The 130 mV of receiver hysteresis cleans up noisy lines without external filtering. ## 25 Mbps — is it overkill for your link? At 25 Mbps the SN65HVD23DR can clock a 400-meter run at lower baud rates or a short stub at full speed. For typical fieldbus applications (115.2 kbps to 1 Mbps) it has plenty of margin, so you are not pushing the driver into slew-rate limiting. If your bus is strictly 250 kbps or below, a slower slew-limited transceiver like the SN65HVD3082E might reduce EMI and reflections, but the 23DR's faster edges are fine with proper termination and stub lengths under 6 inches. For BOM resilience, the SOIC-8 footprint is shared across the SN65HVD2x family, so a pin-compatible swap (e.g., SN65HVD22 for full-duplex or SN65HVD24 for a different speed grade) is possible without a board spin.","metaTitle":"SN65HVD23DR RS-485/RS-422 Transceiver, 25 Mbps, SOIC-8","metaDescription":"TI SN65HVD23DR half-duplex RS-485/RS-422 transceiver, 25 Mbps data rate, 4.5V–5.5V supply, -40°C to 85°C, SOIC-8.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Interface & Transceivers"],"specifications":{"Mfr":"Texas Instruments","Type":"Transceiver","Duplex":"Half","Series":"-","Package":"Tape & Reel (TR)","Protocol":"RS422, RS485","Data Rate":"25Mbps","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":"65HVD23","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":"$2.7330","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/bd0d8e36e12ed062757287fb6e2338d5.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/SN65HVD23DR/alternatives.json"},"ai":{"faq":[{"question":"What is the data rate of SN65HVD23DR?","answer":"The data rate is 25 Mbps.
