Full-duplex operation means the driver and receiver are active simultaneously, so the part can transmit and receive on separate twisted pairs without direction switching. This simplifies the firmware compared to half-duplex parts that need a transmit-enable toggle on every packet.","metaTitle":"MAX489EESD+T RS-485/RS-422 Transceiver, 250 kbps, 14-SOIC","metaDescription":"MAX489EESD+T Analog Devices full-duplex RS-485/RS-422 transceiver, 250 kbps data rate, 70 mV hysteresis, -40 to +85°C, 14-SOIC.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Type":"Transceiver","Duplex":"Full","Package":"Tape & Reel (TR); Cut Tape (CT)","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":"-40°C ~ 85°C","Supplier Device Package":"14-SOIC","Number of Drivers/Receivers":"1/1"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$7.74","priceTiers":[{"qty":1,"price":"$7.74000","currency":"USD"},{"qty":10,"price":"$6.98800","currency":"USD"},{"qty":25,"price":"$6.66240","currency":"USD"},{"qty":100,"price":"$5.78500","currency":"USD"},{"qty":250,"price":"$5.52500","currency":"USD"},{"qty":500,"price":"$5.03750","currency":"USD"},{"qty":1000,"price":"$4.87500","currency":"USD"},{"qty":2500,"price":"$4.87500","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/67a2fc5923ffc6043768df284f4cab78.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/MAX489EESD%2BT/alternatives.json"},"ai":{"faq":[{"question":"What protocols does MAX489EESD+T support?","answer":"It supports both RS-422 and RS-485 protocols in full-duplex mode.
