MAX14931CASE+

Digital Isolators Overview

The MAX14931CASE+ is a general-purpose digital isolator manufactured by Analog Devices Inc./Maxim Integrated. It features four independent channels with a 3/1 input/output configuration, providing 2750Vrms isolation voltage. The device supports data rates up to 150Mbps and offers a typical common-mode transient immunity (CMTI) of 25kV/µs. It operates on supply voltages ranging from 1.71V to 5.5V and functions within an industrial temperature range of -40°C to +125°C. The component is housed in a 16-SOIC package with a width of 3.90mm.

Digital Isolators Feature Summary

• Provides galvanic isolation for high-speed digital signals using capacitive coupling technology.
• Supports flexible channel configurations with three inputs and one output arrangement.
• Ensures signal integrity through high common-mode transient immunity capabilities.
• Operates reliably across extended industrial temperature ranges.

Digital Isolators Applications

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

Digital Isolators Procurement Notes

Verify the specific suffix 'CASE+' matches the required tape-and-reel or tube packaging format for your assembly line. Confirm that the 16-SOIC footprint dimensions align with your PCB layout constraints. Ensure the manufacturer designation corresponds to the current Analog Devices or Maxim Integrated sourcing channel to guarantee authenticity and traceability.

Digital Isolators Selection Notes

Select this component when a 3/1 channel configuration is specifically required rather than symmetric layouts. Consider the 150Mbps speed limit against system timing requirements. Evaluate the 2750Vrms isolation rating against safety standards applicable to the target application environment.

Digital Isolators Part Context

This part belongs to the MAX1493x family of digital isolators, which utilizes capacitive coupling for signal transmission. The family includes variants with different channel counts and speeds, such as the MAX14930 and MAX14931. These devices are designed to replace traditional optocouplers in space-constrained designs.

Digital Isolators Replacement Considerations

MAX14930CASE+ is a verified substitute offering identical 4-channel symmetric configuration and similar electrical characteristics within the same package.

Digital Isolators FAQ

What is the maximum data rate supported by the MAX14931CASE+?
