Product details
Overview
ADUM5402CRWZ from Analog Devices is a quad-channel digital isolator with integrated isoPower® DC-to-DC converter, delivering regulated 3.3 V or 5.0 V isolated output up to 500 mW, supporting data rates up to 25 Mbps (NRZ), and rated for 2.5 kVrms isolation. It serves as a complete galvanic barrier in RS-485 transceivers and industrial PLC I/O modules.
For engineers reviewing the ADUM5402CRWZ datasheet, ADUM5402CRWZ pinout, ADUM5402CRWZ application, or ADUM5402CRWZ equivalent, key selection criteria include its integrated 3.3/5.0 V isolated supply, 25 Mbps channel speed, 16-lead SOIC package with 7.6 mm creepage, −40°C to +105°C operation, and reinforced insulation per VDE 0884-2.
Technical Context
The ADUM5402CRWZ implements iCoupler® chip-scale transformer technology for both signal isolation and isolated power transfer, eliminating external DC-DC converters. Its isoPower core uses high-frequency PWM (625 kHz) and RF oscillation (180 MHz) to deliver regulated output with load regulation ≤5% and ripple ≤75 mVp-p at full load.
All four channels are unidirectional with inputs on side 1 (VIA, VIB, VIC, VID) and outputs on side 2 (VOA, VOB, VOC, VOD), enabling asymmetric signal routing in fieldbus interfaces. The device features undervoltage lockout (2.4 V/2.7 V thresholds) and common-mode transient immunity >25 kV/μs across the full temperature range.
Key Specifications

Pinout & Package
The ADUM5402CRWZ is housed in a 16-lead SOIC wide-body package (RW-16) with 7.6 mm minimum creepage distance and reinforced insulation barrier between side 1 (pins 1–8) and side 2 (pins 9–16).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| Thermal robustness | Rated for continuous operation at +105°C ambient; junction-to-ambient θJA = 45°C/W on standard 4-layer board |
| Low EMI design | Controlled edge rates (2.5 ns rise/fall) and internal filtering minimize conducted emissions - simplifies EMC validation |
Applications
| RS-485 Transceiver Isolation | Industrial PLC Digital I/O |
|---|---|
Use Scenario: Isolating half-duplex RS-485 communication lines in factory automation networks exposed to ground potential differences and lightning-induced surges.

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 |
|---|---|---|---|
| ADUM5402ARWZ | Same pinout and functionality, but A-grade (1 Mbps max data rate, wider propagation delay range: 55–100 ns) | Suitable for cost-sensitive, lower-speed applications such as basic I/O isolation where 25 Mbps is unnecessary | Select ADUM5402ARWZ only if system timing budget allows ≥55 ns delay and data rate ≤1 Mbps |
| SI88442CC-IS | Quad-channel isolator with integrated 5 V DC-DC (350 mW), 25 Mbps, but uses capacitive isolation and lacks VDE 0884-2 reinforced certification | Applicable where UL/CSA recognition suffices but VDE-level reinforced insulation is not mandated | Choose SI88442CC-IS when prioritizing lower EMI over regulatory scope, or when footprint compatibility with Si88xx family is required |
Compared with ADUM5402ARWZ, the ADUM5402CRWZ enables higher-speed deterministic control; compared with SI88442CC-IS, it provides broader global safety certification (VDE 0884-2) critical for EU industrial equipment, at the cost of slightly higher quiescent current.

FAQ
What is the maximum isolated output power of the ADUM5402CRWZ?
The ADUM5402CRWZ delivers up to 500 mW of regulated isolated power when configured for 5.0 V output from a 5.0 V input supply. At 5 V → 3.3 V configuration, it provides 330 mW; at 3.3 V → 3.3 V, it supplies 200 mW. These values are specified in Table 1 of the ADUM5402CRWZ datasheet and reflect continuous operation under recommended conditions.
Does the ADUM5402CRWZ support bidirectional data channels?
No, the ADUM5402CRWZ has four unidirectional channels with fixed input-side (VIA–VID, pins 1–4, 7–8) and output-side (VOA–VOD, pins 11–14) assignments. This architecture is confirmed in Figures 2 and 3 of the ADUM5402CRWZ datasheet and distinguishes it from bidirectional variants like ADUM5401/ADUM5403. Signal direction cannot be reversed in-circuit.
How is the isolated output voltage selected on the ADUM5402CRWZ?
The ADUM5402CRWZ output voltage is set by the VSEL pin: connect VSEL to GNDISO for 3.3 V output, or tie VSEL to VISO for 5.0 V output. This selection is explicitly defined in the General Description and Table 1 of the ADUM5402CRWZ datasheet and determines both regulation setpoint and maximum load current capability.
What safety certifications does the ADUM5402CRWZ hold?
The ADUM5402CRWZ is certified to UL 1577 (2500 Vrms, 1 min), CSA Component Acceptance Notice 5A, VDE 0884-2 (IEC 60747-5-2) for reinforced insulation (VIORM = 560 Vpeak), and CQC GB4943.1-2011. These approvals are listed in Table 15 and Regulatory Information sections of the ADUM5402CRWZ datasheet.
Can the ADUM5402CRWZ operate with a 3.3 V primary supply and deliver 5.0 V isolated output?
No - the ADUM5402CRWZ cannot generate 5.0 V isolated output from a 3.3 V primary supply. Per Table 1 and Electrical Characteristics sections, valid configurations are: 5.0 V input → 5.0 V or 3.3 V output; or 3.3 V input → 3.3 V output. Attempting 3.3 V → 5.0 V violates the ADUM5402CRWZ's isoPower architecture and is not supported.
