Product details
Overview
MAX14932EASE+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 - enabling robust signal isolation in industrial fieldbus and battery management systems.
For engineers reviewing the MAX14932EASE+T datasheet, MAX14932EASE+T pinout, MAX14932EASE+T application, or MAX14932EASE+T equivalent, this device delivers high-speed, low-jitter isolation for SPI/RS-485 interfaces where safety-rated insulation, wide supply voltage compatibility, and channel-to-channel skew <1.6ns are critical design requirements.
Technical Context
The MAX14932EASE+T implements capacitive isolation using Analog Devices' proprietary process, supporting only unidirectional channel flow (A→B or B→A per channel pair) - unlike bidirectional variants such as MAX14933. Its architecture enables precise timing control with propagation delay skew ≤1.6ns (channel-to-channel, same direction) and CMTI ≥25kV/µs, ensuring noise immunity in noisy industrial environments.
It integrates enable-controlled three-state outputs (tEN = 5.1ns typical at 5V), supports level translation between disparate logic domains, and meets IEC 60747-5-5 insulation standards including VDE 0884-11 Basic Insulation, UL1577, and CSA Bulletin 5A certification - all validated at 2.75kVRMS withstand voltage for 60 seconds.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Isolation Rating | 2.75kVRMS for 60s (UL/VDE certified); enables use in reinforced insulation systems up to 443VRMS working voltage. |
| Max Data Rate | 150Mbps - supports high-speed SPI clocking and real-time sensor data transfer without protocol bottlenecks. |
| Propagation Delay Skew | ≤1.6ns (same-direction channels) - ensures deterministic timing alignment across all four isolated signals. |
| Supply Voltage Range | 1.71V to 5.5V per side - allows direct interfacing with 1.8V microcontrollers and 5V legacy peripherals without level shifters. |
| Common-Mode Transient Immunity | ≥25kV/µs - maintains signal integrity during fast transients common in motor drives and power converters. |
| Operating Temperature | –40°C to +125°C - qualified for under-hood automotive, industrial PLC, and medical equipment applications. |
| Peak Eye Jitter | 160ps max at 1.8V - preserves signal integrity at high data rates in noise-sensitive communication links. |
Pinout & Package
MAX14932EASE+T is housed in a 16-pin wide-body SOIC package (10.3mm × 7.5mm, 8mm creepage/clearance), optimized for high-voltage isolation compliance and thermal performance (θJA = 71°C/W on 4-layer board).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| INA1–INA4 | Primary-side input channels | Accept digital signals referenced to GNDA; compatible with 1.71V–5.5V logic levels. |
| INB1–INB4 | Secondary-side input channels | Accept digital signals referenced to GNDB; support independent voltage domain interfacing. |
| OUTA1–OUTA4 | Primary-side isolated outputs | Drive loads referenced to GNDA; default-low behavior when ENA is inactive. |
| OUTB1–OUTB4 | Secondary-side isolated outputs | Drive loads referenced to GNDB; default-low behavior when ENB is inactive. |
| ENA / ENB | Output enable controls | Active-high enables respective output banks; tEN = 5.1ns (typ) enables fast channel gating. |
| VDDA / VDDB | Isolated power supplies | Independent 1.71V–5.5V supplies per side - essential for level translation and fault containment. |
| GNDA / GNDB | Isolated ground references | Physically separated grounds maintain galvanic barrier integrity and prevent ground-loop currents. |
Key Features
| Feature | Design Value |
|---|---|
| 150Mbps high-speed isolation | Enables real-time SPI and RS-485 communication without data-rate compromise in isolated subsystems. |
| 1.6ns channel-to-channel skew | Guarantees synchronized timing across all four channels - critical for parallel data bus isolation. |
| 25kV/µs CMTI | Prevents false triggering in high-noise environments like motor inverters and industrial power supplies. |
| Default-low output state | Ensures safe, known logic state during power-up, brown-out, or input float conditions. |
| 8mm creepage & clearance | Meets reinforced insulation requirements for 300–400VAC working voltages per IEC 61010-1. |
| 1.71V–5.5V dual-supply flexibility | Eliminates external level shifters when bridging 1.8V FPGAs to 5V analog front-ends or sensors. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar digital isolator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SI8642ED-IS | 4-channel, 2.5kVRMS, 150Mbps, default-high outputs; uses silicon dioxide isolation; 16-pin narrow SOIC (4mm creepage). | Limited to 2.5kVRMS and 4mm creepage - unsuitable for 300VRMS+ working voltage or reinforced insulation systems. | Select when cost sensitivity outweighs creepage requirement and default-high logic is acceptable. |
| ISO6741FQDWR | 4-channel, 5kVRMS, 50Mbps, default-low outputs; uses capacitive isolation; 16-pin SOIC with 8mm creepage. | Lower 50Mbps data rate limits use in high-speed SPI or RS-485; higher 5kVRMS rating suits medical/AES applications. | Choose when higher isolation voltage is mandatory but data rate ≤50Mbps suffices. |
Compared with SI8642ED-IS and ISO6741FQDWR, the MAX14932EASE+T uniquely combines 2.75kVRMS isolation, 150Mbps speed, 8mm creepage, and default-low outputs - making it optimal for industrial SPI isolation where both speed and safety margin are non-negotiable.

FAQ
What is the isolation voltage rating of the MAX14932EASE+T?
The MAX14932EASE+T is rated for 2.75kVRMS withstand voltage for 60 seconds per UL1577 and VDE 0884-11, with a maximum repetitive peak isolation voltage (VIORM) of 630VPK and continuous working voltage (VIOWM) of 443VRMS - certified for basic insulation in industrial and medical applications.
Does the MAX14932EASE+T support bidirectional communication?
No, the MAX14932EASE+T is a unidirectional digital isolator. It supports only one-way signal flow per channel (either A→B or B→A). For bidirectional protocols like I²C, Analog Devices recommends the MAX14933 instead.
What is the default output state of the MAX14932EASE+T?
The MAX14932EASE+T has a default-low output configuration: when its input is unpowered or floating, each output assumes a logic-low state. This behavior is confirmed in the datasheet's Product Selector Guide and applies to both OUTA and OUTB banks.
Can the MAX14932EASE+T operate with different supply voltages on each side?
Yes, the MAX14932EASE+T supports independent 1.71V to 5.5V supplies on VDDA and VDDB - enabling seamless level translation between, for example, a 1.8V FPGA core and a 3.3V RS-485 transceiver without external level shifters.
