Product details
Overview
MAX14930FASE+T from Analog Devices is a 4-channel, unidirectional, 2.75kVRMS digital isolator in a 16-pin wide-body SOIC package (10.3mm × 7.5mm), supporting up to 150Mbps data rate, 25kV/µs CMTI, and dual 1.71V–5.5V supplies for level translation. It enables isolated SPI, RS-485, and industrial I/O in fieldbus systems operating from –40°C to +125°C.
For engineers reviewing the MAX14930FASE+T datasheet, MAX14930FASE+T pinout, MAX14930FASE+T application, or MAX14930FASE+T equivalent, this page delivers verified isolation parameters, channel configuration details, safety certifications (UL, VDE, cUL), thermal derating curves, and real-world design constraints for high-reliability industrial and medical systems.
Technical Context
The MAX14930FASE+T implements capacitive galvanic isolation with proprietary dielectric barrier technology, delivering 2.75kVRMS withstand voltage (60s) and 443VRMS continuous working voltage (VIOWM). Its architecture supports asymmetric supply operation - VDDA and VDDB independently configurable from 1.71V to 5.5V - enabling bidirectional level shifting across isolated domains without external translators.
It features four unidirectional channels with default-low output state (suffix "F"), optimized for SPI master-to-slave or sensor-to-processor isolation. Propagation delay skew is ≤0.9ns (same-direction channels) and ≤7.1ns (opposing-direction), with <1ps pulse-width distortion at 150Mbps, ensuring timing-critical signal integrity in high-speed industrial interfaces.

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, 5kVRMS, 150Mbps, 1.7–5.5V supplies; uses silicon-dioxide isolation; slightly higher propagation delay (10.5ns typ) | Higher isolation rating suits mains-connected equipment; lower CMTI (15kV/µs) limits use in high-dv/dt motor drives | Select when 5kVRMS certification (e.g., IEC 61800-5-1) is mandatory and 25kV/µs CMTI is not required. |
| ISO6741FDWR | 4-channel, 5000VRMS, 50Mbps, 1.71–5.5V; capacitive isolation; integrated LDO on secondary side | LDO simplifies secondary-side power but adds quiescent current; 50Mbps limit excludes high-speed SPI or fast serial links | Choose when secondary-side power regulation is needed and data rate ≤50Mbps suffices - reduces BOM count vs. discrete LDO. |
Compared with SI8641ED-B-IS and ISO6741FDWR, the MAX14930FASE+T delivers superior transient noise immunity (25kV/µs CMTI) and tighter timing control (≤0.9ns skew), making it optimal for high-speed industrial communications where signal integrity under electrical stress is critical - without requiring secondary-side regulation or exceeding 150Mbps throughput.

FAQ
What is the maximum data rate supported by the MAX14930FASE+T?
The MAX14930FASE+T supports a maximum data rate of 150Mbps, verified across its full operating temperature range (–40°C to +125°C) and supply voltage range (1.71V to 5.5V). This performance is achieved with minimal pulse-width distortion (<1ns) and tight channel-to-channel skew (≤0.9ns), making the MAX14930FASE+T suitable for high-speed isolated SPI, digital I/O, and sensor interface applications where timing precision is critical.
Does the MAX14930FASE+T support independent voltage supplies on each side?
Yes, the MAX14930FASE+T supports fully independent 1.71V to 5.5V supplies on both the primary (VDDA/GNDA) and secondary (VDDB/GNDB) sides. This enables true level translation - for example, interfacing a 1.8V FPGA on Side A with a 5V RS-485 transceiver on Side B - without external level shifters. The MAX14930FASE+T maintains specified timing and isolation performance across all valid supply combinations.
What safety certifications does the MAX14930FASE+T hold?
The MAX14930FASE+T is certified to UL 1577 (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 requirements for working voltage (443VRMS) and creepage (8mm), enabling use in industrial control panels and Class II medical devices without additional safety validation.
What is the default output state of the MAX14930FASE+T?
The MAX14930FASE+T has a default-low output configuration (denoted by the "F" suffix), meaning all four OUTB outputs drive logic-low when their respective INA inputs are unpowered or floating. This fail-safe behavior prevents unintended activation of downstream drivers, relays, or transceivers during power sequencing or fault conditions - a key requirement in industrial and medical safety-critical designs using the MAX14930FASE+T.
How does the MAX14930FASE+T handle common-mode transients?
The MAX14930FASE+T achieves a minimum common-mode transient immunity (CMTI) of 25kV/µs, measured per IEC 60747-5-5 with 1000V common-mode step applied between GNDA and GNDB. This high CMTI rating ensures reliable operation in electrically noisy environments such as motor drives, inverters, and switch-mode power supplies - preventing data corruption or output glitches that could occur with lower-rated isolators.
