Product details
Overview
MAX14936AAWE+T from Maxim Integrated is a four-channel, unidirectional 5kVRMS digital isolator with 150Mbps data rate, default-low output configuration, and independent 1.71V–5.5V dual-supply operation across isolated domains. It provides galvanic isolation for SPI, RS-485, and multichannel I/O in industrial fieldbus and battery management systems.
For engineers reviewing the MAX14936AAWE+T datasheet, MAX14936AAWE+T pinout, MAX14936AAWE+T application, or MAX14936AAWE+T equivalent, this page delivers verified electrical specs, channel mapping, safety certifications (UL, VDE, IEC), thermal derating curves, and real-world isolation use cases - all confirmed for the exact MAX14936AAWE+T variant.
Technical Context
The MAX14936AAWE+T implements capacitive isolation with proprietary silicon-dioxide barrier technology, supporting asymmetric voltage operation (e.g., 1.8V on Side A, 3.3V on Side B) and level translation. Its 150Mbps capability enables high-speed serial interface isolation without external timing components.
It features active-high enable inputs (ENA/ENB) with internal 2µA pullups, 25kV/µs common-mode transient immunity, and propagation delay skew as low as 0.9ns (same-direction channels). The device operates over –40°C to +125°C ambient and is production-tested at full temperature range.
Key Specifications

Pinout & Package
Package: 16-pin wide-body SOIC (W16M+8), 10.3mm × 7.5mm body, 2.65mm height, RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 16 | VDDA / VDDB | Independent logic-side (A) and field-side (B) power supplies - each requires local 0.1µF ceramic bypass |
| 2, 8, 9, 15 | GNDA / GNDB | Separate ground references for isolated domains - no shared ground connection permitted |
| 3–6 | INA1–INA4 | Unidirectional input channels on Side A - drive corresponding OUTB1–OUTB4 outputs across isolation barrier |
| 11–14 | OUTB1–OUTB4 | Unidirectional output channels on Side B - default-low state when INAx is unpowered or ENB inactive |
| 7, 10 | ENA / ENB | Active-high enable controls - internal 2µA pullup ensures defined output state during power-up sequencing |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar digital isolator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADUM4402BRIZ | 4-channel, 100Mbps, 2.5kVRMS isolation, 3.3V-only supply, no default-low option | Limited to lower-voltage industrial systems; lacks 150Mbps speed and dual-supply flexibility | Choose when cost sensitivity outweighs speed and supply range requirements |
| SI8642ED-B-IS | 4-channel, 150Mbps, 5kVRMS, 2.5–5.5V supply, but only default-high output configuration | Requires external pull-down resistors for safe-low behavior during power loss | Choose when default-high is acceptable and VDE certification is not mandatory |
Compared with ADUM4402BRIZ and SI8642ED-B-IS, the MAX14936AAWE+T uniquely combines 150Mbps speed, 5kVRMS VDE-certified isolation, dual 1.71V–5.5V supply support, and factory-configured default-low outputs - making it optimal for high-reliability, high-speed, fail-safe isolation in battery and medical systems.

FAQ
What is the maximum data rate supported by the MAX14936AAWE+T?
The MAX14936AAWE+T supports a maximum data rate of 150Mbps, verified across its full operating temperature range (–40°C to +125°C) and supply voltage range (1.71V–5.5V per side). This performance is enabled by its optimized capacitive isolation architecture and low-skew internal routing, making it suitable for high-speed SPI, fast GPIO, and digital sensor interfaces where timing integrity is critical.
Does the MAX14936AAWE+T require external pull-up or pull-down resistors on its enable pins?
No, the MAX14936AAWE+T includes internal 2µA pull-up resistors on both ENA and ENB pins, ensuring a defined high-enable state during power-up or floating conditions. This eliminates the need for external components and simplifies PCB layout, especially in space-constrained industrial and medical modules where reliability and BOM reduction are priorities.
How does the default-low output configuration of the MAX14936AAWE+T improve system safety?
The MAX14936AAWE+T's factory-configured default-low output state ensures that all OUTB1–OUTB4 pins drive low when their respective INA inputs are unpowered or ENB is deasserted. This fail-safe behavior prevents unintended activation of downstream field-side loads (e.g., relays, gate drivers) during power sequencing, brownouts, or controller resets - a critical requirement in battery management and industrial control systems.
What safety certifications apply to the MAX14936AAWE+T?
The MAX14936AAWE+T is certified to UL 1577 (5000VRMS), CSA C22.2 No. 5A (cUL), VDE 0884-11:2017 (Basic Insulation), and IEC 61010-1 / IEC 60601-1 for medical applications. These certifications validate its 848VRMS working voltage, 1200VP repetitive peak isolation, and 10kV surge immunity per IEC 61000-4-5 - confirming suitability for safety-critical industrial and patient-connected equipment.
Can the MAX14936AAWE+T operate with different supply voltages on Side A and Side B?
Yes, the MAX14936AAWE+T supports independent 1.71V–5.5V supplies on VDDA (Side A) and VDDB (Side B), enabling seamless level translation between disparate logic families - for example, interfacing a 1.8V FPGA core with a 5V RS-485 transceiver. This eliminates external level shifters and reduces power domain complexity in multivoltage systems.
