Product details
Overview
MAX14930DASE+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 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 MAX14930DASE+T datasheet, MAX14930DASE+T pinout, MAX14930DASE+T application, or MAX14930DASE+T equivalent, this page delivers verified electrical specs, package mapping, safety certifications (UL, VDE, cUL), channel configuration details, and real-world design context for high-speed, high-temperature, multichannel isolation deployments.
Technical Context
The MAX14930DASE+T implements capacitive isolation using Analog Devices' proprietary process, supporting only unidirectional channel flow (A→B) with default-low output state. Its architecture delivers 25kV/µs common-mode transient immunity and sub-8ns propagation delay (tPLH/tPHL) at 5V supply, optimized for timing-critical interfaces like isolated ADC control or PLC backplane communication.
It supports three distinct data-rate variants (1/25/150Mbps); the "D" suffix in MAX14930DASE+T confirms the 150Mbps version. Channel enable inputs (ENA/ENB) provide independent side-gating, and logic-level compatibility across 1.71V–5.5V supplies enables direct interfacing with microcontrollers, FPGAs, and level-shifting applications without external translators.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Isolation Rating | 2.75kVRMS withstand (60s), 443VRMS working voltage - certified for basic insulation per VDE 0884-11 and UL1577. |
| Max Data Rate | 150Mbps - supports high-speed serial links such as isolated JESD204B auxiliary channels or fast sensor data aggregation. |
| Propagation Delay | 4.9–14.9ns (tPHL), 5.1–14ns (tPLH) - enables sub-10ns timing budgets for real-time control loop feedback paths. |
| Pulse-Width Distortion | <1ns (typical at 5V) - preserves signal integrity in clock distribution or PWM isolation where duty-cycle fidelity is critical. |
| Supply Range | 1.71V to 5.5V on both sides - allows direct connection to 1.8V FPGA I/O banks and 3.3V/5V MCU peripherals without level shifters. |
| CMTI | 25kV/µs - rejects fast transients in motor drives, inverters, and HV power supply monitoring without output glitches. |
| Operating Temp | –40°C to +125°C - qualified for under-hood automotive, industrial PLC, and downhole equipment environments. |
Pinout & Package
MAX14930DASE+T is housed in a 16-pin wide-body SOIC package (10.3mm × 7.5mm, 8mm creepage/clearance), RoHS-compliant, with exposed pad not present. Pin functions are validated per Analog Devices' functional diagram and absolute maximum ratings table.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

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, 5kVRMS isolation; 2.5–5.5V supply only; no 1.71V support. | Higher isolation rating suits mains-connected equipment; lacks ultra-low-voltage compatibility for battery-powered designs. | Select when >3.75kVRMS is mandated and 1.71V operation is unnecessary. |
| ISO6741FDWR | 4-channel, 50Mbps max, 5000VRMS; 1.71–5.5V supply; lower CMTI (100kV/µs claimed but not tested per IEC 61000-4-4/5). | Targeted at high-isolation, lower-speed applications (e.g., smart grid meters); not suitable for 150Mbps SPI or fast control loops. | Choose when 5kVRMS is required and data rate ≤50Mbps suffices; verify CMTI test methodology against system stress profiles. |
Compared with SI8641ED-B-IS and ISO6741FDWR, the MAX14930DASE+T uniquely combines 150Mbps speed, 2.75kVRMS rating, full 1.71V–5.5V dual-supply flexibility, and production-tested 25kV/µs CMTI - making it optimal for compact, high-speed, wide-temperature industrial and medical isolation where voltage scalability and transient robustness are co-critical.

FAQ
What is the isolation voltage rating of the MAX14930DASE+T?
The MAX14930DASE+T is rated for 2.75kVRMS withstand 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 cUL standards - confirming suitability for reinforced insulation in industrial and medical applications.
Does the MAX14930DASE+T support bidirectional communication?
No, the MAX14930DASE+T is a unidirectional isolator: signals pass only from Side A (INA1–INA4) to Side B (OUTB1–OUTB4). For bidirectional protocols like I²C, Analog Devices specifies the MAX14933 - a separate part with integrated bus arbitration logic. Using MAX14930DASE+T for I²C requires external direction control and is not recommended.
What is the default output state of the MAX14930DASE+T when unpowered?
The MAX14930DASE+T has a default-low output configuration. When the input side (Side A) is unpowered or floating, all OUTB1–OUTB4 outputs settle to logic low. This behavior is fixed by the "D" suffix in the part number and cannot be changed via external pins or configuration.
Can the MAX14930DASE+T operate at 1.71V on both sides simultaneously?
Yes, the MAX14930DASE+T supports 1.71V to 5.5V independently on VDDA and VDDB. At 1.71V, it maintains 150Mbps capability with typical propagation delay of 8.1–14.9ns and pulse-width distortion ≤1ns - enabling ultra-low-power isolated interfaces in battery-constrained edge nodes.
What safety certifications does the MAX14930DASE+T hold?
The MAX14930DASE+T holds UL1577 (E351759), cUL (CSA Bulletin 5A), VDE 0884-11 (basic insulation), TUV, and IEC 60601-1 (3rd ed.) certifications. It meets 443VRMS working voltage for basic insulation and is approved for 1 MOOP in medical applications per IEC 60601-1.
