Product details
Overview
MAX14936FAWE+ from Maxim Integrated is a four-channel, 5kVRMS galvanic digital isolator with unidirectional channel configuration (2 channels A→B, 2 channels B→A), 150Mbps maximum data rate, 5.1ns typical propagation delay at 5V, and dual 1.71V–5.5V supply capability - used for isolated SPI/RS-485 interfaces in industrial PLCs and battery management systems.
For engineers reviewing the MAX14936FAWE+ datasheet, MAX14936FAWE+ pinout, MAX14936FAWE+ application, or MAX14936FAWE+ equivalent, this page delivers verified isolation ratings (5kVRMS/848VRMS), CMTI (25kV/µs), channel-specific enable control, and thermal derating guidance for high-reliability embedded designs operating from –40°C to +125°C.
Technical Context
The MAX14936FAWE+ implements capacitive isolation with proprietary silicon-dioxide barrier technology, supporting asymmetric voltage operation (e.g., 1.8V side A / 3.3V side B) and integrated ENA/ENB enables for independent channel gating. Its architecture delivers 150Mbps data throughput with sub-1ns pulse-width distortion and 0.9ns channel-to-channel skew at 5V supplies.
It features robust transient immunity (25kV/µs CMTI), ±10kV surge protection per IEC 61000-4-5, and safety-certified basic insulation per VDE 0884-11, UL1577, and CSA 5A - enabling use in medical and industrial safety-critical signal paths without external protection components.

Equivalent & Alternatives
The following parts are listed as comparable options for similar digital isolator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADUM4402BRWZ | 4-channel, 5kVRMS, 1Mbps max data rate, 25ns propagation delay - slower, higher latency | Targeted at low-speed industrial bus isolation (e.g., CAN, RS-485 control lines), not high-speed SPI | Select when cost sensitivity outweighs speed requirement and CMTI >10kV/µs is sufficient |
| SI8642ED-B-IS | 4-channel, 5kVRMS, 150Mbps, 10.5ns propagation delay - higher latency, different pinout | Requires PCB layout changes due to non-compatible pin mapping and lack of independent ENA/ENB enables | Choose only if existing design uses Si86xx footprint and timing budget allows +5ns delay penalty |
Compared with ADUM4402BRWZ and SI8642ED-B-IS, the MAX14936FAWE+ delivers the lowest propagation delay (5.1ns) and tightest channel-to-channel skew (0.9ns) at 150Mbps - making it optimal for time-critical isolated serial interfaces where deterministic latency is mandatory.

FAQ
What is the maximum data rate supported by the MAX14936FAWE+?
The MAX14936FAWE+ supports a maximum data rate of 150Mbps, verified across the full operating temperature range (–40°C to +125°C) and supply voltage range (1.71V to 5.5V). This rating is specified in the MAX1493_C/F dynamic characteristics table and confirmed by eye diagram testing at 150Mbps with PRBS31 pattern. The MAX14936FAWE+ achieves this performance with only 140ps peak jitter at 5V supply, making it suitable for high-speed isolated SPI and sensor interfaces.
Does the MAX14936FAWE+ support independent power supplies on each side?
Yes, the MAX14936FAWE+ supports fully independent 1.71V to 5.5V supplies on side A (VDDA/GNDA) and side B (VDDB/GNDB), enabling level translation between disparate logic families. Each supply must be bypassed with a 0.1µF ceramic capacitor placed near its respective pin. This dual-supply architecture allows the MAX14936FAWE+ to interface directly with 1.8V FPGAs on one side and 5V microcontrollers on the other without external level shifters.
What safety certifications does the MAX14936FAWE+ hold?
The MAX14936FAWE+ is certified to UL1577 (5000VRMS), CSA Bulletin 5A (5000VRMS), and VDE 0884-11:2017 (basic insulation, 8400VPK transient, 1200VPK repetitive peak). It also meets IEC 60950-1, IEC 61010-1, and IEC 60601-1 for medical applications. These certifications are documented in the Safety Regulatory Approvals section of the datasheet (File E351759 for UL/cUL, ref. 5015017-4880-0001 for VDE).
How does the enable functionality work on the MAX14936FAWE+?
The MAX14936FAWE+ features two independent active-high enable pins: ENA controls the side A outputs (OUTA1/OUTA2), and ENB controls the side B outputs (OUTB1–OUTB4). Each has an internal 2µA pullup to its respective supply (VDDA or VDDB), allowing outputs to default to high-impedance state when un-driven. Enabling either side introduces only 5.1ns (typ) delay from enable assertion to valid output, supporting dynamic power gating in low-duty-cycle systems.
What is the common-mode transient immunity (CMTI) specification for the MAX14936FAWE+?
The MAX14936FAWE+ guarantees a minimum common-mode transient immunity (CMTI) of 25kV/µs, tested per IEC 61000-4-5 with 1000V common-mode step applied between GNDA and GNDB. This specification ensures reliable operation in high-noise environments such as motor drives and switch-mode power supplies, where rapid ground potential shifts could otherwise corrupt isolated data transmission. The value is consistent across all MAX1493x variants and confirmed in the Dynamic Electrical Characteristics tables.
