Product details
Overview
MAX14930CASE+ 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. It features 6.67ns minimum pulse width, <1ns pulse-width distortion at 5V, and operates across –40°C to +125°C for industrial fieldbus and isolated SPI/RS-485 interfaces.
For engineers reviewing the MAX14930CASE+ datasheet, MAX14930CASE+ pinout, MAX14930CASE+ application, or MAX14930CASE+ equivalent, this page delivers verified electrical specs, safety-certified isolation ratings (UL, VDE, cUL), package dimensions, channel configuration details, and real-world design guidance for high-noise industrial signal integrity.
Technical Context
The MAX14930CASE+ implements capacitive isolation with proprietary silicon-dioxide dielectric barriers, supporting asymmetric supply voltages (e.g., 1.8V side A / 3.3V side B) and enabling level translation. Its architecture includes integrated enable inputs (ENA/ENB) per side for three-state output control and supports default-low output state when input is unpowered.
It belongs to the MAX1493x family optimized for high CMTI (25kV/µs), low propagation delay skew (<1.6ns channel-to-channel same-direction), and robust surge immunity (±10kV per IEC 61000-4-5). The device is rated for continuous 443VRMS working voltage and 630VPK repetitive peak isolation per VDE 0884-11.
Key Specifications

| Isolation Rating | 2.75kVRMS withstand (60s), 443VRMS continuous working voltage - meets basic insulation requirements for industrial safety standards |
| Max Data Rate | 150Mbps - enables high-speed serial links such as isolated USB bridge control or fast SPI in motor drives |
| Propagation Delay | 4.9–14.9ns (tPHL/tPLH, voltage-dependent) - ensures tight timing budgets in real-time control loops |
| CMTI | 25kV/µs - rejects fast common-mode transients in variable-frequency drives and power converters |
| Supply Range | 1.71V to 5.5V per side - allows direct interfacing with 1.8V FPGAs and 5V microcontrollers without level shifters |

Equivalent & Alternatives
The following parts are listed as comparable options for similar digital isolator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ISO6741QDWR | 4-channel, 5000VRMS, 50Mbps max data rate, 16-pin SOIC - lower speed but higher isolation rating | Suitable for medical mains-connected equipment requiring reinforced insulation, not high-speed industrial comms | Select when 5kVRMS isolation is mandatory and data rate ≤50Mbps suffices |
| ADUM140D0BRIZ | 4-channel, 3750VRMS, 150Mbps, 16-pin SOIC - similar speed but uses iCoupler magnetic isolation | Preferred where magnetic immunity is critical (e.g., near transformers), but higher CMTI not required | Choose for legacy ADI iCoupler ecosystem compatibility and magnetic-field resilience |
Compared with ISO6741QDWR and ADUM140D0BRIZ, the MAX14930CASE+ uniquely combines 2.75kVRMS isolation, 150Mbps speed, and 25kV/µs CMTI in a single wide-SOIC package - making it optimal for high-noise, high-data-rate industrial interfaces where both speed and transient rejection are non-negotiable.

FAQ
What is the maximum data rate supported by the MAX14930CASE+?
The MAX14930CASE+ supports a maximum data rate of 150Mbps under specified conditions (VDDA/VDDB ≥ 4.5V, CL = 15pF). This is confirmed in the Dynamic Electrical Characteristics table for MAX1493_B/E variants. At lower supply voltages (e.g., 1.8V), the achievable rate remains high but may require validation against timing margins in the target system. The MAX14930CASE+ part number corresponds to the 150Mbps variant with default-low output configuration in wide-body SOIC.
Does the MAX14930CASE+ support independent supply voltages on each side?
Yes, the MAX14930CASE+ supports fully independent 1.71V to 5.5V supplies on side A (VDDA/GNDA) and side B (VDDB/GNDB). This enables true level translation - for example, interfacing a 1.8V FPGA I/O bank with a 3.3V microcontroller bus without external level shifters. The DC Electrical Characteristics table explicitly defines VIH/VIL thresholds relative to their respective supply rails.
What safety certifications does the MAX14930CASE+ hold?
The MAX14930CASE+ is certified to UL 1577 (3750VRMS), CSA C22.2 No. 5A (cUL), and VDE 0884-11:2017 (Basic Insulation, 4600VPK transient, 630VPK repetitive peak). These are documented in the Safety Regulatory Approvals section and confirmed via file references E351759 and 5015017-4880-0001/272147/TL7/SCT. It also meets IEC 61000-4-5 surge (±10kV) and IEC 60601-1 for medical MOOP.
What is the default output state of the MAX14930CASE+ when inputs are unpowered?
The MAX14930CASE+ is configured as a default-low device: when an input is unpowered (e.g., INA1 floating or at 0V), the corresponding output (OUTB1) transitions to a logic-low state. This behavior is defined in the General Description and confirmed by the "default low configuration" suffix in the Ordering Information. It prevents undefined states during power sequencing in industrial control systems.
How does the MAX14930CASE+ handle common-mode transients?
The MAX14930CASE+ achieves 25kV/µs common-mode transient immunity (CMTI), measured per IEC 60747-5-5 with 1000V common-mode step applied between GNDA and GNDB. This is enabled by its capacitive isolation architecture and internal noise suppression circuitry. The value is guaranteed across –40°C to +125°C and is critical for reliable operation in motor drives and inverters where fast dv/dt events occur.
