Product details
Overview
MAX14930EAWE+ from Analog Devices is a 4-channel, unidirectional digital isolator with 2.75kVRMS galvanic isolation, 150Mbps maximum 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 - deployed in industrial fieldbus interfaces and isolated SPI/RS-485 systems requiring high-speed, robust signal integrity.
For engineers reviewing the MAX14930EAWE+ datasheet, MAX14930EAWE+ pinout, MAX14930EAWE+ application, or MAX14930EAWE+ equivalent, this page delivers verified electrical specs (CMTI = 25kV/µs, tPLH/tPHL ≤ 7.5ns at 5V), package mapping (16-pin wide SOIC, 10.3mm × 7.5mm), safety certifications (UL1577, VDE 0884-11 Basic Insulation), and real-world substitution guidance for multichannel isolation design.
Technical Context
The MAX14930EAWE+ implements capacitive isolation using Maxim's proprietary process, supporting only unidirectional channel flow (A→B) with dedicated enable inputs (ENA/ENB) per side. Its architecture delivers deterministic timing: propagation delay skew < 1ns (channel-to-channel, same direction) and < 8ns (opposing direction) at 5V supply, enabling precise synchronization in high-speed serial links.
It supports level translation between mismatched logic domains (e.g., 1.8V microcontroller to 3.3V FPGA I/O) via independent VDDA/GNDA and VDDB/GNDB supplies. Input hysteresis (410mV) and ±4kV HBM ESD protection ensure noise immunity in electrically noisy industrial environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Isolation Rating | 2.75kVRMS withstand (60s), 443VRMS continuous working voltage - meets basic insulation requirements per VDE 0884-11 and UL1577. |
| Max Data Rate | 150Mbps - enables high-throughput isolated communication in modern industrial Ethernet and servo drive control loops. |
| Propagation Delay | 5.1ns (tPLH) / 4.9ns (tPHL) typical at 5V - ensures sub-10ns latency critical for real-time feedback systems. |
| CMTI | 25kV/µs - rejects fast common-mode transients induced by motor switching or relay bounce in factory automation. |
| Supply Range | 1.71V to 5.5V on both sides - allows direct interfacing with legacy 5V logic and ultra-low-power 1.8V MCUs without level shifters. |
| Operating Temp | –40°C to +125°C ambient - qualified for under-hood automotive subsystems and industrial PLC backplanes. |
| Output Default | Low-state default - prevents undefined logic states during power-up or input float conditions in safety-critical I/O modules. |
Pinout & Package
Package: 16-pin wide-body SOIC (W16M+8), 10.3mm × 7.5mm footprint, 8mm creepage/clearance, RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| INA1–INA4 | Primary-side digital inputs | Accept CMOS/TTL signals referenced to GNDA; VIH = 0.7×VDDA, VIL = 0.8V (for VDDA ≥ 2.25V). |
| OUTB1–OUTB4 | Secondary-side isolated outputs | Drive CMOS loads up to –4mA/0.4V VOL; VOH = VDDB – 0.4V at –4mA sink. |
| VDDA, GNDA | Primary-side power domain | Supplies input side and internal logic; independent of secondary domain - enables level translation. |
| VDDB, GNDB | Secondary-side power domain | Supplies output drivers and isolation barrier receiver; decoupling required per datasheet layout guidelines. |
| ENA, ENB | Channel enable controls | Active-high enables output drivers; tri-states OUTBx when low - supports dynamic power gating and bus arbitration. |
Key Features
| Feature | Design Value |
|---|---|
| Capacitive isolation barrier | 2pF inter-side capacitance - minimizes high-frequency coupling and preserves signal integrity in mixed-signal systems. |
| Ultra-low propagation skew | ≤0.9ns channel-to-channel (same direction) at 5V - enables synchronous sampling across multiple isolated ADC channels. |
| Glitch rejection | 15ns minimum pulse rejection - suppresses EMI-induced narrow spikes that could corrupt control signals in motor drives. |
| Peak eye diagram jitter | 140ps at 5V supply - ensures clean signal eye opening for reliable 150Mbps NRZ data recovery in SERDES links. |
| Safety-certified insulation | VIOTM = 4600VPK transient rating - validated for use in medical equipment (IEC 60601-1) and industrial safety controllers. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar digital isolator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SI8641ED-IS | 4-channel, 2.5kVRMS, 150Mbps, default-high output; uses silicon dioxide isolation; 16-pin narrow SOIC (9.9mm × 3.9mm). | Smaller footprint but lower isolation rating; lacks 443VRMS continuous working voltage rating per IEC 61010-1. | Select when board space is constrained and 2.5kVRMS suffices; verify creepage compliance for end-equipment safety standards. |
| ADUM4401BRWZ | 4-channel, 5kVRMS, 1Mbps, default-high; uses iCoupler magnetic isolation; 16-pin wide SOIC (10.3mm × 7.5mm). | Higher isolation but 150× slower data rate; higher propagation delay (32ns typ); not suitable for >10Mbps SPI or RS-485. | Select only for ultra-high-isolation, low-speed applications like mains monitoring where speed is secondary to safety margin. |
Compared with SI8641ED-IS and ADUM4401BRWZ, the MAX14930EAWE+ uniquely balances 2.75kVRMS isolation, 150Mbps speed, and default-low output in a standard wide SOIC - making it optimal for high-speed industrial communications where both safety and bandwidth are non-negotiable.

FAQ
What is the isolation voltage rating of the MAX14930EAWE+?
The MAX14930EAWE+ is rated for 2.75kVRMS withstand isolation voltage for 60 seconds (VISO), 443VRMS continuous working voltage (VIOWM), and 630VPK repetitive peak voltage (VIORM). These values are certified per UL1577, VDE 0884-11, and IEC 60950-1 - confirming suitability for basic insulation in industrial and medical equipment.
Does the MAX14930EAWE+ support bidirectional communication?
No, the MAX14930EAWE+ is a unidirectional isolator with fixed A→B signal flow (INAx → OUTBx). For bidirectional protocols like I²C, Analog Devices specifies the MAX14933 family. The MAX14930EAWE+ requires separate forward/reverse channel pairs or complementary devices for full-duplex isolation.
What is the meaning of "EAWE+" in MAX14930EAWE+?
The suffix "EAWE+" denotes a specific variant: "E" = 150Mbps data rate, "A" = default-low output configuration, "W" = wide-body SOIC package (10.3mm × 7.5mm), "E" = lead-free/RoHS-compliant, and "+" = tape-and-reel packaging. This matches the W16M+8 package code in the datasheet.
Can the MAX14930EAWE+ operate with different supply voltages on each side?
Yes - the MAX14930EAWE+ supports independent 1.71V to 5.5V supplies on VDDA/GNDA (primary side) and VDDB/GNDB (secondary side). This enables seamless level translation, such as interfacing a 1.8V FPGA I/O bank with a 3.3V isolated ADC, without external level shifters.
What safety certifications does the MAX14930EAWE+ hold?
The MAX14930EAWE+ is certified to UL1577 (file E351759), CSA C22.2 No. 5A (cUL), VDE 0884-11:2017-01 (basic insulation), and TUV for IEC 60950-1, IEC 61010-1, and IEC 60601-1. It provides 1 MOOP patient protection rating and meets 8mm creepage/clearance requirements in wide SOIC packaging.
