It will not run on a 3.3 V rail — if your system is 3.3 V only, you need a different transceiver (the SN65HVD30 family operates at 3.3 V). ## 25 Mbps full-duplex — what the data rate and duplex mode mean for your bus Full-duplex operation means the SN65HVD50D can transmit and receive simultaneously, using separate twisted pairs. This doubles the throughput compared to half-duplex RS485 implementations that must arbitrate the bus direction. At 25 Mbps, the bit period is 40 ns — the driver slew rate is fast enough to hit that rate, but you need controlled-impedance cabling (120 Ω termination) and stub lengths kept under a few inches to avoid reflections. The single driver and single receiver (1/1 count) match point-to-point or small multi-drop topologies. For larger multi-drop networks with more than 32 unit loads, consider a transceiver with higher receiver input impedance. ## Package and footprint — 8-SOIC narrow-body land pattern Standard SOIC-8 footprint; no thermal pad to worry about.","metaTitle":"SN65HVD50D RS485/RS422 Transceiver, 25Mbps, Full-Duplex","metaDescription":"TI SN65HVD50D full-duplex RS485/RS422 transceiver, 25Mbps data rate, 4.5V-5.5V supply, 50mV hysteresis, -40°C to 85°C, 8-SOIC.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Interface & Transceivers"],"specifications":{"Mfr":"Texas Instruments","Type":"Transceiver","Duplex":"Full","Series":"-","Package":"Tube","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":"65HVD50","Receiver Hysteresis":"50 mV","Operating Temperature":"-40°C~85°C","Supplier Device Package":"8-SOIC","Number of Drivers/Receivers":"1/1"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$5.4400","priceTiers":[{"qty":1,"price":"$5.44000","currency":"USD"},{"qty":10,"price":"$4.88900","currency":"USD"},{"qty":25,"price":"$4.62200","currency":"USD"},{"qty":100,"price":"$4.00580","currency":"USD"},{"qty":250,"price":"$3.80040","currency":"USD"},{"qty":500,"price":"$3.41010","currency":"USD"},{"qty":1000,"price":"$2.90700","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/063ae81a5aee27e74db5665a0c710c2c.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/SN65HVD50D/alternatives.json"},"ai":{"faq":[{"question":"Can SN65HVD50D be used in a 3.3V system?","answer":"No. This transceiver requires a 5 V rail and will not function on 3.3 V.
