Supply voltage spans 3 V to 5.5 V, covering both 3.3 V and 5 V industrial logic rails without a separate level translator. The 50 mV receiver hysteresis filters noise on long cable runs — a practical margin for factory-floor RS485 buses where ground potential differences and EMI are common. Operating temperature range -40°C to 125°C covers industrial enclosures and engine-bay applications where ambient heat exceeds 85°C. ## Package and PCB integration Housed in a SOT-583 package (1.6 mm × 1.6 mm, 8-pin), the THVD1420DRLR is a surface-mount device suited for dense PCB layouts where board space is at a premium. The small footprint demands a tight decoupling layout — place a 100 nF ceramic cap within 2 mm of the supply pin to keep the transceiver's edge rates clean on the 12 Mbps bus. ## Lifecycle and sourcing posture Sourced through independent distribution channels; availability and current pricing confirmed at RFQ for the BOM quantity.","metaTitle":"THVD1420DRLR RS485 Transceiver, 12 Mbps, SOT-583","metaDescription":"Texas Instruments THVD1420DRLR half-duplex RS422/RS485 transceiver, 12 Mbps data rate, 3V–5.5V supply, -40°C to 125°C, SOT-583 package.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"Not applicable","productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Type":"Transceiver","Duplex":"Half","Package":"Tape & Reel (TR); Cut Tape (CT)","Protocol":"RS422, RS485","Data Rate":"12Mbps","Mounting Type":"Surface Mount","Package / Case":"SOT-583","lifecycle_stage":"eol_hot","Voltage - Supply":"3V ~ 5.5V","Receiver Hysteresis":"50 mV","Operating Temperature":"-40°C ~ 125°C (TA)","Supplier Device Package":"SOT-583","Number of Drivers/Receivers":"1/1"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.42","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$1.42000","currency":"USD"},{"qty":10,"price":"$1.26700","currency":"USD"},{"qty":25,"price":"$1.20240","currency":"USD"},{"qty":100,"price":"$0.98780","currency":"USD"},{"qty":250,"price":"$0.92336","currency":"USD"},{"qty":500,"price":"$0.81600","currency":"USD"},{"qty":1000,"price":"$0.64421","currency":"USD"},{"qty":4000,"price":"$0.60126","currency":"USD"},{"qty":8000,"price":"$0.57120","currency":"USD"},{"qty":12000,"price":"$0.54972","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/29cdd124ace64a32a46f48869e5f172f.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is THVD1420DRLR a drop-in replacement for SN65HVD233MDREP?","answer":"No. The SN65HVD233MDREP is a CANbus transceiver (1 Mbps, -55°C to 125°C), while the THVD1420DRLR is an RS485/RS422 transceiver (12 Mbps, -40°C to 125°C).
