MAX14931EASE+T

Digital Isolators Overview

The MAX14931EASE+T is a general-purpose digital isolator featuring four independent channels configured in a 3/1 arrangement. It utilizes capacitive coupling technology to provide electrical isolation with a rated insulation voltage of 2750 Vrms. The device supports data transmission rates up to 25 Mbps and exhibits a typical common-mode transient immunity (CMTI) of 25 kV/µs. Operating within a supply voltage range of 1.71 V to 5.5 V, it ensures signal integrity across wide temperature ranges from -40°C to +125°C. Packaged in a 16-pin SOIC-Narrow footprint, this component is designed for robust performance in industrial applications requiring reliable galvanic isolation.

Digital Isolators Procurement Notes

Verify the specific suffix EASE+T to confirm the narrow SOIC package and tape-and-reel or cut-tape availability. Ensure compatibility with the 1.71 V to 5.5 V supply range during integration. Confirm RoHS compliance status as per the latest manufacturer documentation before finalizing procurement orders.

Digital Isolators Selection Notes

Select this component when a 3/1 channel configuration is required for asymmetric data flow. Consider the 25 Mbps speed limit against higher-speed alternatives if system latency is critical. Evaluate the 2750 Vrms 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 from Analog Devices/Maxim Integrated. The series offers various channel counts and configurations to suit different interface needs. The MAX14931 specifically addresses applications needing multiple input lines isolated to a single output path.

Digital Isolators Replacement Considerations

Check for direct pin-compatible substitutes within the MAX1493x series such as the MAX14930 or MAX14932, ensuring identical channel configurations and electrical specifications match the design requirements.
