Product details
Overview
MAX14936BAWE+ from Maxim Integrated is a four-channel, unidirectional 5kVRMS digital isolator with 150Mbps data rate, 1.71V–5.5V dual-supply operation per side, and default-low output configuration. It provides galvanic isolation between microcontroller and field-side interfaces in industrial I/O modules and battery management systems.
For engineers reviewing the MAX14936BAWE+ datasheet, MAX14936BAWE+ pinout, MAX14936BAWE+ application, or MAX14936BAWE+ equivalent, key selection criteria include its 150Mbps maximum data rate, 5kVRMS isolation rating, 16-pin wide SOIC package, and channel direction (A→B only) with ENA/ENB enable control.
Technical Context
The MAX14936BAWE+ implements capacitive isolation with proprietary silicon-dioxide barrier technology, supporting asymmetric 1.71V–5.5V supplies on each side for level translation. Its four channels are configured as A-side inputs (INA1–INA4) driving B-side outputs (OUTB1–OUTB4), with independent active-high enables (ENA, ENB).
It delivers 150Mbps operation at ≤14ps pulse-width distortion and ≤7.9ns propagation delay skew (opposing direction), with 25kV/µs common-mode transient immunity. The device meets VDE 0884-11 Basic Insulation and UL1577 safety standards for reinforced isolation up to 5000VRMS.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Isolation Rating | 5000VRMS withstand for 60s - ensures long-term reliability in high-noise industrial environments |
| Max Data Rate | 150Mbps - supports high-speed SPI, fast serial I/O, and real-time sensor feedback loops |
| Supply Voltage Range | 1.71V to 5.5V per side - enables direct interfacing with 1.8V FPGAs and 5V PLC logic without level shifters |
| Propagation Delay | 4.9ns to 14.9ns (tPHL, VDD=1.8V–5.5V) - guarantees sub-15ns timing margin for 100MHz clock domains |
| CMTI | 25kV/µs - prevents false triggering during fast transients in motor drives and HV inverters |
| Operating Temp | −40°C to +125°C - qualified for under-hood automotive and industrial control cabinet deployment |

Pinout & Package
Package: 16-pin wide-body SOIC (W16M+8), 10.3mm × 7.5mm, 8mm creepage/clearance, RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 16 | VDDA / VDDB | Independent power supplies for isolated sides - requires local 0.1µF ceramic bypassing |
| 2, 8, 9, 15 | GNDA / GNDB | Dedicated ground references per side - must not be shorted across isolation barrier |
| 3–6 | INA1–INA4 | A-side digital inputs - drive OUTB1–OUTB4; accept 0.7×VDDA logic thresholds |
| 10, 7 | ENB / ENA | Active-high enables - internal 2µA pull-up; disable outputs to high-impedance state |
| 11–14 | OUTB1–OUTB4 | B-side CMOS outputs - default-low when input unpowered; sink/source 4mA |
| - | I.C. | Internally connected - leave unconnected or tie to GNDA/VDDA (no functional impact) |

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, 16-pin SOIC, default-high outputs | Limited to lower-voltage industrial use; lacks 5kVRMS rating for mains-referenced systems | Select when cost sensitivity outweighs need for 5kVRMS or 150Mbps performance |
| SI8642ED-B-IS | 4-channel, 150Mbps, 5kVRMS, 16-pin SOIC, default-low, but uses capacitive isolation with different CMTI (35kV/µs) | Higher CMTI suits ultra-noisy motor control; slightly higher supply current at 150Mbps | Prefer for extreme EMI environments where >25kV/µs immunity is critical |
Compared with ADUM4402BRIZ and SI8642ED-B-IS, the MAX14936BAWE+ uniquely combines 150Mbps speed, 5kVRMS isolation, default-low outputs, and guaranteed −40°C to +125°C operation - making it optimal for high-reliability industrial and automotive subsystems requiring both speed and safety.

FAQ
What is the maximum data rate supported by the MAX14936BAWE+?
The MAX14936BAWE+ 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 per side). This is confirmed in the Dynamic Electrical Characteristics table for MAX1493_C/F variant in the official datasheet, with minimum pulse width of 6.67ns and propagation delay as low as 4.9ns.
Does the MAX14936BAWE+ support bidirectional communication?
No, the MAX14936BAWE+ is strictly unidirectional: signals flow from Side A inputs (INA1–INA4) to Side B outputs (OUTB1–OUTB4). For bidirectional applications like I²C, Maxim specifies the MAX14937 - the MAX14936BAWE+ does not implement any reverse-path channels or open-drain logic required for bidirectional protocols.
What is the default output state of the MAX14936BAWE+ when inputs are unpowered?
The MAX14936BAWE+ has a default-low output configuration, meaning all OUTB1–OUTB4 pins drive low when their corresponding INA1–INA4 inputs are unpowered or floating. This behavior is defined by the "B" suffix in the part number and is confirmed in the Product Selector Guide and Ordering Information section of the datasheet.
Which safety certifications apply to the MAX14936BAWE+?
The MAX14936BAWE+ is certified to UL 1577 (5000VRMS), cUL (CSA 5A), VDE 0884-11 Basic Insulation (8400VPK transient, 1200VP repetitive peak), and IEC 61010-1/60601-1 for medical use. These are explicitly listed in the Safety Regulatory Approvals section and validated via file numbers E351759 and 5015017-4880-0001/272147/TL7/SCT.
Can the MAX14936BAWE+ operate with mismatched supply voltages on Side A and Side B?
Yes, the MAX14936BAWE+ supports independent 1.71V–5.5V supplies on VDDA and VDDB - enabling true level translation. For example, VDDA can be 1.8V (for an FPGA I/O bank) while VDDB is 5V (for legacy field-side logic), with no external components required. This is specified in the DC Electrical Characteristics table and General Description.
