MAX14932CASE+

Digital Isolators Overview

The MAX14932CASE+ is a four-channel digital isolator from the MAX14930–MAX14932 family, manufactured by Analog Devices Inc./Maxim Integrated. It provides bidirectional signal isolation with a rated insulation voltage of 2750Vrms. The device supports data rates up to 150Mbps and features a typical common-mode transient immunity (CMTI) of 25kV/µs. It operates on a single supply voltage ranging from 1.71V to 5.5V and functions within an industrial temperature range of -40°C to +125°C. Packaged in a 16-pin SOIC (0.154 inch width), it utilizes capacitive coupling technology for robust noise rejection.

Digital Isolators Feature Summary

• Provides galvanic isolation between circuits using high-reliability capacitive coupling technology.
• Supports high-speed data transmission with a maximum rate of 150Mbps per channel.
• Features high common-mode transient immunity to maintain signal integrity in noisy environments.
• Offers flexible configuration options including 4/0 or 2/2 channel layouts.

Digital Isolators Applications

• Industrial automation systems requiring isolated communication interfaces
• Medical equipment needing patient isolation barriers
• Power electronics control circuits with high-voltage isolation requirements

Digital Isolators Procurement Notes

Verify component authenticity through authorized distributors due to limited availability status. Confirm package variant matches design specifications as suffixes indicate specific tape-and-reel or tube packaging configurations. Ensure compliance with RoHS directives and check for obsolescence notices before finalizing procurement plans.

Digital Isolators Selection Notes

Select this part when 2750Vrms isolation is sufficient for the application safety requirements. Compare against MAX14930CASE+ if higher speed is needed, or MAX14931CASE+ for different channel configurations. Verify that the 16-SOIC footprint fits the PCB layout constraints and that the operating voltage range aligns with the system power rails.

Digital Isolators Part Context

This component belongs to the MAX1493x series of general-purpose digital isolators. It shares architectural similarities with the MAX1413x series but offers enhanced performance metrics. The MAX14932CASE+ specifically targets applications requiring moderate speed and standard isolation ratings in a compact surface-mount package.

Digital Isolators Replacement Considerations

Direct substitutes include MAX14930CASE+ for higher speed needs or MAX14931CASE+ for different channel splits. Cross-reference pinouts and electrical characteristics carefully to ensure compatibility with existing circuit designs without modification.
