Product details
Overview
MAX14932CAWE+ 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 for industrial fieldbus and battery management systems.
For engineers reviewing the MAX14932CAWE+ datasheet, MAX14932CAWE+ pinout, MAX14932CAWE+ application, or MAX14932CAWE+ equivalent, this device supports high-speed SPI/RS-485 isolation with low propagation delay skew (≤1.6ns channel-to-channel), robust CMTI (25kV/µs), and safety-certified insulation up to 4600VPK transient voltage.
Technical Context
The MAX14932CAWE+ implements capacitive isolation with proprietary silicon-dioxide barrier technology, enabling bidirectional signal transfer across isolated domains without magnetic coupling. Its architecture supports four independent unidirectional channels - two A→B and two B→A - with separate enable inputs (ENA/ENB) for output control and three-state capability.
It delivers deterministic timing performance: propagation delay ≤14.9ns (max), pulse-width distortion ≤1ns, and rise/fall times ≤2ns at all supply voltages. The device meets VDE 0884-11 Basic Insulation requirements and supports level translation between disparate logic families via asymmetric supply rails.

FAQ
What is the maximum data rate supported by MAX14932CAWE+?
The MAX14932CAWE+ 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 serial interfaces such as SPI clock lines and real-time sensor data links without timing violations.
Does MAX14932CAWE+ support level translation between different logic families?
Yes, MAX14932CAWE+ supports true level translation: VDDA and VDDB operate independently from 1.71V to 5.5V, allowing direct connection to 1.8V FPGAs on one side and 5V microcontrollers on the other. Input thresholds scale with respective supply rails, eliminating external level shifters.
What safety certifications does MAX14932CAWE+ hold?
MAX14932CAWE+ is certified to UL1577 (3750VRMS), cUL (CSA 5A), VDE 0884-11:2017 (Basic Insulation), and TUV IEC 61010-1/60601-1. It achieves 443VRMS working voltage and 4600VPK transient isolation - meeting reinforced insulation requirements for industrial and medical systems.
What is the default output state of MAX14932CAWE+?
MAX14932CAWE+ has a default-low output configuration: when ENA or ENB is deasserted (low), the corresponding outputs (OUTA1/OUTA2 or OUTB1/OUTB2) drive low rather than high-impedance or high. This fail-safe behavior prevents unintended activation in power-loss scenarios.
How does MAX14932CAWE+ handle common-mode transients?
MAX14932CAWE+ achieves 25kV/µs common-mode transient immunity (CMTI), measured per VDE 0884-11. Its capacitive isolation barrier and internal filtering reject fast-rising noise on GNDA–GNDB paths - ensuring error-free operation in motor drives and switch-mode power supplies.
