It handles one driver and one receiver in a 14-SOIC surface-mount package, with a maximum data rate of 250 kbps. The supply range is 4.75 V to 5.25 V, so it runs on a 5 V nominal rail—not 3.3 V. Operating temperature is 0°C to 70°C, making it a commercial-grade part for indoor equipment, office peripherals, and appliance control boards. ## Key ratings and what they mean for the BOM Data rate of 250 kbps is the practical ceiling for this transceiver. At that speed, the rise/fall times are slew-limited, which keeps radiated emissions low—useful for passing FCC/CE without extra filtering. If your bus runs at 115.2 kbps or below, this part has comfortable margin. Receiver hysteresis of 70 mV provides noise immunity on long cable runs. In a typical RS-485 network with 100 m of twisted pair, that hysteresis prevents chatter from ground shifts and reflections. Supply voltage is strictly 5 V ±5%. Do not try 3.3 V—the part is not specified there. Verify your rail is within 4.75 V to 5.25 V, especially if the board has a 5 V LDO with dropout headroom issues. Temperature range 0°C to 70°C covers office, lab, and consumer environments. Not rated for -40°C or +85°C, so skip it for outdoor telecom or under-hood automotive. ## Lifecycle and sourcing reality The MAX489CSD+ carries an Active lifecycle status per the manufacturer. It remains a standard catalog item through Analog Devices' distribution network.","metaTitle":"MAX489CSD+ RS-422/RS-485 Transceiver, 250 kbps, Full Duplex","metaDescription":"MAX489CSD+ is an Analog Devices full-duplex RS-422/RS-485 transceiver in 14-SOIC. 250 kbps data rate, 4.75 V to 5.25 V supply, commercial temp.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["DC-DC Power Modules"],"specifications":{"Type":"Transceiver","Duplex":"Full","Package":"Tube","Protocol":"RS422, RS485","Data Rate":"250kbps","Mounting Type":"Surface Mount","Package / Case":"14-SOIC (0.154\\\", 3.90mm Width)","lifecycle_stage":"eol_hot","Voltage - Supply":"4.75V ~ 5.25V","Receiver Hysteresis":"70 mV","Operating Temperature":"0°C ~ 70°C","Supplier Device Package":"14-SOIC","Number of Drivers/Receivers":"1/1"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$4.2","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$4.20000","currency":"USD"},{"qty":10,"price":"$3.77400","currency":"USD"},{"qty":25,"price":"$3.56800","currency":"USD"},{"qty":100,"price":"$3.09210","currency":"USD"},{"qty":250,"price":"$2.93356","currency":"USD"},{"qty":500,"price":"$2.63226","currency":"USD"},{"qty":1000,"price":"$2.21998","currency":"USD"},{"qty":2500,"price":"$2.10898","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/602428fed3abfc9496453e492ef2d17c.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is MAX489CSD+ compatible with 5V supply?","answer":"Yes, it is designed for a 5 V supply rail, with a specified range of 4.75 V to 5.25 V.
