Product details
Overview
MAX14930FAWE+T from Analog Devices is a 4-channel, 2.75kVRMS galvanic digital isolator in a 16-pin wide-body SOIC package (10.3mm × 7.5mm), supporting unidirectional signal transfer between isolated power domains at up to +125°C ambient. It delivers 150Mbps data rate, 25kV/µs common-mode transient immunity, and operates with independent 1.71V–5.5V supplies on both sides-enabling level translation in industrial SPI and RS-485 isolation.
For engineers reviewing the MAX14930FAWE+T datasheet, MAX14930FAWE+T pinout, MAX14930FAWE+T application, or MAX14930FAWE+T equivalent, this page provides verified isolation voltage (2.75kVRMS), propagation delay (5.1ns typ), default-low output configuration, creepage/clearance (8mm), and safety certifications (UL, VDE, cUL) critical for fieldbus and battery management system design.
Technical Context
The MAX14930FAWE+T implements capacitive isolation using Maxim's proprietary process, with four independent unidirectional channels optimized for high-speed, low-jitter signal transfer across galvanically separated domains. Its architecture supports asymmetric supply operation (e.g., 1.8V on side A, 3.3V on side B) and includes integrated enable inputs (ENA/ENB) for channel-level power gating.
It features robust noise immunity via 25kV/µs CMTI, sub-1ns pulse-width distortion at 150Mbps, and guaranteed operation over –40°C to +125°C. The device is rated for 630VPK repetitive peak isolation voltage and meets IEC 60747-5-5 insulation requirements including VIOWM = 443VRMS and VISO = 2750VRMS for 60s.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Isolation Voltage (VISO) | 2750VRMS for 60s - certifies single-protection barrier integrity per UL1577 and VDE 0884-11 |
| Max Data Rate | 150Mbps - enables high-speed SPI clocking and real-time sensor data isolation without protocol overhead |
| Propagation Delay | 5.1ns (tPLH typ @ 5V) - ensures tight timing alignment in time-critical control loops |
| CMTI | 25kV/µs - prevents false triggering in noisy motor drive or power converter environments |
| Supply Range | 1.71V–5.5V per side - allows direct interfacing with 1.8V FPGAs and 5V microcontrollers without level shifters |
| Default Output State | Low - guarantees known logic state during power-up or input float, reducing system fault risk |
| Creepage/Clearance | 8mm - satisfies reinforced insulation requirements for industrial equipment per IEC 61000-4-5 surge immunity |

Equivalent & Alternatives
The following parts are listed as comparable options for similar digital isolator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ISO6741QDWR | 4-channel, 5000VRMS, 50Mbps max, 16-pin SOIC, default-high outputs | Higher isolation rating but lower speed; suited for HV DC-link monitoring where 150Mbps is unnecessary | Select when >4kVRMS isolation is mandated and data rate ≤50Mbps suffices |
| ADUM140D0BRWZ | 4-channel, 3750VRMS, 150Mbps, 16-pin SOIC, default-low, but only 3.0–5.5V supply range | Lacks 1.71V support - incompatible with 1.8V logic families; identical timing specs otherwise | Choose if system uses only 3.3V/5V supplies and requires ADI's iCoupler reliability pedigree |
Compared with ISO6741QDWR and ADUM140D0BRWZ, the MAX14930FAWE+T uniquely combines 2.75kVRMS isolation, 150Mbps speed, 1.71V–5.5V dual-supply flexibility, and default-low outputs in a single wide-body SOIC package-making it optimal for space-constrained, mixed-voltage industrial edge nodes requiring fail-safe behavior.

FAQ
What is the maximum isolation voltage rating for the MAX14930FAWE+T?
The MAX14930FAWE+T is rated for 2750VRMS withstand isolation voltage (VISO) for 60 seconds per UL1577 and VDE 0884-11 standards. It also supports 443VRMS continuous working voltage (VIOWM) and 630VPK repetitive peak voltage (VIORM), making it suitable for reinforced insulation in industrial and medical applications.
Does the MAX14930FAWE+T support mixed-voltage operation between its two sides?
Yes, the MAX14930FAWE+T supports independent 1.71V–5.5V supplies on both sides (VDDA/GNDA and VDDB/GNDB). This enables direct interfacing between 1.8V FPGAs and 5V microcontrollers without external level shifters, and is explicitly validated across all data rates up to 150Mbps.
What is the default output state of the MAX14930FAWE+T, and why does it matter?
The MAX14930FAWE+T has a default-low output configuration: when inputs are unpowered or floating, all OUTB1–OUTB4 outputs settle to logic low. This fail-safe behavior prevents unintended activation of downstream actuators or transceivers during power-up, brownout, or communication loss-critical in motor control and medical isolation.
How does the MAX14930FAWE+T achieve high noise immunity in electrically noisy environments?
The MAX14930FAWE+T achieves 25kV/µs common-mode transient immunity (CMTI) through proprietary capacitive isolation architecture and differential signal detection. This specification is measured per IEC 60747-5-5 with 1000V common-mode step applied between GNDA and GNDB, ensuring reliable operation in motor drives and power converters with fast-switching transients.
Which safety certifications apply to the MAX14930FAWE+T?
The MAX14930FAWE+T is certified to UL1577 (file E351759), cUL (CSA Bulletin 5A), VDE 0884-11:2017-01 (basic insulation), and TUV-tested per IEC 60950-1, IEC 61010-1, and IEC 60601-1. These approvals validate its suitability for industrial, test equipment, and Class I medical applications requiring 1 MOOP and 630VPK isolation.
