MAX14932CAWE+

Digital Isolators Overview

The MAX14932CAWE+ is a four-channel digital isolator utilizing capacitive coupling technology, housed in a 16-lead SOIC-Wide package. It supports a data rate of 150 Mbps with a typical common-mode transient immunity of 25 kV/µs. The device operates on a supply voltage range of 1.71 V to 5.5 V and features a 2/2 channel configuration. It provides an isolation voltage of 2750 Vrms and functions within a temperature range of -40°C to +125°C.

Digital Isolators Feature Summary

• Provides high-speed signal transmission at 150 Mbps using capacitive coupling for robust noise immunity.
• Features a 2/2 channel configuration allowing independent control of input-to-output directionality.
• Delivers strong common-mode transient immunity of 25 kV/µs to maintain signal integrity in noisy environments.

Digital Isolators Applications

• Industrial automation systems requiring galvanic isolation
• Programmable logic controllers (PLCs)
• Inverter motor drives
• Power metering equipment

Digital Isolators Procurement Notes

Verify the specific suffix 'C' indicates the 150 Mbps speed grade, distinct from other variants like 'A' or 'E'. Confirm the '+T' tape-and-reel option if required, as the base part number typically denotes tube packaging. Ensure the 16-SOIC footprint matches the target PCB design constraints.

Digital Isolators Selection Notes

Select this component when a balance between moderate speed and high reliability is needed. The 150 Mbps rate suits most industrial protocols, while the wide supply range accommodates various logic levels. The 2/2 configuration offers flexibility for bidirectional or mixed-directional signal paths compared to fixed unidirectional options.

Digital Isolators Part Context

This device belongs to the MAX1493x family of general-purpose digital isolators. It shares the same physical package and basic isolation architecture with higher-speed variants like the MAX14931 but offers lower bandwidth. It serves as a cost-effective solution for applications where extreme speed is unnecessary but safety certification and noise immunity are critical.

Digital Isolators Replacement Considerations

The MAX14932AAWE+ offers similar isolation but operates at 1 Mbps. The MAX14932EAWE+ provides higher speed at 25 Mbps. Verify pinout compatibility before substituting, as channel configurations may differ across the series.
