Product details
Overview
MAX14930AASE+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 6.67ns minimum pulse width, <1ns pulse-width distortion at 5V, and operates from –40°C to +125°C - enabling robust SPI/RS-485 isolation in industrial motor drives and battery management systems.
For engineers reviewing the MAX14930AASE+T datasheet, MAX14930AASE+T pinout, MAX14930AASE+T application, or MAX14930AASE+T equivalent, this page delivers verified electrical specs, package mapping, functional channel configuration (A-side inputs → B-side outputs), safety certifications (UL, VDE, IEC), and real-world design context for high-noise industrial and medical isolation use cases.
Technical Context
The MAX14930AASE+T implements capacitive isolation with proprietary silicon-dioxide dielectric barriers, supporting asymmetric voltage operation (e.g., 1.8V on side A, 3.3V on side B) and level translation. Its unidirectional 4-channel architecture (INA1–INA4 → OUTB1–OUTB4) eliminates bidirectional contention, making it suitable for master-slave SPI interfaces where clock and data flow strictly from controller to peripheral.
It achieves 25kV/µs common-mode transient immunity (CMTI) and guarantees propagation delay skew ≤0.9ns (same-direction channels) at 5V supply - critical for timing-critical serial protocols. The device includes enable-controlled three-state outputs (tTRI = 2.7ns typical) and supports fail-safe default-low output behavior when input is unpowered.
Key Specifications
| Parameter | Value and Actual Design Meaning |

Pinout & Package
MAX14930AASE+T is housed in a 16-pin wide-body SOIC package (outline 21-0042, RoHS-compliant, W16M+8 code) with 8mm creepage and clearance, rated for 2.75kVRMS isolation. Pin numbering follows standard SOIC convention (pin 1 = dot-marked corner).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDDA | Primary-side power supply | Supplies logic side A (inputs INA1–INA4, ENA); accepts 1.71V–5.5V - enables low-voltage MCU interfacing. |
| GNDA | Primary-side ground reference | Reference for all side-A signals; must be isolated from GNDB by PCB layout and system grounding. |
| INA1–INA4 | Input channels (side A) | CMOS-compatible digital inputs accepting 0.7×VDDA high threshold; drive isolated outputs OUTB1–OUTB4. |
| ENA | Enable input (side A) | Active-high control for side-A outputs; tEN = 5.1ns typical - enables precise timing of output activation. |
| VDDB | Secondary-side power supply | Supplies logic side B (outputs OUTB1–OUTB4, ENB); independent 1.71V–5.5V domain enables level translation. |
| GNDB | Secondary-side ground reference | Reference for all side-B signals; galvanically isolated from GNDA - defines isolated domain boundary. |
| OUTB1–OUTB4 | Output channels (side B) | Push-pull CMOS outputs sinking/sourcing 4mA; VOH = VDDB–0.4V, VOL = 0.4V - compatible with 1.8V–5V logic families. |
| ENB | Enable input (side B) | Active-high control for side-B outputs; decouples side-B functionality during side-A initialization sequences. |
Key Features
| Feature | Design Value |
|---|---|
| Reinforced Isolation Barrier | Capacitive SiO₂ barrier certified to VDE 0884-11, UL1577, and IEC 60601-1 - supports 1 MOOP medical safety compliance. |
| Ultra-Low Propagation Skew | ≤0.9ns channel-to-channel skew (same direction) at 5V - ensures deterministic timing for multi-bit parallel data transfer. |
| Fail-Safe Default Output | Outputs go low when inputs are unpowered - prevents undefined states in power-loss scenarios for safety-critical systems. |
| High-Speed Enable Control | tTRI = 2.7ns typical (enable → three-state) - allows dynamic channel gating without introducing timing glitches. |
| Low-Power High-Speed Operation | 14.4mA total supply current at 150Mbps/3.3V - reduces thermal load in dense isolation stacks while maintaining speed. |

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, 1.7–5.5V supplies; lower CMTI (20kV/µs), no default-low option. | Qualified for industrial but not medical-grade isolation; lacks VDE 0884-11 certification. | Select when cost sensitivity outweighs medical certification needs and CMTI margin is sufficient. |
| ADUM4401BRWZ | 4-channel, 5kVRMS, 1Mbps max, 3.0–5.5V only; higher propagation delay (32ns), no 1.8V support. | Targeted at low-speed, high-isolation applications like PLC I/O modules - not suitable for high-speed SPI. | Choose only for legacy designs requiring >3.75kVRMS isolation at sub-Mbps rates; incompatible with 1.8V logic or 150Mbps timing. |
Compared with SI8641ED-IS and ADUM4401BRWZ, the MAX14930AASE+T uniquely combines medical-grade VDE/UL certification, 150Mbps speed, 1.8V compatibility, and fail-safe default-low behavior - making it the only option meeting full IEC 60601-1 requirements for high-speed isolated data acquisition in Class II devices.

FAQ
What is the maximum data rate supported by the MAX14930AASE+T?
The MAX14930AASE+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. At 5V supply, it achieves <1ns pulse-width distortion and 140ps peak eye diagram jitter - enabling reliable high-speed SPI communication without retiming logic. This performance is guaranteed by design and confirmed in the device's Dynamic Electrical Characteristics table.
Does the MAX14930AASE+T support different voltage levels on each side of the isolation barrier?
Yes, the MAX14930AASE+T supports independent 1.71V–5.5V supplies on side A (VDDA) and side B (VDDB), enabling true level translation. For example, it can interface a 1.8V FPGA I/O bank on side A with a 5V microcontroller on side B - eliminating external level shifters. Input thresholds scale with respective supplies (VIH = 0.7×VDD), and output drive strength remains consistent across the full voltage range.
What safety certifications does the MAX14930AASE+T hold?
The MAX14930AASE+T is certified to UL1577 (file E351759), cUL (CSA 5A), VDE 0884-11:2017-01 (basic insulation), and TUV-tested per IEC 60950-1, IEC 61010-1, and IEC 60601-1. It provides 2.75kVRMS withstand voltage, 443VRMS working voltage, and 1 MOOP medical safety rating - making it suitable for Class II medical devices and industrial test equipment requiring reinforced isolation.
How does the MAX14930AASE+T handle power loss on the input side?
The MAX14930AASE+T features a default-low output configuration: when side-A inputs (INA1–INA4) are unpowered or floating, the corresponding side-B outputs (OUTB1–OUTB4) drive low. This fail-safe behavior prevents undefined states in power-fail conditions - critical for safety interlocks in motor drives and emergency shutdown circuits. The default state is fixed per part number and cannot be changed via configuration pins.
What is the creepage and clearance distance of the MAX14930AASE+T package?
The MAX14930AASE+T uses a 16-pin wide-body SOIC package with 8mm minimum creepage and 8mm minimum clearance distances - exceeding IEC 60601-1 and IEC 61010-1 requirements for reinforced insulation at 443VRMS working voltage. These dimensions are achieved through internal mold compound geometry and leadframe design, and are validated per DIN VDE V 0884-11 Annex D.
