Product details
Overview
MAX14930FAWE+ from Analog Devices is a 4-channel, 2.75kVRMS galvanic digital isolator in a 16-pin wide-body SOIC package (10.3mm × 7.5mm), supporting unidirectional signal transfer between isolated power domains at up to +125°C ambient. It delivers 150Mbps data rate, 25kV/µs common-mode transient immunity, and operates with independent 1.71V–5.5V supplies on each side-enabling level translation in industrial SPI and RS-485 isolation.
For engineers reviewing the MAX14930FAWE+ datasheet, MAX14930FAWE+ pinout, MAX14930FAWE+ application, or MAX14930FAWE+ equivalent, this device is selected for high-speed, safety-certified multichannel isolation where VDE 0884-11 basic insulation, UL1577 2750VRMS rating, and sub-8ns propagation delay at 150Mbps are critical design requirements.
Technical Context
The MAX14930FAWE+ implements capacitive isolation using Maxim's proprietary process, with four independent unidirectional channels (A-side inputs → B-side outputs). Its architecture supports default-high output state and is optimized for low-jitter, high-CMTI operation across 1.71V–5.5V supply ranges on both sides.
It features integrated enable control (ENA/ENB), 6.67ns minimum pulse width tolerance, and peak eye diagram jitter of 140ps at 5V-making it suitable for timing-critical serial interfaces such as isolated high-speed SPI and digital I/O in battery management systems.

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, 16-pin narrow SOIC (9.9mm × 3.9mm); lower CMTI (20kV/µs) | Higher isolation rating but smaller package; less suited for high-noise industrial environments requiring >25kV/µs immunity | Prefer when board space is constrained and 5kVRMS certification is mandatory over CMTI margin |

FAQ
What is the maximum data rate supported by the MAX14930FAWE+?
The MAX14930FAWE+ 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 is confirmed in the Dynamic Electrical Characteristics table for MAX1493_B/E variants, where DRMAX = 150Mbps is explicitly specified with 6.67ns minimum pulse width and sub-8ns typical propagation delay at 5V.
Does the MAX14930FAWE+ support level translation between different voltage domains?
Yes, the MAX14930FAWE+ supports true bidirectional level translation via independent 1.71V–5.5V supplies on each side (VDDA and VDDB). Inputs accept logic thresholds scaled to their respective supply (VIH = 0.7×VDD), and outputs swing rail-to-rail relative to their local ground-enabling seamless interfacing between 1.8V microcontrollers and 3.3V or 5V peripherals without external translators.
What safety certifications does the MAX14930FAWE+ hold?
The MAX14930FAWE+ is certified to UL1577 (2750VRMS, file E351759), cUL (CSA Bulletin 5A), VDE 0884-11:2017-01 Basic Insulation (4600VPK transient, 630VPK repetitive peak), and IEC 61000-4-5 ±10kV surge. These are documented in the Safety Regulatory Approvals section and Insulation Characteristics tables of the official datasheet.
What is the propagation delay and jitter performance of the MAX14930FAWE+?
The MAX14930FAWE+ achieves 5.1ns typical propagation delay (tPLH) and 140ps peak eye diagram jitter at 5V supply, as specified in the Dynamic Electrical Characteristics for MAX1493_B/E variants. Pulse-width distortion is ≤1ns, and channel-to-channel skew is ≤0.9ns-critical for maintaining timing integrity in high-speed SPI and digital I/O applications.
Is the MAX14930FAWE+ pin-compatible with other devices in the MAX1493x family?
Yes, the MAX14930FAWE+ shares identical 16-pin wide-body SOIC pinout (W16M+8) and function mapping with all MAX14930–MAX14932 variants, including differing data-rate versions (1Mbps/25Mbps/150Mbps) and default-output configurations. Pin compatibility is confirmed in the Functional Diagram and Package Information sections of the datasheet.
