This is suitable for isolated SPI, UART, and slow fieldbus links, but not for high-speed interfaces like USB or gigabit Ethernet."},{"question":"Does MAX14931AASE+ work with both 3.3V and 5V logic?","answer":"Yes, the supply range on each side is 1.71 V to 5.5 V, so it operates directly with 3.3 V and 5 V logic without external level translation."},{"question":"Does MAX14931AASE+ require an external supply?","answer":"No, the MAX14931AASE+ does not include an integrated isolated DC-DC converter. Each side of the isolation barrier needs its own supply rail within the 1.71 V to 5.5 V range."},{"question":"What is the common-mode transient immunity (CMTI) for MAX14931AASE+?","answer":"The typical common-mode transient immunity is 25 kV/µs. This rating ensures reliable data transmission in high-dv/dt environments such as motor drives and switching power supplies."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/MAX14931AASE~3","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/MAX14931AASE~3 when reusing this data.
