At 5 Mbps the SN65HVD34DR can sustain a 200-meter cable run with proper termination, though practical reach shortens as the baud rate climbs. The full-duplex capability means separate pairs for transmit and receive, eliminating the bus-turnaround dead time that half-duplex parts incur. No LTB window to track, no forced redesign for a replacement.","metaTitle":"SN65HVD34DR RS-485/RS-422 Transceiver, 5 Mbps, 3.3V","metaDescription":"Texas Instruments SN65HVD34DR full-duplex RS-485/RS-422 transceiver in 14-SOIC. 5 Mbps data rate, 3V–3.6V supply, 50 mV hysteresis, –40°C to 85°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Interface & Transceivers"],"specifications":{"Mfr":"Texas Instruments","Type":"Transceiver","Duplex":"Full","Series":"-","Package":"Tape & Reel (TR); Cut Tape (CT)","Protocol":"RS422, RS485","Data Rate":"5Mbps","Mounting Type":"Surface Mount","Package / Case":"14-SOIC (0.154\\\", 3.90mm Width)","Product Status":"Active","lifecycle_stage":"eol_hot","Voltage - Supply":"3V ~ 3.6V","Base Product Number":"65HVD34","Receiver Hysteresis":"50 mV","Operating Temperature":"-40°C~85°C","Supplier Device Package":"14-SOIC","Number of Drivers/Receivers":"1/1"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$4.5400","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/b478029e1adc17f2a0ac5127fa8c6674.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/SN65HVD34DR/alternatives.json"},"ai":{"faq":[{"question":"Which is better, SN65HVD34DR or SN65HVD35DR?","answer":"The SN65HVD34DR is a full-duplex transceiver; the SN65HVD35DR is half-duplex. The choice depends on whether your bus needs separate transmit and receive pairs (full-duplex) or a shared pair with direction control (half-duplex).
