It integrates one driver and one receiver, with 70 mV of receiver hysteresis. ## Commercial temperature grade — deployment boundary Rated 0°C to 70°C, this part is intended for office, lab, and climate-controlled industrial enclosures. It is not suited for outdoor telecom cabinets, engine bays, or freezer environments where the ambient can drop below freezing. For extended temperature needs, look at the industrial-grade variants in the same family. ## Active production — no LTB risk The MAX490ECSA+T carries an Active product status with ROHS3 compliance.","metaTitle":"MAX490ECSA+T RS-485/RS-422 Transceiver, 2.5 Mbps","metaDescription":"MAX490ECSA+T is a Maxim Integrated RS-485/RS-422 full-duplex transceiver in 8-SOIC.

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/MAX490ECSAT","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/MAX490ECSAT when reusing this data.
