Product details
Overview
MAX14936BAWE+T from Maxim Integrated is a four-channel, 5kVRMS galvanic digital isolator with unidirectional channel configuration (2A→B, 2B→A), 150Mbps maximum data rate, 5.1ns typical propagation delay (tPLH), and dual 1.71V–5.5V supply capability. It operates from –40°C to +125°C and is used in isolated SPI interfaces and industrial fieldbus nodes requiring high-speed, robust isolation.
For engineers reviewing the MAX14936BAWE+T datasheet, MAX14936BAWE+T pinout, MAX14936BAWE+T application, or MAX14936BAWE+T equivalent, this page delivers verified electrical specs, functional pin mapping, safety-rated insulation parameters, real-world use cases for battery management and medical systems, and two validated alternative parts with precise technical distinctions.
Technical Context
The MAX14936BAWE+T implements capacitive isolation using Maxim's proprietary silicon-dioxide barrier technology, supporting asymmetric voltage operation (e.g., 1.8V on Side A, 3.3V on Side B) and enabling level translation. Its architecture features independent enable inputs (ENA/ENB) per side and supports high CMTI of 25kV/µs to reject fast common-mode transients in noisy industrial environments.
This variant belongs to the MAX14936 subfamily - characterized by 150Mbps data rate, low pulse-width distortion (<1ns), and optimized timing skew (tSCSLH ≤ 1.6ns). It is not bidirectional; I²C applications require the MAX14937, and 2.75kVRMS-rated designs should use the MAX14930–MAX14932 series.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Isolation Rating | 5000VRMS withstand for 60s (VISO); continuous 848VRMS working voltage (VIOWM) |

Equivalent & Alternatives
The following parts are listed as comparable options for similar digital isolator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Si8642ED-B-IS | 4-channel, 25Mbps max rate, 2.5kVRMS isolation, 16-pin SOIC, 2.5–5.5V supply | Limited to lower-speed industrial I/O; lacks 150Mbps and 5kVRMS rating required for EV BMS or high-end servo drives | Select when cost sensitivity outweighs speed/safety needs and 2.5kVRMS suffices for end-equipment certification |
| ADUM4402BRWZ | 4-channel, 10Mbps max rate, 5kVRMS, 16-pin SOIC, 2.7–5.5V supply, no side-specific enable pins | Lower data rate restricts use to legacy fieldbus; missing ENA/ENB limits dynamic power gating in battery-powered systems | Choose only if legacy design reuse is mandatory and 150Mbps performance is unnecessary |
Compared with Si8642ED-B-IS and ADUM4402BRWZ, the MAX14936BAWE+T uniquely delivers 150Mbps speed within a 5kVRMS-rated wide-body SOIC package, enabling next-generation isolated interfaces where timing integrity, surge resilience, and mixed-voltage operation are non-negotiable.

FAQ
What is the maximum data rate supported by the MAX14936BAWE+T?
The MAX14936BAWE+T supports a maximum data rate of 150Mbps, verified across all supply voltages (1.71V–5.5V) and temperatures (–40°C to +125°C). This is confirmed in the Dynamic Electrical Characteristics table for MAX1493_C/F variants, with minimum pulse width of 6.67ns and peak eye diagram jitter of 160ps at 1.8V supplies.
Does the MAX14936BAWE+T support bidirectional communication?
No, the MAX14936BAWE+T is unidirectional: two channels transmit from Side A to Side B (INA1→OUTB1, INA2→OUTB2), and two channels transmit from Side B to Side A (INB1→OUTA1, INB2→OUTA2). For true bidirectional protocols like I²C, Maxim specifies the MAX14937 as the appropriate alternative.
What safety certifications does the MAX14936BAWE+T hold?
The MAX14936BAWE+T is certified to UL 1577 (5000VRMS), cUL (CSA 5A), VDE 0884-11 Basic Insulation (8400VPK transient, 1200VP repetitive peak), and meets IEC 61000-4-5 ±10kV surge. These are documented in the Safety Regulatory Approvals section and IEC Insulation Testing tables.
Can the MAX14936BAWE+T operate with different supply voltages on each side?
Yes - the MAX14936BAWE+T accepts independent 1.71V–5.5V supplies on Side A (VDDA) and Side B (VDDB), enabling seamless level translation (e.g., 1.8V FPGA ↔ 5V sensor interface). This is explicitly stated in the General Description and DC Electrical Characteristics sections.
What is the propagation delay skew between channels on the MAX14936BAWE+T?
For same-direction channels (e.g., INA1→OUTB1 vs. INA2→OUTB2), the MAX14936BAWE+T exhibits channel-to-channel skew (tSCSLH) of ≤1.6ns over temperature and voltage. This low skew is critical for parallel data bus isolation and is specified in the Dynamic Electrical Characteristics (MAX1493_C/F) table.
