It sets the dead band between the logic thresholds, meaning the receiver won't chatter on a slowly rising differential signal or when ground potentials shift between nodes. For a 25 Mbps link over twisted-pair cable in a motor-drive cabinet, that hysteresis budget is what keeps the UART from seeing false edges. The SN65HVD20D carries a Last Buy lifecycle status. This means TI has issued an end-of-life notice and the part is on its final production run. Once the last-time-buy window closes, the only channel will be surplus and independent distribution.","metaTitle":"SN65HVD20D RS485/RS422 Transceiver, 25Mbps, 8-SOIC","metaDescription":"Texas Instruments SN65HVD20D half-duplex RS485/RS422 transceiver, 25 Mbps data rate, 130 mV receiver hysteresis, -40 to 85°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Last Buy","categoryPath":["Interface & Transceivers"],"specifications":{"Mfr":"Texas Instruments","Type":"Transceiver","Duplex":"Half","Series":"-","Package":"Tube","Protocol":"RS422, RS485","Data Rate":"25Mbps","Mounting Type":"Surface Mount","Package / Case":"8-SOIC (0.154\\\", 3.90mm Width)","Product Status":"Last Time Buy","lifecycle_stage":"eol_hot","Voltage - Supply":"4.5V ~ 5.5V","Base Product Number":"65HVD20","Receiver Hysteresis":"130 mV","Operating Temperature":"-40°C~85°C","Supplier Device Package":"8-SOIC","Number of Drivers/Receivers":"1/1"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$5.9100","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/bd0d8e36e12ed062757287fb6e2338d5.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/SN65HVD20D/alternatives.json"},"ai":{"faq":[{"question":"Is SN65HVD20D obsolete?","answer":"Yes, the SN65HVD20D is in a Last Buy lifecycle phase.
