Standard land patterns from IPC-7351 or the manufacturer's datasheet apply. No special thermal pad or via array is required for this low-power transceiver."},{"question":"What is the difference between MAX490 and MAX485?","answer":"The MAX490 is a full-duplex transceiver (separate driver and receiver pins for simultaneous transmit and receive), while the MAX485 is half-duplex (shared bus lines, direction control via DE/RE). Both operate at up to 2.5 Mbps and use the same 5 V supply, but they are not pin-compatible for full-duplex designs."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/MAX490ECSA~3T","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/MAX490ECSA~3T when reusing this data.
