Product details
Overview
MAX14932EAWE+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 at up to 150Mbps with 1.71V–5.5V dual-supply operation and default-low output configuration. It enables isolated SPI, RS-485, and industrial I/O interfaces in battery management and medical systems operating from –40°C to +125°C.
For engineers reviewing the MAX14932EAWE+T datasheet, MAX14932EAWE+T pinout, MAX14932EAWE+T application, or MAX14932EAWE+T equivalent, this page delivers verified isolation ratings (2.75kVRMS/60s, 443VRMS continuous), channel timing specs (tPLH/tPHL ≤ 7.5ns at 5V), CMTI ≥ 25kV/µs, and safety certifications (UL1577, VDE 0884-11 Basic Insulation) critical for high-reliability industrial and medical designs.
Technical Context
The MAX14932EAWE+T implements capacitive isolation using Maxim's proprietary process, with four independent unidirectional channels (A-side inputs → B-side outputs), enabling asymmetric data flow for protocols like SPI where clock/data directionality is fixed. Its dual 1.71V–5.5V supplies support level translation between disparate logic domains without external circuitry.
It features integrated enable controls (ENA/ENB) for three-state output management, low propagation delay skew (<1.6ns channel-to-channel same-direction), and robust noise immunity via 25kV/µs common-mode transient immunity. The device is rated for continuous operation at +125°C ambient and qualified per IEC 60747-5-5 for reinforced insulation integrity.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Isolation Rating (VISO) | 2.75kVRMS for 60s - meets reinforced insulation requirements for industrial safety standards including UL1577 and VDE 0884-11. |
| Working Voltage (VIOWM) | 443VRMS continuous - supports long-term operation in mains-connected equipment with basic insulation compliance per IEC 61010-1. |
| Max Data Rate | 150Mbps - enables high-speed isolated communication for real-time control loops and fast serial interfaces. |
| Propagation Delay (tPLH/tPHL) | 5.1–14ns (1.71–5.5V supply range) - ensures tight timing margins in synchronous protocols like isolated SPI clock domains. |
| CMTI | ≥25kV/µs - prevents false triggering during fast transients in motor drives and power converters. |
| Supply Range | 1.71V to 5.5V per side - allows direct interfacing with 1.8V microcontrollers and 5V legacy peripherals without level shifters. |
| Operating Temp | –40°C to +125°C - qualified for under-hood automotive, industrial PLC, and battery pack monitoring environments. |
Pinout & Package
Package: 16-pin wide-body SOIC (W16M+8), 10.3mm × 7.5mm, 8mm creepage/clearance, RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| INA1–INA4 | A-side digital inputs | Accept logic signals referenced to GNDA; compatible with 1.71V–5.5V input thresholds (VIH = 0.7×VDDA). |
| OUTB1–OUTB4 | B-side digital outputs | Drive loads referenced to GNDB; VOH = VDDB – 0.4V, VOL = 0.4V at 4mA sink/source. |
| VDDA / VDDB | Independent power supplies | Enable galvanic isolation and level translation; each side operates autonomously across full 1.71V–5.5V range. |
| GNDA / GNDB | Isolated ground references | Define separate return paths; no electrical connection between sides - essential for breaking ground loops. |
| ENA / ENB | Output enable controls | Assert low to place respective side's outputs in high-impedance state; supports dynamic power gating and bus sharing. |
Key Features
| Feature | Design Value |
|---|---|
| 150Mbps high-speed isolation | Enables real-time isolated data acquisition and control in servo drives and high-resolution ADC interfaces. |
| 25kV/µs CMTI | Prevents data corruption in noisy EMI environments such as variable-frequency drives and industrial inverters. |
| 1.71V–5.5V dual-supply flexibility | Eliminates need for external level translators when interfacing 1.8V FPGAs with 3.3V or 5V isolated peripherals. |
| Default-low output state | Ensures safe, known logic state on B-side outputs during power-up or A-side undervoltage lockout (VUVLO = 1.58V typ). |
| VDE 0884-11 Basic Insulation | Validates barrier reliability for medical (IEC 60601-1) and test equipment (IEC 61010-1) applications requiring MOOP-rated isolation. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar digital isolator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SI8641ED-B-IS | 4-channel, 5kVRMS isolation, 150Mbps, 16-pin SOIC (narrow), default-high output | Higher isolation rating suits mains-connected equipment; narrower SOIC saves board space but reduces creepage (4mm vs. 8mm) | Select when >2.75kVRMS isolation or PCB area constraints dominate; verify default-state compatibility with system power sequencing. |

FAQ
What is the maximum data rate supported by the MAX14932EAWE+T?
The MAX14932EAWE+T supports a maximum data rate of 150Mbps, validated across its full 1.71V–5.5V supply range and –40°C to +125°C operating temperature. This performance is specified in the Dynamic Electrical Characteristics table for the MAX1493_B/E variant, which corresponds to the MAX14932 part number. At 5V supply, propagation delay is as low as 5.1ns (tPLH), enabling reliable high-speed SPI and digital I/O isolation.
Does the MAX14932EAWE+T provide reinforced or basic insulation?
The MAX14932EAWE+T is certified for Basic Insulation per DIN VDE V 0884-11:2017-01 and UL1577, with a maximum repetitive peak isolation voltage (VIORM) of 630VPK and working voltage (VIOWM) of 443VRMS. It meets IEC 61010-1 and IEC 60601-1 requirements for 1 MOOP, but is not rated for reinforced insulation. Its 2.75kVRMS withstand rating applies to single-protection applications only.
What is the default output state of the MAX14932EAWE+T?
The MAX14932EAWE+T has a default-low output configuration: when the A-side input is unpowered or undervolted (below VUVLO ≈ 1.58V), all B-side outputs (OUTB1–OUTB4) drive low. This behavior is confirmed in the General Description section and distinguishes it from the MAX14930 (default-high) and MAX14931 (default-low, 25Mbps variant). The suffix "E" in the part number denotes the default-low option.
Can the MAX14932EAWE+T be used for bidirectional protocols like I²C?
No - the MAX14932EAWE+T provides only unidirectional channels (A-side inputs to B-side outputs). It cannot support true bidirectional protocols such as I²C, which require active pull-up and signal arbitration on shared lines. For I²C isolation, Analog Devices specifies the MAX14933, a dedicated bidirectional isolator. Using MAX14932EAWE+T for I²C would require external circuitry and compromise signal integrity and timing.
What safety certifications does the MAX14932EAWE+T hold?
The MAX14932EAWE+T is certified to UL1577 (file E351759), CSA C22.2 No. 5A (cUL), VDE 0884-11 (Basic Insulation), and TÜV-tested per IEC 60950-1, IEC 61010-1, and IEC 60601-1. It achieves 2.75kVRMS isolation for 60 seconds, 443VRMS continuous working voltage, and 10kV surge immunity per IEC 61000-4-5, making it suitable for industrial and Class I medical applications.
