Product details
Overview
MAX14932BAWE+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 - enabling robust SPI/RS-485 isolation in industrial motor drives and battery management systems.
For engineers reviewing the MAX14932BAWE+T datasheet, MAX14932BAWE+T pinout, MAX14932BAWE+T application, or MAX14932BAWE+T equivalent, this page delivers verified electrical specs, safety-certified isolation parameters, package dimensions, functional pin roles, and real-world design context for high-reliability multichannel isolation deployment.
Technical Context
The MAX14932BAWE+T implements capacitive isolation using Analog Devices' proprietary process, supporting only unidirectional channel flow (A→B) with dedicated enable inputs (ENA/ENB) per side. Its architecture delivers 25kV/µs common-mode transient immunity and <1ns pulse-width distortion at 150Mbps, ensuring signal integrity in noisy industrial environments.
It supports three distinct data-rate variants (1/25/150Mbps); the "B" suffix denotes the 150Mbps version. The "AWE+T" package code specifies a 16-pin wide-body SOIC (10.3mm × 7.5mm) with 8mm creepage/clearance, UL/VDE-certified basic insulation, and RoHS-compliant lead finish.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Isolation Rating | 2.75kVRMS withstand (60s), 443VRMS continuous working voltage - meets IEC 60601-1 & IEC 61010-1 safety requirements for medical and test equipment. |
| Data Rate | 150Mbps maximum - enables high-speed isolated communication in servo controllers and real-time PLC backplanes. |
| Propagation Delay | 4.9–14.9ns (tPHL/tPLH, VDD = 1.8–5.5V) - ensures sub-15ns timing budgets for deterministic control loops. |
| Common-Mode Transient Immunity | 25kV/µs - suppresses fast transients from IGBT switching noise in motor inverters without signal corruption. |
| Supply Voltage Range | 1.71V to 5.5V per side - allows direct interfacing with 1.8V FPGAs and 3.3V/5V microcontrollers without level shifters. |
| Output Default State | Low - prevents undefined logic states during power-up or input float in safety-critical sensor interfaces. |
| Operating Temperature | –40°C to +125°C - qualified for under-hood automotive ECUs and industrial fieldbus nodes. |
Pinout & Package
Package: 16-pin wide-body SOIC (10.3mm × 7.5mm), 8mm creepage/clearance, RoHS-compliant, JEDEC MS-013AC outline.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| INA1–INA4 | Primary-side input channels | Accept CMOS/LVTTL signals referenced to GNDA; VIH = 0.7×VDDA, VIL = 0.6–0.8V. |
| OUTB1–OUTB4 | Secondary-side isolated outputs | Drive CMOS loads up to 4mA; VOH = VDDB–0.4V, VOL = 0.4V, compatible with 1.8–5.5V logic. |
| ENA | Primary-side output enable | Active-high; disables OUTAx when low (three-state), critical for bus arbitration in shared isolated buses. |
| ENB | Secondary-side output enable | Active-high; disables OUTBx when low - enables bidirectional bus control across isolation barrier. |
| VDDA / GNDA | Primary-side power/ground | Supplies isolated input side; supports 1.71–5.5V; UVLO threshold = 1.45–1.71V. |
| VDDB / GNDB | Secondary-side power/ground | Supplies isolated output side; independent supply domain enables level translation between voltage domains. |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar digital isolator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ISO6741QDWR | 4-channel, 5000VRMS, 50Mbps, 16-pin SOIC, TI's capacitive isolator | Higher isolation rating but lower speed; lacks 150Mbps capability and default-low option | Select when 5kVRMS is mandatory and data rate ≤50Mbps suffices - e.g., HVDC protection relays. |
| ADUM141DBRZ | 4-channel, 3750VRMS, 150Mbps, 16-pin SOIC, Analog Devices' iCoupler® | Same speed and package; uses magnetic coupling, higher CMTI (75kV/µs), no default-low option | Choose for extreme EMI environments (e.g., MRI subsystems) where magnetic isolation provides superior noise rejection. |
Compared with ISO6741QDWR and ADUM141DBRZ, the MAX14932BAWE+T uniquely combines 150Mbps speed, 2.75kVRMS isolation, default-low outputs, and 25kV/µs CMTI in a single wide-SOIC device - making it optimal for cost-sensitive, high-speed industrial automation where precise power-up behavior is required.

FAQ
What is the maximum data rate supported by the MAX14932BAWE+T?
The MAX14932BAWE+T supports a maximum data rate of 150Mbps, verified across its full operating voltage range (1.71V–5.5V) and temperature range (–40°C to +125°C). This performance is specified in the Dynamic Electrical Characteristics table for the MAX1493_B/E variant, confirmed by propagation delay (tPLH/tPHL ≤14.9ns) and minimum pulse width (6.67ns) metrics in the official Analog Devices datasheet.
Does the MAX14932BAWE+T support bidirectional communication?
No, the MAX14932BAWE+T is a unidirectional digital isolator - signals flow only from the A-side (INA1–INA4) to the B-side (OUTB1–OUTB4). For bidirectional applications such as I²C, Analog Devices specifies the MAX14933 family; the MAX14932BAWE+T's pinout and functional diagram confirm dedicated input and output banks with no reverse-path capability.
What safety certifications does the MAX14932BAWE+T hold?
The MAX14932BAWE+T is certified to UL 1577 (3750VRMS), CSA C22.2 No. 5A (3750VRMS), VDE 0884-11:2017 (basic insulation, 4600VPK transient), and TÜV IEC 60950-1/61010-1/60601-1. These approvals cover 2.75kVRMS withstand voltage, 443VRMS working voltage, and 630VPK repetitive peak voltage - documented in the Safety Regulatory Approvals section of the datasheet.
What is the meaning of the "B" and "AWE+T" suffixes in MAX14932BAWE+T?
The "B" suffix identifies the 150Mbps data-rate variant within the MAX14932 family. "AWE+T" denotes the 16-pin wide-body SOIC package (AWE = 10.3mm × 7.5mm, 8mm creepage), tape-and-reel packaging (+T), and RoHS-compliant finish. This mapping is defined in the Package Information section and Ordering Guide of the MAX14930–MAX14932 datasheet.
How does the default-low output configuration of the MAX14932BAWE+T improve system safety?
The MAX14932BAWE+T's default-low output state ensures that all OUTB1–OUTB4 pins drive logic-low when their corresponding INA inputs are unpowered or floating - preventing unintended activation of downstream drivers, relays, or gate circuits during power sequencing or fault conditions. This behavior is explicitly specified in the General Description and Product Selector Guide, and is critical for fail-safe operation in SIL-2–compliant industrial controls.
