Product details
Overview
MAX14930DAWE+ 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 6.67ns minimum pulse width, <1ns pulse-width distortion at 5V, and operates from –40°C to +125°C - enabling robust signal isolation in industrial fieldbus, isolated SPI, and battery management systems.
For engineers reviewing the MAX14930DAWE+ datasheet, MAX14930DAWE+ pinout, MAX14930DAWE+ application, or MAX14930DAWE+ equivalent, this device delivers high-speed, low-jitter isolation with VDE-certified basic insulation, IEC 61000-4-5 ±10kV surge immunity, and configurable default-high output state for fail-safe system design.
Technical Context
The MAX14930DAWE+ implements capacitive isolation using Analog Devices' proprietary silicon-dioxide barrier technology, supporting unidirectional channel configuration (A→B only) with separate enable inputs (ENA/ENB) per side. Its architecture enables precise timing control with propagation delay skew as low as 0.9ns (channel-to-channel, same direction) and 2.8ns (part-to-part) at 5V supply.
It supports three data-rate variants (1/25/150Mbps); the "D" suffix denotes the 150Mbps version. The "A" variant indicates default-high output behavior when input is unpowered, and "W" specifies wide-body SOIC-16 package (10.3mm × 7.5mm) with 8mm creepage/clearance - certified to VDE 0884-11, UL1577, and CSA Bulletin 5A.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Isolation Rating | 2.75kVRMS withstand (60s), 443VRMS continuous working voltage - meets reinforced insulation requirements for industrial safety standards. |
| Max Data Rate | 150Mbps - supports high-speed serial interfaces like isolated SPI clock lines and fast digital I/O without timing bottlenecks. |
| Propagation Delay | 4.9–8.2ns (tPHL), 5.1–8.1ns (tPLH) - ensures sub-10ns latency critical for real-time control loops and time-sensitive communication. |
| CMTI | 25kV/µs - rejects fast common-mode transients in motor drives and power converters without output glitches. |
| Supply Range | 1.71V–5.5V on both sides - enables direct interfacing with 1.8V/2.5V/3.3V/5V microcontrollers and FPGAs without level shifters. |
| Default Output State | Default-high (A variant) - maintains known logic state during power-up, brown-out, or input disconnection for fail-safe operation. |
| Operating Temp | –40°C to +125°C - qualified for under-hood automotive, industrial PLC, and battery pack monitoring environments. |
Pinout & Package
Package: 16-pin wide-body SOIC (10.3mm × 7.5mm), RoHS-compliant, creepage/clearance ≥8mm, thermal resistance θJA = 71°C/W (4-layer board).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| INA1–INA4 | Primary-side input channels | Accept digital signals from VDDA domain; compatible with 1.71V–5.5V logic thresholds. |
| OUTB1–OUTB4 | Secondary-side isolated outputs | Drive loads referenced to GNDB; VOH = VDDB – 0.4V, VOL = 0.4V at 4mA sink/source. |
| VDDA / GNDA | Primary-side power and ground | Supply domain A: powers input circuitry and ENA; must be decoupled locally. |
| VDDB / GNDB | Secondary-side power and ground | Supply domain B: powers output drivers and ENB; galvanically isolated from VDDA/GNDA. |
| ENA / ENB | Channel enable inputs | Active-high enables output drivers; tri-state when low - allows bus sharing and power-gating. |
Key Features
| Feature | Design Value |
|---|---|
| Capacitive isolation barrier | 2.75kVRMS rating with 630VPK repetitive peak voltage - enables compact, high-reliability isolation without optocoupler aging or LED degradation. |
| Low-jitter timing performance | Peak eye diagram jitter ≤160ps at 1.8V - preserves signal integrity in high-speed serial links and clock distribution networks. |
| Configurable default output | Default-high (A variant) ensures defined logic state during power sequencing - eliminates need for external pull-ups in safety-critical paths. |
| High CMTI immunity | 25kV/µs common-mode transient rejection - prevents false triggering in noisy motor drive and inverter gate driver applications. |
| Dual-supply flexibility | Independent 1.71V–5.5V supplies per side - supports mixed-voltage systems (e.g., 1.8V FPGA core + 3.3V sensor interface) without external level translation. |

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, 150Mbps, 3.75kVRMS isolation, 2.5–5.5V supply, default-low output | Higher isolation rating but lacks default-high option; uses different enable logic (active-low EN) | Select when higher isolation voltage is required and default-low behavior aligns with system reset strategy. |
| ISO6741FDWR | 4-channel, 50Mbps, 5kVRMS, 1.71–5.5V, default-high, SOIC-16 narrow body | Lower max data rate (50Mbps vs. 150Mbps); narrower package (9.9mm × 3.9mm) with 4mm creepage | Choose for cost-sensitive designs needing 5kVRMS isolation where 50Mbps suffices and PCB space is constrained. |
Compared with SI8641ED-B-IS and ISO6741FDWR, the MAX14930DAWE+ uniquely combines 150Mbps speed, 2.75kVRMS isolation, default-high output, and wide-body SOIC packaging - making it optimal for high-speed industrial control where timing fidelity and fail-safe startup behavior are critical.

FAQ
What is the maximum data rate supported by the MAX14930DAWE+?
The MAX14930DAWE+ supports a maximum data rate of 150Mbps, verified across all supply voltages (1.71V–5.5V) and temperatures (–40°C to +125°C). This is confirmed in the Dynamic Electrical Characteristics table for MAX1493_B/E variants, where DRMAX = 150Mbps is explicitly specified for the "B" and "E" speed grades - and the "D" suffix in MAX14930DAWE+ identifies the 150Mbps version within the MAX14930 family.
Does the MAX14930DAWE+ support bidirectional communication?
No, the MAX14930DAWE+ is a unidirectional digital isolator with fixed A→B channel direction (inputs INA1–INA4, outputs OUTB1–OUTB4). Bidirectional operation (e.g., I²C) requires the MAX14933, which is explicitly called out in the General Description as the solution for bidirectional channel applications - confirming that MAX14930DAWE+ does not implement bidirectional logic or automatic direction sensing.
What does the "A" in MAX14930DAWE+ indicate?
The "A" in MAX14930DAWE+ denotes the default output state: default-high. As stated in the General Description, "Each device is also available in either a default high or default low configuration. The default is the state an output goes to when its input is unpowered." The "A" variant guarantees OUTB1–OUTB4 drive high when INA1–INA4 are unpowered or floating - a critical feature for fail-safe system initialization.
Is the MAX14930DAWE+ certified for medical applications?
Yes, the MAX14930DAWE+ is certified to IEC 60601-1 (ed. 3) for medical electrical equipment, as documented in the Safety Regulatory Approvals section under "TUV" and "IEC 60601-1 (ed. 3): For details, see Technical Report number 095-72100581-200." Its 630VPK repetitive peak isolation voltage and 443VRMS working voltage meet the requirements for 1 MOOP (Means of Patient Protection) in patient-connected devices.
What package type is used for the MAX14930DAWE+?
The MAX14930DAWE+ uses a 16-pin wide-body SOIC package (10.3mm × 7.5mm), identified by package code W16M+8 and outline number 21-0042. This is confirmed in the "Package Information" section, which lists "PACKAGE TYPE: 16 Wide SOIC" for the MAX14930–MAX14932 family and specifies 8mm creepage and clearance - distinguishing it from the narrow SOIC and QSOP variants used by other members of the family.
