Product details
Overview
MAX14932EASE+ 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 default-low output configuration, 6.67ns minimum pulse width, and operates across –40°C to +125°C ambient for industrial fieldbus and battery management systems.
For engineers reviewing the MAX14932EASE+ datasheet, MAX14932EASE+ pinout, MAX14932EASE+ application, or MAX14932EASE+ equivalent, this device supports high-speed SPI/RS-485 isolation, level translation between mixed-voltage domains, and robust noise immunity in safety-critical power electronics and medical equipment.
Technical Context
The MAX14932EASE+ implements capacitive isolation using Analog Devices' proprietary silicon-dioxide barrier technology, enabling signal transfer across isolated power domains without magnetic coupling or optoelectronic components. Its architecture supports four independent unidirectional channels-two A→B and two B→A-with separate enable controls (ENA/ENB) and guaranteed propagation delay skew ≤1.6ns (same-direction) at 5V supply.
It delivers 25kV/µs common-mode transient immunity (CMTI), withstands ±10kV surge per IEC 61000-4-5, and meets VDE 0884-11 Basic Insulation requirements with 630VPK repetitive peak voltage rating. The device is certified to UL1577 (3750VRMS), cUL, TUV, and IEC 60601-1 for medical applications.

FAQ
What is the maximum data rate supported by MAX14932EASE+?
The MAX14932EASE+ supports a maximum data rate of 150Mbps, verified across all supply voltages (1.71V–5.5V) and temperature ranges (–40°C to +125°C). This enables high-speed isolated SPI, RS-422, and digital I/O applications where timing precision is critical - such as real-time motor control and battery cell monitoring. The device maintains <1ns pulse-width distortion even at full speed.
Does MAX14932EASE+ have a default output state, and what is it?
Yes, MAX14932EASE+ has a default-low output configuration. When either side's input is unpowered (e.g., VDDA or VDDB absent), the corresponding outputs (OUTA1/OUTA2 or OUTB1/OUTB2) drive low. This fail-safe behavior is critical for safety-critical systems like EV battery disconnect circuits and medical isolation barriers where undefined states must be avoided.
What safety certifications does MAX14932EASE+ hold?
MAX14932EASE+ is certified to UL1577 (3750VRMS), cUL (CSA 5A), VDE 0884-11:2017 (Basic Insulation), TUV, and IEC 60601-1 (medical). It meets 443VRMS working voltage, 630VPK repetitive peak, and withstands ±10kV surge per IEC 61000-4-5 - making it suitable for industrial, automotive, and Class II medical applications requiring regulatory compliance.
Can MAX14932EASE+ be used for level translation between different logic voltages?
Yes, MAX14932EASE+ supports independent 1.71V–5.5V supplies on each side (VDDA/GNDA and VDDB/GNDB), enabling seamless level translation - for example, interfacing a 1.8V FPGA I/O bank with a 5V microcontroller UART without external translators. Input thresholds scale with respective VDD, and outputs swing rail-to-rail relative to their local supply.
What is the common-mode transient immunity (CMTI) of MAX14932EASE+?
MAX14932EASE+ delivers 25kV/µs common-mode transient immunity (CMTI), measured per JEDEC JESD85. This high immunity prevents data corruption during fast voltage transients - such as those generated by IGBT switching in motor drives or DC-DC converter noise - ensuring reliable communication across the isolation barrier even in electrically noisy industrial environments.
