Both share the same 16-TSSOP package, pinout, supply range, and 250 kbps data rate. Choose the EEUE+ for outdoor or factory-floor environments; the ECUE+ for indoor, climate-controlled equipment."},{"question":"Is MAX3221ECUE+ compatible with 3.3V logic?","answer":"Yes, the supply range of 3V to 5.5V covers 3.3V operation directly. You can power it from a 3.3V rail and interface with a 3.3V UART without extra level shifting."},{"question":"What are the equivalent parts for MAX3221ECUE+?","answer":"The closest pin-compatible equivalent is the MAX3221EEUE+, which differs only in temperature grade. For a different package or channel count, look at the MAX3221 family — but for a drop-in replacement in the 16-TSSOP footprint, the EEUE+ is the direct alternate."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/MAX3221ECUE","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/MAX3221ECUE when reusing this data.
