MAX14931FASE+CZ1

Digital Isolators Overview

The MAX14931FASE+CZ1 is a general-purpose digital isolator featuring four independent channels in a 3/1 input-output configuration. It utilizes capacitive coupling technology to provide electrical isolation with a rated voltage of 2750Vrms. The device supports data rates up to 150Mbps and offers a typical common-mode transient immunity (CMTI) of 25kV/µs. It operates within a supply voltage range of 1.71V to 5.5V and functions across an extended temperature range from -40°C to +125°C. The component is housed in a narrow 16-SOIC package.

Digital Isolators Feature Summary

Digital Isolators Procurement Notes

Verify the specific suffix CZ1 against official Analog Devices documentation to confirm pinout and functional compatibility. Ensure the procurement source provides valid RoHS compliance certificates. Cross-reference the datasheet revision date to ensure alignment with current manufacturing specifications before finalizing orders.

Digital Isolators Selection Notes

Select this component when a 3/1 channel configuration is required for mixed-signal isolation. It is suitable for applications demanding high CMTI performance in noisy environments. Consider the narrow SOIC footprint for space-constrained PCB layouts. Validate that the operating voltage range matches the system's logic levels.

Digital Isolators Part Context

This part belongs to the MAX1493x family of digital isolators manufactured by Maxim Integrated, now part of Analog Devices. The family shares similar capacitive coupling technology but varies in channel count and configuration. The MAX14931 specifically addresses applications needing asymmetric channel distribution.

Digital Isolators Replacement Considerations

MAX14931CAWE+T and MAX14931CASE+ are alternative variants within the same product family. Verify package width differences and suffix-specific electrical tolerances before substitution.
