Product details
Overview
MAX14930CAWE+ from Analog Devices is a 4-channel, 2.75kVRMS digital isolator in a 16-pin wide-body SOIC package (10.3mm × 7.5mm), supporting unidirectional signal transfer between isolated power domains at up to +125°C ambient. It delivers 1Mbps data rate, 25kV/µs common-mode transient immunity, and operates with independent 1.71V–5.5V supplies on each side-enabling use in isolated SPI, RS-232, and industrial I/O interfaces.
For engineers reviewing the MAX14930CAWE+ datasheet, MAX14930CAWE+ pinout, MAX14930CAWE+ application, or MAX14930CAWE+ equivalent, this page provides verified isolation ratings, channel configuration details, thermal derating curves, safety certifications (UL, VDE, cUL), and design-critical timing parameters including propagation delay skew and pulse-width distortion.
Technical Context
The MAX14930CAWE+ implements capacitive galvanic isolation using Maxim's proprietary process, providing reinforced insulation with 2.75kVRMS withstand voltage for 60 seconds and 443VRMS continuous working voltage. Its four unidirectional channels are configured as A-side inputs → B-side outputs (INA1–INA4 → OUTB1–OUTB4), with separate enable pins (ENA/ENB) controlling output states.
It supports default-low output behavior when input is unpowered, features ±4kV HBM ESD protection, and meets IEC 61000-4-5 surge immunity (±10kV). The device is rated for -40°C to +125°C operation and qualified per DIN VDE V 0884-11:2017-01 for basic insulation with 630VPK repetitive peak voltage.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Isolation Rating | 2.75kVRMS for 60s (VISO); enables compliance with reinforced insulation requirements in industrial and medical systems |
| Data Rate | 1Mbps maximum; suitable for low-speed isolated control, status monitoring, and legacy serial interfaces |
| Common-Mode Transient Immunity | 25kV/µs minimum; ensures reliable operation in noisy motor drives and PLC backplanes |
| Supply Voltage Range | 1.71V to 5.5V per side; allows direct interfacing with 1.8V, 2.5V, 3.3V, and 5V logic without level shifters |
| Propagation Delay Skew | ≤6.7ns channel-to-channel (same direction); critical for synchronous multi-bit data capture in isolated ADC/DAC links |
| Operating Temperature | -40°C to +125°C ambient; validated for under-hood automotive and high-temp industrial environments |

Pinout & Package
Package: 16-pin wide-body SOIC (W16M+8), outline 21-0042, 8mm creepage and clearance, RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3, 4 (INA1–INA4) | A-side digital inputs | Accept 1.71V–5.5V logic; VIH = 0.7×VDDA, VIL ≤ 0.8V - compatible with CMOS and TTL |
| 5 (GNDA) | A-side ground reference | Return path for VDDA supply and input/output signals on side A; must be isolated from GNDB |
| 6 (VDDA) | A-side power supply | Supplies input circuitry and drivers for INAx; UVLO threshold 1.45–1.71V prevents erratic startup |
| 7, 8, 9, 10 (OUTB1–OUTB4) | B-side digital outputs | Push-pull outputs sinking/sourcing 4mA; VOH ≥ VDDA–0.4V, VOL ≤ 0.4V at 4mA load |
| 11 (GNDB) | B-side ground reference | Return path for VDDB supply and output signals on side B; galvanically isolated from GNDA |
| 12 (VDDB) | B-side power supply | Supplies output drivers for OUTBx; independent of VDDA - enables level translation across domains |
| 13 (ENB) | B-side output enable | Active-high; places OUTB1–OUTB4 in high-impedance state when low - supports bus sharing |
| 14 (ENA) | A-side input enable | Active-high; disables INA1–INA4 inputs when low - reduces dynamic power during idle |
| 15, 16 | No Connect | Internally unused; must remain floating or tied to GNDA/GNDB per layout guidelines |
Key Features
| Feature | Design Value |
|---|---|
| Reinforced Isolation Barrier | 2.75kVRMS withstand (60s), 443VRMS continuous working voltage - certified to UL1577, VDE 0884-11, and CSA 5A |
| Low-Power Operation | 1.2–1.9mA per side at 500kHz (1.8V–5V supplies); enables battery-powered isolated sensors |
| High Noise Immunity | 25kV/µs CMTI - maintains signal integrity in variable-frequency drives and switch-mode power supplies |
| Configurable Default State | Default-low output behavior ensures safe de-assertion of downstream actuators during power loss or reset |
| Wide Supply Flexibility | Independent 1.71V–5.5V rails on both sides - eliminates external level translators in mixed-voltage systems |

Equivalent & Alternatives
The following parts are listed as comparable options for similar digital isolator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADUM1400ARWZ | 1kVRMS isolation, 1Mbps, 16-pin wide SOIC, but only 10kV surge rating and no VDE 0884-11 certification | Suitable for non-safety-critical industrial controls where 2.75kVRMS is not mandated | Select MAX14930CAWE+ when regulatory compliance (UL/VDE) or higher surge immunity (±10kV) is required |
| SI8640ED-B-IS | 2.5kVRMS isolation, 1Mbps, 16-pin SOIC, but uses capacitive isolation with different CMTI (25kV/µs same), no default-low option | Applicable in cost-sensitive designs where default-state control is not needed | Choose MAX14930CAWE+ for guaranteed default-low behavior and full 2.75kVRMS certification stack |
Compared with ADUM1400ARWZ and SI8640ED-B-IS, the MAX14930CAWE+ uniquely combines 2.75kVRMS UL/VDE-certified isolation, ±10kV IEC 61000-4-5 surge tolerance, and factory-configured default-low outputs - making it the preferred choice for safety-critical industrial and medical isolation where fail-safe behavior and regulatory alignment are mandatory.

FAQ
What is the isolation voltage rating of the MAX14930CAWE+?
The MAX14930CAWE+ is rated for 2.75kVRMS withstand voltage for 60 seconds (VISO), 443VRMS continuous working voltage (VIOWM), and 630VPK repetitive peak voltage (VIORM). It is certified to UL1577, VDE 0884-11:2017-01, and CSA Bulletin 5A - meeting reinforced insulation requirements for industrial and medical applications.
Does the MAX14930CAWE+ support level translation between different logic voltages?
Yes, the MAX14930CAWE+ supports true bidirectional level translation: VDDA and VDDB operate independently from 1.71V to 5.5V, allowing signals to cross between 1.8V, 2.5V, 3.3V, and 5V domains without external components. Input thresholds scale with respective supplies (VIH = 0.7×VDD), and outputs swing rail-to-rail relative to their local VDD.
What is the default output state of the MAX14930CAWE+ when its inputs are unpowered?
The MAX14930CAWE+ is configured as a default-low device: when INA1–INA4 are unpowered or floating, OUTB1–OUTB4 drive low. This fail-safe behavior ensures downstream circuits (e.g., disable lines, enable gates) remain de-asserted during power sequencing or fault conditions - a key requirement in safety-critical systems.
How does the MAX14930CAWE+ handle high-noise environments like motor drives?
The MAX14930CAWE+ achieves 25kV/µs common-mode transient immunity (CMTI), validated per IEC 61000-4-5 with ±10kV surge pulses. Its capacitive isolation barrier and internal filtering reject fast transients induced by IGBT switching, ensuring reliable data transmission in VFDs, servo amplifiers, and power converters without bit errors or latch-up.
Is the MAX14930CAWE+ pin-compatible with other members of the MAX14930–MAX14932 family?
Yes, all MAX14930–MAX14932 variants share identical 16-pin wide SOIC pinouts and footprint (W16M+8, outline 21-0042). The MAX14930CAWE+ differs only in data rate (1Mbps) and default output state (low); swapping in a MAX14931CAWE+ (25Mbps) or MAX14932CAWE+ (150Mbps) requires no PCB changes but may need timing validation in high-speed layouts.
