This is the right tier for Modbus RTU, BACnet MS/TP, and similar fieldbus protocols that top out at 115.2 kbps or 250 kbps. If your design requires 1 Mbps or higher (e.g., Profibus), you would step up to a different transceiver in the 65HVD family. ## Receiver hysteresis — noise budget on the cable The 60 mV of receiver hysteresis sets the input switching threshold deadband, preventing the output from chattering when the differential bus voltage sits near the threshold. On a typical RS-485 bus with termination resistors and common-mode noise from motor drives, this margin buys you reliable data without external biasing resistors or a separate fail-safe circuit. The hysteresis value is fixed — no external adjustment — so the board layout just needs the standard 120 Ω termination at each end of the stub. This part is not AEC-Q100 qualified; for automotive-rated RS-485, look at the SN65HVD88x-Q1 variants. No PCN watch is needed for this part today, but as with any active semiconductor, the BOM should include a qualified second source if the design is long-life.","metaTitle":"Texas Instruments SN65HVD888DR RS-485/RS-422 Transceiver","metaDescription":"TI SN65HVD888DR half-duplex RS-485/RS-422 transceiver in 8-SOIC. 250 kbps data rate, 60 mV hysteresis, 4.5V–5.5V supply, -40°C to 85°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Interface & Transceivers"],"specifications":{"Mfr":"Texas Instruments","Type":"Transceiver","Duplex":"Half","Series":"-","Package":"Tape & Reel (TR); Cut Tape (CT)","Protocol":"RS422, RS485","Data Rate":"250kbps","Mounting Type":"Surface Mount","Package / Case":"8-SOIC (0.154\\\", 3.90mm Width)","Product Status":"Active","lifecycle_stage":"eol_hot","Voltage - Supply":"4.5V ~ 5.5V","Base Product Number":"65HVD888","Receiver Hysteresis":"60 mV","Operating Temperature":"-40°C~85°C","Supplier Device Package":"8-SOIC","Number of Drivers/Receivers":"1/1"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.5300","priceTiers":[{"qty":1,"price":"$2.53000","currency":"USD"},{"qty":10,"price":"$2.27500","currency":"USD"},{"qty":25,"price":"$2.14640","currency":"USD"},{"qty":100,"price":"$1.82880","currency":"USD"},{"qty":250,"price":"$1.71720","currency":"USD"},{"qty":500,"price":"$1.50256","currency":"USD"},{"qty":1000,"price":"$1.24497","currency":"USD"},{"qty":2500,"price":"$1.21500","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/be0d29d0b6c36c200324719aa0afb51b.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/SN65HVD888DR/alternatives.json"},"ai":{"faq":[{"question":"What is the difference between SN65HVD888DR and SN65HVD888D?","answer":"The SN65HVD888DR and SN65HVD888D are electrically identical — same half-duplex RS-485/RS-422 transceiver, same 250 kbps data rate, same 60 mV hysteresis, same 8-SOIC package. The only difference is the shipping medium: the 'DR' suffix indicates Tape & Reel packaging, while the 'D' suffix typically ships in tubes. For a pick-and-place production line, the DR (reel) version is the standard choice; for hand-assembly or low-volume prototypes, the D (tube) version may be more convenient."},{"question":"Is SN65HVD888DR a direct replacement for SN65HVD888?","answer":"Yes. The SN65HVD888DR is the Tape & Reel packaging variant of the base SN65HVD888 part. The die, electrical specifications, and 8-SOIC footprint are identical. If your BOM calls for the SN65HVD888 (tube) but you have reel feeders, the DR suffix is a drop-in substitute — just verify the reel quantity matches your line setup."},{"question":"Is SN65HVD888DR lead-free and RoHS compliant?","answer":"Yes, the SN65HVD888DR is ROHS3 compliant, meaning it meets the EU RoHS directive without any exempted substances.
