Product details
Overview
MAX14930BAWE+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 signal isolation in industrial fieldbus interfaces and battery management systems.
For engineers reviewing the MAX14930BAWE+T datasheet, MAX14930BAWE+T pinout, MAX14930BAWE+T application, or MAX14930BAWE+T equivalent, this device supports high-speed SPI/RS-485 isolation, level translation between mixed-voltage subsystems, and safety-critical I/O channel separation where creepage/clearance compliance and transient immunity are mandatory.
Technical Context
The MAX14930BAWE+T implements capacitive isolation using Analog Devices' proprietary process, delivering 25kV/µs common-mode transient immunity (CMTI) and supporting bidirectional enable control (ENA/ENB) for three-state output management. Its architecture separates side-A (INA1–INA4, VDDA, GNDA) and side-B (OUTB1–OUTB4, VDDB, GNDB) with no internal feedback path, ensuring true galvanic decoupling.
It supports all four channels in A→B direction only (unidirectional), with propagation delay skew as low as 0.9ns (channel-to-channel, same direction) at 5V supplies, and integrates undervoltage lockout (1.45V threshold) on both sides to prevent metastable output states during power ramp-up.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar digital isolator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ISO6741RWER | 4-channel, 5000VRMS, 50Mbps, 3.3V-only supply, default-high outputs | Limited to 3.3V systems; lower data rate restricts high-speed SPI use | Select when higher isolation voltage (5kVRMS) is required and 50Mbps suffices |
| ADUM2401BRWZ | 4-channel, 2500VRMS, 25Mbps, 3.0–5.5V supply, default-high outputs | Lower isolation rating and data rate; older iCoupler® technology with higher power consumption | Choose for legacy designs requiring pin compatibility with ADuM240x family and moderate speed needs |
Compared with ISO6741RWER and ADUM2401BRWZ, the MAX14930BAWE+T delivers 150Mbps throughput and 1.71V–5.5V dual-supply flexibility unmatched by either alternative - making it optimal for next-generation industrial and automotive systems demanding both speed and voltage interoperability.

FAQ
What is the maximum data rate supported by the MAX14930BAWE+T?
The MAX14930BAWE+T 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 enabled by its optimized capacitive isolation architecture and low-skew design, allowing reliable high-speed SPI, RS-485, and digital I/O isolation without external timing compensation. The 150Mbps rating applies specifically to the MAX14930BAWE+T variant, not the entire MAX14930–MAX14932 family.
Does the MAX14930BAWE+T support bidirectional communication?
No, the MAX14930BAWE+T is a unidirectional isolator with all four channels configured for side-A-to-side-B signal flow only (INA1–INA4 → OUTB1–OUTB4). For bidirectional applications such as I²C, Analog Devices specifies the MAX14933 family. The MAX14930BAWE+T includes independent ENA and ENB enable inputs to manage three-state behavior on each side, but does not provide reverse-path signal transmission capability.
What safety certifications does the MAX14930BAWE+T hold?
The MAX14930BAWE+T is certified to UL1577 (3750VRMS), CSA C22.2 No. 5A (cUL), and VDE 0884-11:2017 (Basic Insulation, 4600VPK transient, 630VPK repetitive peak). It also meets IEC 61010-1 and IEC 60601-1 for medical applications, with 443VRMS working voltage and 8mm creepage/clearance in its wide SOIC package - all confirmed in Analog Devices' certification file E351759 and TÜV technical reports.
Can the MAX14930BAWE+T operate with different supply voltages on each side?
Yes, the MAX14930BAWE+T supports independent 1.71V to 5.5V supplies on side-A (VDDA/GNDA) and side-B (VDDB/GNDB), enabling seamless level translation between disparate logic families - for example, interfacing a 1.8V FPGA I/O bank with a 5V microcontroller peripheral. This dual-supply capability is intrinsic to the device's architecture and requires no external components, unlike optocoupler-based solutions.
What is the output default state of the MAX14930BAWE+T?
MAX14930BAWE+T has a default-low output configuration: when any input (INA1–INA4) is unpowered or floating, the corresponding OUTB1–OUTB4 outputs drive low. This behavior is fixed for this specific part number (denoted by "B" in the suffix) and differs from the "A" (default-high) and "C" (mixed) variants in the MAX14930 family. It ensures fail-safe behavior in power-loss scenarios.
