Product details
Overview
MAX14932FAWE+ from Analog Devices is a 4-channel, unidirectional digital isolator with 2.75kVRMS galvanic isolation, 150Mbps maximum data rate, and independent 1.71V–5.5V dual-supply operation across isolated domains. It features default-low output configuration, 6.67ns minimum pulse width, and operates from –40°C to +125°C - enabling robust signal isolation in high-noise industrial fieldbus and battery management systems.
For engineers reviewing the MAX14932FAWE+ datasheet, MAX14932FAWE+ pinout, MAX14932FAWE+ application, or MAX14932FAWE+ equivalent, this device delivers precise timing integrity (±1ps pulse-width distortion at 5V), ultra-high CMTI (25kV/µs), and seamless level translation between mixed-voltage microcontrollers and isolated peripherals without external logic.
Technical Context
The MAX14932FAWE+ implements capacitive isolation with proprietary silicon-dioxide barrier technology, supporting only unidirectional channel flow (A→B) across all four channels. Its architecture includes integrated enable inputs (ENA/ENB) for three-state control and supports simultaneous high-speed operation on both sides with independent supply rails.
It belongs to the MAX1493x family optimized for 2.75kVRMS isolation rating and 150Mbps performance, distinct from lower-isolation (1kVRMS) MAX1413x or bidirectional MAX14933 variants. The FAWE+ suffix confirms wide-body SOIC-16 package (10.3mm × 7.5mm) with 8mm creepage/clearance and RoHS-compliant lead finish.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Isolation Rating | 2.75kVRMS withstand (60s), 443VRMS continuous working voltage - meets UL1577, VDE 0884-11 Basic Insulation |
| Max Data Rate | 150Mbps - enables high-speed SPI clocking and real-time sensor data transfer across isolation barrier |
| Propagation Delay | 4.9–14.9ns (tPHL/tPLH, voltage-dependent) - ensures sub-15ns latency for time-critical control loops |
| Pulse-Width Distortion | ≤1ns (|tPLH − tPHL| at 4.5–5.5V) - preserves signal duty cycle integrity for PWM and clock distribution |
| CMTI | 25kV/µs - rejects fast common-mode transients in motor drives and power converters |
| Supply Range | 1.71V–5.5V per side - allows direct interfacing with 1.8V FPGAs and 5V legacy controllers |
| Operating Temp | –40°C to +125°C - qualified for under-hood automotive and industrial ambient environments |
Pinout & Package
MAX14932FAWE+ uses a 16-pin wide-body SOIC package (10.3mm × 7.5mm, outline 21-0042) with 8mm creepage and clearance, rated for 2.75kVRMS isolation. Pin functions are asymmetric: Side A (input side) and Side B (output side) are electrically isolated with dedicated supplies and grounds.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| INA1–INA4 | Side A digital inputs | Accept 1.71V–5.5V logic signals; VIH = 0.7×VDDA, VIL ≤ 0.8V |
| OUTB1–OUTB4 | Side B digital outputs | Drive 4mA loads; VOH = VDDB − 0.4V, VOL ≤ 0.4V |
| ENA | Side A output enable | Active-high; controls three-state behavior of OUTA1–OUTA4 (not used in MAX14932) |
| ENB | Side B output enable | Active-high; places OUTB1–OUTB4 in high-impedance state when low |
| VDDA / GNDA | Side A power/ground | Isolated 1.71V–5.5V supply domain for input-side circuitry |
| VDDB / GNDB | Side B power/ground | Isolated 1.71V–5.5V supply domain for output-side circuitry |
Key Features
| Feature | Design Value |
|---|---|
| Capacitive isolation barrier | SiO₂ dielectric enables 2.75kVRMS rating with <2pF inter-side capacitance - minimizes noise coupling |
| Ultra-low propagation skew | ≤0.9ns channel-to-channel (same direction) - critical for synchronized multi-signal isolation (e.g., SPI bus) |
| High-speed enable control | tEN = 5.1ns (4.5–5.5V), tTRI = 2.7ns - supports dynamic channel gating in real-time systems |
| Robust ESD protection | ±4kV HBM on all pins - eliminates need for external TVS in most industrial I/O designs |
| Low-power at speed | 18.6mA total (10.5mA Side A + 8.1mA Side B) at 50MHz/5V - reduces thermal load in dense PCB layouts |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar digital isolator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX14932BAWE+ | Same 2.75kVRMS isolation and 150Mbps rating, but default-high output state instead of default-low | Requires logic inversion in systems where output must be high during power-up or fault conditions | Select MAX14932BAWE+ only if default-high assertion is required for fail-safe signaling |
| ISO6741FDWR | Texas Instruments' 4-channel isolator with 5000VRMS rating, 50Mbps max data rate, and 3.0V–5.5V supply range | Lower speed limits use in high-bandwidth SPI; higher isolation suits mains-connected equipment | Choose ISO6741FDWR when >4kVRMS isolation is mandated, but accept ⅓ bandwidth reduction vs. MAX14932FAWE+ |
Compared with MAX14932BAWE+, the MAX14932FAWE+ provides identical timing and isolation specs but guarantees safe low-state outputs at power-on - critical for disabling actuators in industrial safety circuits. Against ISO6741FDWR, it trades 2.25kVRMS for 50% higher data rate and wider 1.71V–5.5V supply flexibility.

FAQ
What is the isolation voltage rating of the MAX14932FAWE+?
The MAX14932FAWE+ is rated for 2.75kVRMS withstand voltage (60 seconds), 443VRMS maximum continuous working voltage (VIOWM), and 630VPK repetitive peak voltage (VIORM). It is certified to UL1577, VDE 0884-11 (Basic Insulation), and IEC 61000-4-5 (±10kV surge), making it suitable for reinforced insulation in industrial and medical applications.
Does the MAX14932FAWE+ support bidirectional communication?
No, the MAX14932FAWE+ is strictly unidirectional - all four channels transmit signals from Side A (inputs INA1–INA4) to Side B (outputs OUTB1–OUTB4). For bidirectional protocols like I²C, Analog Devices specifies the MAX14933; using MAX14932FAWE+ in such applications requires external logic or separate forward/reverse isolator pairs.
What is the meaning of the 'F' in MAX14932FAWE+?
The 'F' in MAX14932FAWE+ denotes the default-low output configuration: when an input is unpowered or floating, the corresponding OUTBx output defaults to logic low. This differs from the 'B' variant (MAX14932BAWE+), which defaults high - a critical distinction for fail-safe system design in motor control or power gate drivers.
Can the MAX14932FAWE+ operate with mismatched supply voltages on each side?
Yes, the MAX14932FAWE+ supports independent 1.71V–5.5V supplies on Side A (VDDA/GNDA) and Side B (VDDB/GNDB), enabling true level translation - e.g., interfacing a 1.8V FPGA I/O bank to a 5V isolated ADC. Input thresholds scale with respective VDD, and output drive strength adapts to VDDB.
What package type does MAX14932FAWE+ use, and what are its mechanical dimensions?
The MAX14932FAWE+ uses a 16-pin wide-body SOIC package (outline 21-0042) measuring 10.3mm × 7.5mm with 2.65mm height. It provides 8mm creepage and clearance distances, satisfying reinforced insulation requirements for 300V RMS working voltage per IEC 60664-1.
