Product details
Overview
MAX14932AAWE+T from Analog Devices is a 4-channel, unidirectional digital isolator with 2.75kVRMS galvanic isolation, 150Mbps 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 - deployed in industrial fieldbus interfaces and isolated SPI buses where high-speed signal integrity and reinforced insulation are critical.
For engineers reviewing the MAX14932AAWE+T datasheet, MAX14932AAWE+T pinout, MAX14932AAWE+T application, or MAX14932AAWE+T equivalent, this page delivers verified electrical specs (including CMTI ≥25kV/µs, tPLH/tPHL ≤7.5ns at 5V), package dimensions (16-pin wide SOIC, 10.3mm × 7.5mm), safety certifications (UL1577, VDE 0884-11 Basic Insulation), and real-world design context for multichannel isolation in harsh environments.
Technical Context
The MAX14932AAWE+T implements capacitive isolation with proprietary silicon-dioxide dielectric barriers, supporting asymmetric voltage operation (e.g., 1.8V on side A, 3.3V on side B) and enabling level translation without external circuitry. Its channel architecture is fully unidirectional (A→B only), eliminating bidirectional contention and simplifying timing analysis in master-slave SPI or RS-485 transceiver control paths.
It integrates enable-controlled three-state outputs (tEN = 5.1ns, tTRI = 2.7ns at 5V), low-glitch rejection (15ns), and ultra-low propagation delay skew (<1.6ns channel-to-channel same-direction). The device meets IEC 61000-4-5 ±10kV surge immunity and sustains 443VRMS working voltage continuously per VDE 0884-11.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Isolation Rating | 2.75kVRMS withstand (60s), 443VRMS continuous working voltage - enables use in Class I medical and industrial mains-connected systems. |
| Data Rate | 150Mbps maximum - supports high-speed SPI clocking up to 75MHz with margin, suitable for real-time sensor data acquisition. |
| Propagation Delay | tPLH/tPHL ≤7.5ns (typ) at 5V - ensures sub-10ns timing budgets for deterministic control loops in motor drives. |
| CMTI | ≥25kV/µs - rejects fast common-mode transients from IGBT switching noise in inverters and power converters. |
| Supply Range | 1.71V–5.5V per side - allows direct interfacing with 1.8V FPGAs and 5V microcontrollers without level shifters. |

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, 150Mbps, 5kVRMS isolation, 2.5V–5.5V supplies, default-high outputs | Higher isolation rating (5kVRMS) but wider 16-pin SOIC (10.3mm × 10.3mm); lacks 1.8V compatibility | Select when higher isolation voltage is required and board space allows larger footprint; verify default-output logic matches system reset behavior. |
| ADUM140D0BRZ | 4-channel, 150Mbps, 3.75kVRMS, 1.7V–5.5V, default-low, 16-pin narrow SOIC (9.9mm × 3.9mm) | Same default-low config and voltage range, but lower isolation (3.75kVRMS) and narrower package - less creepage (4mm vs 8mm) | Choose for space-constrained designs where 3.75kVRMS suffices and 4mm creepage meets end-equipment safety standards. |
Compared with SI8641ED-B-IS and ADUM140D0BRZ, the MAX14932AAWE+T uniquely combines 2.75kVRMS isolation with 8mm creepage in a wide SOIC, 1.8V compatibility, and guaranteed 150Mbps performance across full temperature range - making it optimal for high-density industrial and medical systems requiring both robustness and low-voltage interoperability.

FAQ
What is the maximum data rate supported by the MAX14932AAWE+T?
The MAX14932AAWE+T supports a maximum data rate of 150Mbps, validated across its full operating temperature range (–40°C to +125°C) and supply voltage range (1.71V to 5.5V per side). This performance is specified with 6.67ns minimum pulse width and ≤7.5ns typical propagation delay at 5V, making it suitable for high-speed SPI and digital control applications where timing precision is critical. The 150Mbps rating is not derated at elevated temperatures.
Does the MAX14932AAWE+T support bidirectional communication?
No, the MAX14932AAWE+T is a unidirectional digital isolator with signal flow strictly from side A (INA1–INA4) to side B (OUTB1–OUTB4). It does not support bidirectional channels like I²C. For bidirectional isolation, Analog Devices recommends the MAX14933 family. The MAX14932AAWE+T's architecture eliminates contention risks and simplifies timing analysis in master-slave configurations such as SPI or RS-485 control lines.
What safety certifications does the MAX14932AAWE+T hold?
The MAX14932AAWE+T is certified to UL1577 (file E351759), CSA C22.2 No. 5A (cUL), and VDE 0884-11:2017-01 for basic insulation. It achieves 2.75kVRMS withstand voltage (60s), 443VRMS maximum working voltage, and 630VPK repetitive peak isolation voltage. These certifications validate its suitability for industrial equipment, medical devices (IEC 60601-1), and test & measurement instruments requiring reinforced insulation.
Can the MAX14932AAWE+T operate with different supply voltages on each side?
Yes, the MAX14932AAWE+T supports independent supply voltages from 1.71V to 5.5V on side A (VDDA/GNDA) and side B (VDDB/GNDB), enabling seamless level translation - for example, interfacing a 1.8V FPGA I/O bank to a 3.3V or 5V peripheral without external translators. Input thresholds scale with respective supplies (VIH = 0.7×VDD_, VIL = 0.6–0.8V), ensuring robust logic compatibility across mixed-voltage systems.
What is the meaning of the "AA" and "WE" in MAX14932AAWE+T?
In MAX14932AAWE+T, "AA" denotes the 150Mbps speed grade and default-low output configuration; "WE" specifies the 16-pin wide-body SOIC package (outline 21-0042, code W16M+8). The "+T" suffix indicates tape-and-reel packaging. This exact combination - 150Mbps, default-low, wide SOIC - distinguishes MAX14932AAWE+T from other variants like MAX14932BAWE+T (25Mbps) or MAX14932AASE+T (narrow SOIC).
