ-RL offers identical functionality at lower cost but with relaxed timing specs; versus SI8641ED-IS, it trades raw speed for self-contained power delivery-making it optimal for compact, low-component-count isolated subsystems.

FAQ
What is the maximum isolated output power of the ADUM5404ARWZ-RL?
The ADUM5404ARWZ-RL delivers up to 500 mW of regulated isolated output power at 5.0 V when supplied with 5.0 V on the primary side. At 3.3 V input, it provides 200 mW at 3.3 V output or 330 mW at 3.3 V output when powered from 5.0 V input-enabling direct powering of isolated transceivers or microcontrollers without external converters.
Does the ADUM5404ARWZ-RL support bidirectional communication?
No, the ADUM5404ARWZ-RL implements four unidirectional channels with fixed A-side inputs (VIA–VID) and B-side outputs (VOA–VOD). It does not support reverse-direction signaling. For bidirectional isolation, designers must pair it with complementary devices or select alternate models like ADUM5401/ADUM5402 with mixed directionality.
How is the output voltage (3.3 V or 5.0 V) selected on the ADUM5404ARWZ-RL?
The ADUM5404ARWZ-RL output voltage is set by the VSEL pin (Pin 13): tying VSEL to GNDISO configures 3.3 V output; connecting VSEL to VISO selects 5.0 V output. This selection is static and must be made at power-up-no dynamic reconfiguration is supported during operation.
What safety certifications apply to the ADUM5404ARWZ-RL?
The ADUM5404ARWZ-RL holds UL recognition (2500 V rms per UL 1577), CSA Component Acceptance Notice 5A, VDE certification to IEC 60747-5-2 (VIORM = 560 V peak), and CQC certification per GB4943.1-2011-validating its suitability for reinforced insulation in industrial and medical applications.
Can the ADUM5404ARWZ-RL operate with a 3.3 V primary supply?
Yes, the ADUM5404ARWZ-RL supports 3.3 V primary operation (VDD1 = 3.0 V to 3.6 V), delivering 3.3 V isolated output at up to 60 mA (200 mW). In this mode, VSEL must be tied to GNDISO. Input current is 14 mA (quiescent) and 175 mA (full load), with efficiency ~33% at maximum output.
