Any pin-compatible replacement must also accept a nominal 5V supply and maintain the same half-duplex, 1/1 driver/receiver configuration. The 50 mV receiver hysteresis is a typical value for this family — a replacement with lower hysteresis may be more susceptible to bus reflections on long stubs. ## Obsolete — sourcing the SN65176BD today","metaTitle":"SN65176BD RS422/RS485 Transceiver, 1/1 Driver/Receiver","metaDescription":"TI SN65176BD half-duplex RS422/RS485 transceiver. 5V supply, 50 mV hysteresis, -40 to 105°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Interface & Transceivers"],"specifications":{"Mfr":"Texas Instruments","Type":"Transceiver","Duplex":"Half","Series":"-","Package":"Tube","Protocol":"RS422, RS485","Data Rate":"-","Mounting Type":"Surface Mount","Package / Case":"8-SOIC (0.154\\\", 3.90mm Width)","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Voltage - Supply":"4.75V ~ 5.25V","Base Product Number":"65176","Receiver Hysteresis":"50 mV","Operating Temperature":"-40°C~105°C","Supplier Device Package":"8-SOIC","Number of Drivers/Receivers":"1/1"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.7300","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/49f2ca3304db8af27bb3b4611dc6c0e0.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/SN65176BD/alternatives.json"},"ai":{"faq":[{"question":"What is the replacement for the SN65176BD?","answer":"No official TI replacement part number is listed for the SN65176BD. A functionally equivalent replacement must be a half-duplex RS422/RS485 transceiver in an 8-SOIC package, operating from a 5V supply, with one driver and one receiver. Parts like the TI SN65HVD72 or SN65HVD3082E are in the same family but differ in supply range or pinout — verify compatibility against the original footprint and bus timing before substituting."},{"question":"Is the SN65176BD compatible with 5V RS485 systems?","answer":"Yes. The SN65176BD is designed for 5V RS485 and RS422 buses, with a supply range of 4.75V to 5.25V. It is a half-duplex transceiver with 50 mV receiver hysteresis, suitable for differential communication over twisted-pair cables in industrial environments."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/SN65176BD","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/SN65176BD when reusing this data.
