Product details
Overview
MAX14930BAWE+ 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, 25kV/µs common-mode transient immunity, and operates from –40°C to +125°C - enabling robust signal isolation in industrial fieldbus and battery management systems.
For engineers reviewing the MAX14930BAWE+ datasheet, MAX14930BAWE+ pinout, MAX14930BAWE+ application, or MAX14930BAWE+ equivalent, this page delivers verified electrical specs, package mapping, functional channel assignment, safety certification details (UL, VDE, cUL), and real-world design context for high-reliability multichannel isolation deployments.
Technical Context
The MAX14930BAWE+ implements capacitive isolation using Maxim's proprietary process, supporting only unidirectional channel flow (A→B) with no bidirectional capability. Its architecture includes integrated enable inputs (ENA/ENB) per side, allowing three-state control of outputs, and supports all four channels operating independently at up to 150Mbps with sub-8ns propagation delay (tPLH/tPHL) at 5V supplies.
It meets IEC 60747-5-5 insulation requirements with VIOWM = 443VRMS continuous working voltage, VIORM = 630VPK repetitive peak, and withstands ±10kV surge per IEC 61000-4-5. The device is certified to UL1577 (3750VRMS), VDE 0884-11 (Basic Insulation), and TUV standards - confirming suitability for medical and industrial safety-critical 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, 2.5kVRMS, 100Mbps, default-high outputs, 16-pin SOIC (wide) | Lacks 150Mbps speed and 25kV/µs CMTI; uses iCoupler magnetic isolation | Select when lower cost and legacy ADI ecosystem compatibility outweigh need for max speed/surge immunity |
| SI8642ED-B-IS | 4-channel, 5kVRMS, 150Mbps, default-low, 16-pin SOIC (narrow) | Higher isolation rating but narrower package (4mm creepage); different enable timing (tEN = 12ns typ) | Choose for space-constrained designs needing 5kVRMS reinforcement, accepting tighter layout constraints |
Compared with ADUM4402BRWZ and SI8642ED-B-IS, the MAX14930BAWE+ uniquely combines 2.75kVRMS rating, 150Mbps speed, default-low outputs, and 25kV/µs CMTI in a wide SOIC package - making it optimal for high-noise industrial control where timing fidelity and fail-safe behavior are critical.

FAQ
What is the maximum data rate supported by the MAX14930BAWE+?
The MAX14930BAWE+ supports a maximum data rate of 150Mbps, verified across its full 1.71V–5.5V supply range and –40°C to +125°C operating temperature. This performance is achieved with <1ns pulse-width distortion and <1.6ns channel-to-channel skew at 5V, enabling reliable high-speed SPI and digital control signal isolation in time-critical applications.
Does the MAX14930BAWE+ support bidirectional communication?
No, the MAX14930BAWE+ is a unidirectional digital isolator with fixed A→B channel direction only. It does not support bidirectional protocols like I²C. For bidirectional isolation, Analog Devices recommends the MAX14933 family. The MAX14930BAWE+'s channel mapping is strictly input (INA1–INA4) on side A and output (OUTB1–OUTB4) on side B.
What safety certifications does the MAX14930BAWE+ hold?
The MAX14930BAWE+ is certified to UL1577 (3750VRMS), CSA/cUL (3750VRMS), VDE 0884-11:2017 (Basic Insulation), and TUV standards. It meets IEC 61010-1 and IEC 60601-1 ed.3 requirements with 443VRMS working voltage and 4600VPK transient rating - qualifying it for industrial and Class II medical equipment.
What is the default output state of the MAX14930BAWE+?
The MAX14930BAWE+ has a default-low output configuration: when any input (INAx) is unpowered or floating, the corresponding output (OUTBx) defaults to logic low. This fail-safe behavior prevents unintended activation in safety-critical systems such as battery disconnect controllers or motor enable circuits.
How does the MAX14930BAWE+ handle common-mode transients?
The MAX14930BAWE+ achieves 25kV/µs common-mode transient immunity (CMTI), measured per IEC 60747-5-5 with 1000V common-mode step applied between GNDA and GNDB. This performance ensures error-free signal transmission in high-noise environments like variable-frequency drives and switch-mode power supplies without output glitches or latch-up.
