Product details
Overview
MAX14932FAWE+T from Analog Devices is a 4-channel, 2.75kVRMS galvanic digital isolator in a 16-pin wide 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 MAX14932FAWE+T datasheet, MAX14932FAWE+T pinout, MAX14932FAWE+T application, or MAX14932FAWE+T equivalent, this page delivers verified isolation voltage (2.75kVRMS), CMTI (25kV/µs), propagation delay (5.1ns typ), supply range (1.71–5.5V per side), and safety certifications (UL, VDE, cUL) critical for high-reliability industrial and medical designs.
Technical Context
The MAX14932FAWE+T implements capacitive isolation with differential signaling across a reinforced dielectric barrier, supporting asymmetric 1.71V–5.5V supplies on each side for level translation. Its architecture delivers 150Mbps data rate with <1ns pulse-width distortion and 0.9ns channel-to-channel skew at 5V supplies.
It features integrated enable inputs (ENA/ENB) for three-state control, robust ±4kV HBM ESD protection, and operates across –40°C to +125°C ambient with guaranteed performance at full temperature range. Safety compliance includes UL1577 (3750VRMS), VDE 0884-11 Basic Insulation (4600VPK transient), and IEC 61000-4-5 ±10kV 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 |
|---|---|---|---|
| ADUM4402BRIZ | 4-channel, 5kVRMS, 1Mbps max rate, 20ns propagation delay, 5V-only supply | Lower speed, higher isolation; suited for low-bandwidth safety-critical monitoring, not high-speed comms | Select when >5kVRMS isolation is mandatory and data rate ≤1Mbps suffices |
| SI8642ED-B-IS | 4-channel, 5kVRMS, 150Mbps, 10ns propagation delay, 2.5–5.5V supply, default-high outputs | Same speed and supply flexibility, but lacks default-low state and has lower CMTI (15kV/µs) | Select when default-high logic is acceptable and CMTI >20kV/µs is not required |
Compared with ADUM4402BRIZ and SI8642ED-B-IS, the MAX14932FAWE+T uniquely combines 150Mbps speed, 2.75kVRMS isolation, default-low outputs, and 25kV/µs CMTI in a single wide-SOIC package-making it optimal for high-noise, high-speed industrial and medical isolation where fail-safe startup behavior is essential.

FAQ
What is the maximum data rate supported by the MAX14932FAWE+T?
The MAX14932FAWE+T supports a maximum data rate of 150Mbps under typical conditions (VDDA/VDDB = 5.0V, CL = 15pF). This is confirmed in the Dynamic Electrical Characteristics table for MAX1493_B/E variants, which includes the MAX14932. At lower supply voltages (e.g., 1.8V), the achievable rate remains 150Mbps but with increased propagation delay and jitter.
Does the MAX14932FAWE+T have a default-low or default-high output configuration?
The MAX14932FAWE+T has a default-low output configuration. When its inputs are unpowered or floating, all outputs (OUTA1–OUTA4 and OUTB1–OUTB4) settle to logic low. This behavior is explicitly defined in the General Description section and distinguishes it from the MAX14930 (default-high) and MAX14931 (default-low with different channel mapping).
What safety certifications does the MAX14932FAWE+T hold?
The MAX14932FAWE+T is certified to UL1577 (file E351759, rated 3750VRMS), cUL (CSA Bulletin 5A), VDE 0884-11:2017-01 (Basic Insulation, 4600VPK transient), and TUV for IEC 60950-1, IEC 61010-1, and IEC 60601-1. These certifications cover working voltage (443VRMS), repetitive peak (630VPK), and surge (±10kV) requirements.
Can the MAX14932FAWE+T be used for bidirectional communication like I²C?
No-the MAX14932FAWE+T is a unidirectional isolator only. It supports three fixed channel-direction configurations (all-A-to-B, all-B-to-A, or split), but lacks built-in bidirectional logic required for I²C. For I²C isolation, Analog Devices specifies the MAX14933, which is explicitly designed for open-drain bidirectional channels.
What is the common-mode transient immunity (CMTI) rating of the MAX14932FAWE+T?
The MAX14932FAWE+T has a guaranteed minimum CMTI of 25kV/µs, tested per IEC 60747-5-5 with a 1000V common-mode step applied between GNDA and GNDB. This value is consistent across all members of the MAX14930–MAX14932 family and is validated over the full –40°C to +125°C temperature range.
