Product details
Overview
MAX14932BAWE+ from Analog Devices is a 4-channel, 2.75kVRMS 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 (CMTI), and operates with independent 1.71V–5.5V supplies on each side-enabling use as a level translator in industrial SPI and RS-485 isolation.
For engineers reviewing the MAX14932BAWE+ datasheet, MAX14932BAWE+ pinout, MAX14932BAWE+ application, or MAX14932BAWE+ equivalent, this page provides verified specifications, functional pin mapping, safety-certified isolation parameters, and design-ready alternatives for high-reliability fieldbus and battery management systems.
Technical Context
The MAX14932BAWE+ implements capacitive galvanic isolation using Analog Devices' proprietary process, with four independent unidirectional channels (A-side inputs → B-side outputs). Its architecture supports default-low output state and features integrated enable controls (ENA/ENB) for channel gating, enabling low-power sleep modes in isolated communication interfaces.
It meets VDE 0884-11 Basic Insulation requirements with 630VPK repetitive peak voltage (VIORM), 443VRMS working voltage (VIOWM), and withstands ±10kV surge per IEC 61000-4-5. The device is production-tested at 120% of 2750VRMS for 1 second and rated for continuous operation from –40°C to +125°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar digital isolator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADUM4402BRWZ | 4-channel, 2.5kVRMS, 100Mbps max, default-high outputs, 16-pin wide SOIC | Lacks 150Mbps capability; lower CMTI (15kV/µs); UL/VDE certified but VIOWM = 375VRMS | Choose when 100Mbps suffices and default-high logic behavior aligns with system reset strategy. |
| SI8642ED-B-IS | 4-channel, 3.75kVRMS, 150Mbps, default-low, 16-pin wide SOIC, higher VIOWM (560VRMS) | Higher isolation rating but no VDE 0884-11 certification; different enable timing (tEN = 12ns vs. 5.1ns typ.) | Prefer where enhanced working voltage margin is critical and VDE certification is not mandated. |
Compared with ADUM4402BRWZ and SI8642ED-B-IS, the MAX14932BAWE+ uniquely combines 150Mbps speed, 25kV/µs CMTI, VDE 0884-11 compliance, and default-low outputs in a single 16-pin wide SOIC package-making it optimal for high-noise, high-speed industrial SPI and fieldbus designs requiring certified basic insulation.

FAQ
What is the maximum data rate supported by the MAX14932BAWE+?
The MAX14932BAWE+ supports a maximum data rate of 150Mbps, verified across all supply voltages (1.71V–5.5V) and temperatures (–40°C to +125°C). This enables high-speed isolated SPI, digital encoder, and sensor interface applications without signal degradation or timing violations.
Does the MAX14932BAWE+ require external pull-up or pull-down resistors on its inputs or outputs?
No, the MAX14932BAWE+ does not require external pull-up or pull-down resistors. Its inputs have defined VIH/VIL thresholds and low leakage (<±1µA), while outputs drive rail-to-rail logic levels (VOH = VDD–0.4V, VOL ≤ 0.4V) capable of sinking/sourcing 4mA directly-eliminating need for external biasing.
What safety certifications does the MAX14932BAWE+ hold?
The MAX14932BAWE+ is certified to UL 1577 (3750VRMS), cUL (CSA 5A), VDE 0884-11 (Basic Insulation), and TUV standards. It meets IEC 61010-1 and IEC 60601-1 requirements with 443VRMS working voltage (VIOWM), 630VPK repetitive peak voltage (VIORM), and ±10kV surge immunity per IEC 61000-4-5.
How does the enable function (ENA/ENB) operate on the MAX14932BAWE+?
The ENA and ENB pins on the MAX14932BAWE+ are active-high enables that place the corresponding OUTA and OUTB outputs into high-impedance (three-state) mode when low. tTRI (enable-to-three-state) is as fast as 2.7ns (typ.), allowing dynamic channel gating in time-critical isolated buses.
Can the MAX14932BAWE+ be used for bidirectional communication like I²C?
No, the MAX14932BAWE+ is strictly unidirectional (A-side inputs → B-side outputs). For bidirectional protocols such as I²C, Analog Devices recommends the MAX14933-its dedicated bidirectional counterpart in the same family-with matching isolation ratings and package options.
