Product details
Overview
MAX14930EASE+T 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 SPI bus isolation and battery management systems requiring high noise immunity.
For engineers reviewing the MAX14930EASE+T datasheet, MAX14930EASE+T pinout, MAX14930EASE+T application, or MAX14930EASE+T equivalent, this page delivers verified electrical specs (CMTI = 25kV/µs, tPLH/tPHL ≤ 8.2ns at 1.8V), package dimensions (16-pin wide SOIC, 10.3mm × 7.5mm), safety certifications (UL1577, VDE 0884-11 Basic Insulation), and real-world design context for multichannel isolation in harsh environments.
Technical Context
The MAX14930EASE+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 (A→B only) enables deterministic timing for SPI clock/data separation and RS-485 control signal isolation.
It integrates enable-controlled three-state outputs (tEN = 5.1ns typical, tTRI = 2.7ns typical at 4.5–5.5V), low-glitch rejection (15ns), and ultra-low propagation delay skew (≤0.9ns channel-to-channel same-direction at 5V), making it suitable for time-critical digital interfaces where deterministic latency and minimal jitter are required.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Isolation Rating | 2.75kVRMS withstand (60s), 443VRMS continuous working voltage - meets reinforced insulation requirements per IEC 60601-1 and IEC 61010-1. |
| Max Data Rate | 150Mbps - supports high-speed SPI, digital encoder feedback, and fast serial control links without oversampling or retiming. |
| Propagation Delay | tPLH/tPHL ≤ 8.2ns (1.71–1.89V), ≤7.5ns (4.5–5.5V) - enables sub-10ns timing budgets for synchronous protocols. |
| CMTI | 25kV/µs - rejects fast common-mode transients in motor drives, inverters, and power supply feedback loops. |
| Supply Range | 1.71V to 5.5V per side - allows direct interfacing with 1.8V FPGAs, 3.3V microcontrollers, and 5V legacy peripherals. |
| Operating Temp | –40°C to +125°C ambient - qualified for under-hood automotive, industrial PLC, and energy storage BMS applications. |
| Output Default | Low - ensures safe logic state during power-up/power-down sequences in fail-safe control systems. |
Pinout & Package
Package: 16-pin wide-body SOIC (10.3mm × 7.5mm, creepage/clearance = 8mm), RoHS-compliant, JEDEC MS-013AC outline.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| INA1–INA4 | Input signals (Side A) | Accept 1.71–5.5V logic; VIH = 0.7×VDDA, VIL ≤ 0.8V - compatible with CMOS/LVTTL drivers. |
| OUTB1–OUTB4 | Isolated output signals (Side B) | Drive loads up to 4mA; VOH = VDDB–0.4V, VOL ≤ 0.4V - supports direct connection to MCU GPIO or transceiver inputs. |
| VDDA / GNDA | Primary-side power & ground | Supplies input-side circuitry; independent of VDDB/GNDB - enables true galvanic domain separation. |
| VDDB / GNDB | Secondary-side power & ground | Supplies output-side circuitry; no shared reference - eliminates ground loop noise in sensor/actuator interfaces. |
| ENA / ENB | Enable controls (Side A/B) | Active-high enables; tEN = 5.1ns (5V), tTRI = 2.7ns - permits dynamic channel gating without added logic. |
Key Features
| Feature | Design Value |

| Glitch rejection | 15ns pulse rejection prevents false triggering from EFT bursts or switching noise in industrial environments. |
| Wide supply range per side | 1.71–5.5V operation on both sides eliminates external level shifters in mixed-voltage systems. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar digital isolator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADUM4401BRWZ | 4-channel, 100Mbps, 2.5kVRMS, default-high outputs, 16-pin SOIC (wide) | Limited to 100Mbps; lacks 150Mbps support and default-low option | Select when lower data rate suffices and default-high startup behavior is acceptable. |

FAQ
What is the isolation voltage rating of the MAX14930EASE+T?
The MAX14930EASE+T is rated for 2.75kVRMS withstand isolation voltage for 60 seconds (VISO), 443VRMS maximum working voltage (VIOWM), and 630VPK repetitive peak voltage (VIORM). It is certified to UL1577, VDE 0884-11 (Basic Insulation), and IEC 60601-1, supporting reinforced insulation in medical and industrial systems. These values are validated per IEC 60747-5-5.
Does the MAX14930EASE+T support bidirectional communication?
No, the MAX14930EASE+T is a unidirectional isolator - signals flow only from Side A (INA1–INA4) to Side B (OUTB1–OUTB4). For bidirectional applications like I²C, Analog Devices recommends the MAX14933. The MAX14930EASE+T's fixed A→B path ensures minimal propagation skew and deterministic timing for SPI, RS-485 control, and digital I/O isolation.
What are the supply voltage requirements for the MAX14930EASE+T?
The MAX14930EASE+T requires independent supplies: VDDA and GNDA on Side A (1.71V to 5.5V), and VDDB and GNDB on Side B (1.71V to 5.5V). This dual-supply flexibility enables level translation - e.g., 1.8V FPGA on Side A driving 3.3V ADC on Side B - without external translators. Undervoltage lockout activates below 1.45V.
How does the MAX14930EASE+T handle power-up sequencing?
The MAX14930EASE+T features a default-low output configuration: all OUTB pins drive low when their respective INA inputs are unpowered or floating. This failsafe behavior prevents unintended activation of downstream devices (e.g., MOSFET gates or transceiver enables) during power ramp-up or brownout conditions - a key requirement in battery management and industrial control systems.
What safety certifications does the MAX14930EASE+T hold?
The MAX14930EASE+T is certified to UL1577 (file E351759), cUL (CSA Bulletin 5A), VDE 0884-11:2017-01 (Basic Insulation), and TUV for IEC 60950-1, IEC 61010-1, and IEC 60601-1. It supports 1 MOOP and meets 630VPK transient voltage requirements - qualifying it for use in patient-connected medical equipment and industrial safety-rated subsystems.
