Product details
Overview
MAX14936EAWE+ from Maxim Integrated is a four-channel, unidirectional 5kVRMS digital isolator with 150Mbps data rate, 1.71V–5.5V dual-supply operation, and default-low output configuration in a 16-pin wide SOIC package. It isolates SPI, RS-485, and industrial I/O signals between circuits with separate power domains up to +125°C ambient.
For engineers reviewing the MAX14936EAWE+ datasheet, MAX14936EAWE+ pinout, MAX14936EAWE+ application, or MAX14936EAWE+ equivalent, this device delivers high-speed galvanic isolation for fieldbus interfaces, battery management systems, and medical equipment requiring robust CMTI (25kV/µs) and safety-certified insulation.
Technical Context
The MAX14936EAWE+ implements capacitive isolation with proprietary silicon-dioxide barrier technology, supporting asymmetric 1.71V–5.5V supply rails on each side for level translation. Its channel architecture provides four A-to-B unidirectional signal paths (INA1→OUTB1, INA2→OUTB2, INA3→OUTB3, INA4→OUTB4), with independent enable controls (ENA/ENB) and default-low outputs when inputs are unpowered.
It achieves 150Mbps maximum data rate with sub-8ns typical propagation delay (tPLH/tPHL), <1ps pulse-width distortion at 5V, and guaranteed operation across –40°C to +125°C. Safety compliance includes UL1577 (5kVRMS/60s), VDE 0884-11 Basic Insulation, and IEC 61000-4-5 ±10kV surge immunity.

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, default-high outputs, 16-pin SOIC | Limited to 2.5kVRMS isolation - unsuitable for 5kVRMS safety-critical designs | Select when lower isolation rating suffices and default-high behavior aligns with system reset logic |
| SI8642ED-B-IS | 4-channel, 150Mbps, 5kVRMS, default-high outputs, 16-pin SOIC | Same speed/isolation but opposite default state - requires logic inversion or firmware adaptation | Choose if existing board layout supports same footprint and system design accommodates active-high default |
Compared with ADUM4402BRIZ and SI8642ED-B-IS, the MAX14936EAWE+ uniquely combines 150Mbps speed, 5kVRMS certification, and default-low outputs in a single wide-SOIC package - eliminating need for external pull-downs or level-shifting in fail-safe industrial and medical interfaces.

FAQ
What is the maximum data rate supported by the MAX14936EAWE+?
The MAX14936EAWE+ 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 to 5.5V). This enables high-speed isolation of SPI, RS-485, and other digital interfaces without introducing timing bottlenecks in the signal path.
Does the MAX14936EAWE+ require external pull-up or pull-down resistors on its input or output pins?
No, the MAX14936EAWE+ does not require external pull-up or pull-down resistors. Its ENA and ENB pins feature internal 2µA pullups to their respective supplies (VDDA/VDDB), and outputs default to low when inputs are unpowered - eliminating need for external biasing components in most configurations.
How does the MAX14936EAWE+ achieve 5kVRMS isolation certification?
The MAX14936EAWE+ achieves 5kVRMS isolation via a proprietary capacitive silicon-dioxide barrier fabricated using Maxim's process technology. It is certified to UL1577 (File E351759), VDE 0884-11 Basic Insulation, and IEC 61000-4-5 ±10kV surge, with 8mm creepage and clearance in its wide SOIC package.
Can the MAX14936EAWE+ operate with different supply voltages on each side?
Yes, the MAX14936EAWE+ supports independent 1.71V to 5.5V supplies on Side A (VDDA/GNDA) and Side B (VDDB/GNDB). This allows seamless level translation - for example, interfacing a 1.8V FPGA I/O bank with a 5V RS-485 transceiver without external level shifters.
What is the common-mode transient immunity (CMTI) specification for the MAX14936EAWE+?
The MAX14936EAWE+ has a minimum CMTI rating of 25kV/µs, measured per IEC 60747-5-5 with transient generator applied between GNDA and GNDB. This ensures reliable operation in high-noise environments such as motor drives, inverters, and industrial power supplies where rapid ground potential shifts occur.
