There is no last-time-buy notice, no end-of-life risk for current production. For BOM-freeze planning, this is the kind of part you can qualify without worrying about a PCN landing next quarter. ## Package and temperature grade — board-fit notes The 8-SOIC package has a 3.90 mm body width. The -40°C to 85°C operating range suits industrial enclosures and outdoor cabinets. Supply is 5V nominal.","metaTitle":"MAX490EESA+ RS-485/RS-422 Transceiver, Full Duplex, 2.5 Mbps","metaDescription":"MAX490EESA+ full-duplex RS-485/RS-422 transceiver from Analog Devices. 2.5 Mbps data rate, 70 mV hysteresis, -40°C to 85°C range.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Type":"Transceiver","Duplex":"Full","Package":"Tube","Protocol":"RS422, RS485","Data Rate":"2.5Mbps","Mounting Type":"Surface Mount","Package / Case":"8-SOIC (0.154\\\", 3.90mm Width)","lifecycle_stage":"eol_hot","Voltage - Supply":"4.75V ~ 5.25V","Receiver Hysteresis":"70 mV","Operating Temperature":"-40°C ~ 85°C","Supplier Device Package":"8-SOIC","Number of Drivers/Receivers":"1/1"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$6.95","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$6.95000","currency":"USD"},{"qty":10,"price":"$6.27600","currency":"USD"},{"qty":25,"price":"$5.98360","currency":"USD"},{"qty":100,"price":"$5.19560","currency":"USD"},{"qty":250,"price":"$4.96212","currency":"USD"},{"qty":500,"price":"$4.52430","currency":"USD"},{"qty":1000,"price":"$3.94052","currency":"USD"},{"qty":2500,"price":"$3.79457","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/44b4a4b2553f52a56d8665981e25a7bf.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the data rate of MAX490EESA+?","answer":"The MAX490EESA+ supports a data rate of 2.5 Mbps, which covers Modbus RTU at common baud rates and most industrial RS-485 links up to a few hundred metres."},{"question":"Is MAX490EESA+ full duplex?","answer":"Yes, the MAX490EESA+ is a full-duplex transceiver with one driver and one receiver. It requires two twisted pairs for simultaneous transmit and receive, unlike half-duplex parts that share one pair and need direction control."},{"question":"Is MAX490EESA+ compatible with 3.3V logic?","answer":"The supply range is 4.75V to 5.25V, so the part is a 5V device. The logic inputs are 5V-tolerant, but a 3.3V UART may not meet the VIH threshold without a level shifter or open-drain buffer with pull-up to 5V."},{"question":"What is the difference between MAX490EESA+ and MAX490ESA+?","answer":"The 'E' in MAX490EESA+ denotes the extended temperature range (-40°C to 85°C), while the MAX490ESA+ is specified for the commercial temperature range (0°C to 70°C). Electrically they are identical — same data rate, same duplex, same pinout. Choose the 'E' variant for industrial or outdoor environments."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/MAX490EESA","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/MAX490EESA when reusing this data.
