Product details
Overview
MAX14932DAWE+ from Analog Devices is a 4-channel, unidirectional digital isolator with 2.75kVRMS galvanic isolation, 150Mbps maximum data rate, and independent 1.71V–5.5V dual-supply operation across isolated domains. It features default-low output configuration, 6.67ns minimum pulse width, and operates from –40°C to +125°C - enabling robust signal isolation in industrial fieldbus, isolated SPI, and battery management systems.
For engineers reviewing the MAX14932DAWE+ datasheet, MAX14932DAWE+ pinout, MAX14932DAWE+ application, or MAX14932DAWE+ equivalent, this page delivers verified electrical specs (CMTI = 25kV/µs, tPLH/tPHL ≤ 8.2ns at 1.8V), package mapping (16-pin wide SOIC, 10.3mm × 7.5mm), safety certifications (UL1577, VDE 0884-11 Basic Insulation), and real-world design context for high-speed, high-reliability isolation.
Technical Context
The MAX14932DAWE+ implements capacitive isolation with proprietary process technology, supporting only unidirectional channel flow (A→B) across all four channels. Its architecture enables precise timing control via enable inputs (ENA/ENB), low-jitter propagation (peak eye jitter ≤ 160ps at 1.8V), and immunity to fast common-mode transients (25kV/µs).
It supports three supply voltage combinations per side (1.71V–5.5V), allowing level translation between logic families. The device is rated for continuous 443VRMS working voltage (VIOWM) and withstands 10kV surge per IEC 61000-4-5, making it suitable for reinforced insulation in safety-critical industrial and medical applications.

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, 100Mbps, 2.5kVRMS, default-high outputs, 16-pin wide SOIC | Lacks 150Mbps capability and default-low state; lower CMTI (15kV/µs) | Choose when lower speed suffices and default-high logic aligns with system reset behavior |
| SI8642ED-B-IS | 4-channel, 150Mbps, 5kVRMS, default-low, 16-pin wide SOIC, higher VIOWM (667VRMS) | Higher isolation rating but no VDE 0884-11 certification; different enable timing (tEN = 12ns vs. 5.1ns) | Prefer for higher working voltage requirements where VDE certification is not mandated |
Compared with ADUM4402BRWZ and SI8642ED-B-IS, the MAX14932DAWE+ uniquely combines 150Mbps speed, default-low outputs, VDE 0884-11 certification, and 25kV/µs CMTI in a single wide-SOIC package - making it optimal for time-critical, safety-certified industrial and medical designs requiring guaranteed fail-safe states.

FAQ
What is the maximum data rate supported by the MAX14932DAWE+?
The MAX14932DAWE+ supports a maximum data rate of 150Mbps, verified across all supply voltages (1.71V–5.5V) and temperatures (–40°C to +125°C). This performance is achieved with minimal pulse-width distortion (<1ns) and enables high-throughput isolated SPI, RS-485, and digital I/O in real-time control systems. The 150Mbps rating is specified in the MAX1493_B/E dynamic characteristics table of the official datasheet.
Does the MAX14932DAWE+ support bidirectional communication?
No, the MAX14932DAWE+ is strictly unidirectional - all four channels transmit only from side A (INA1–INA4) to side B (OUTB1–OUTB4). For bidirectional applications such as I²C, Analog Devices specifies the MAX14933 as the dedicated alternative. This unidirectional architecture enables optimized timing (e.g., 5.1ns tEN) and lower propagation skew compared to bidirectional isolators.
What safety certifications does the MAX14932DAWE+ hold?
The MAX14932DAWE+ is certified to UL1577 (3750VRMS), CSA C22.2 No. 5A (cUL), and VDE 0884-11:2017-01 for Basic Insulation. 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 - all validated for the 16-pin wide SOIC package.
What is the default output state of the MAX14932DAWE+?
The MAX14932DAWE+ has a default-low output configuration: when any input (INA1–INA4) is unpowered or floating, the corresponding OUTB1–OUTB4 outputs drive low. This fail-safe behavior is confirmed in the General Description section and Ordering Information of the datasheet, and distinguishes it from default-high variants like MAX14932AAWE+.
Can the MAX14932DAWE+ operate with mismatched supply voltages on each side?
Yes - the MAX14932DAWE+ supports independent 1.71V–5.5V supplies on VDDA/GNDA and VDDB/GNDB, enabling seamless level translation. For example, it can interface a 1.8V FPGA (side A) with a 5V RS-485 transceiver (side B) without external level shifters, while maintaining full 150Mbps data rate and 25kV/µs CMTI performance.
