For existing BOM lines already using the SN75176AD, this is the time to secure lifetime-buy quantities or identify a drop-in replacement before the last shipment window closes. ## Package and field-swap notes This is an 8-SOIC surface-mount part (3.90 mm body width). No lab bench needed for a swap if you have a hot-air station and steady hands — the pin pitch is fine but the package is well marked. Pin 1 orientation is standard (dot or notch at the top-left when the part number reads left to right). ## What the 50 mV hysteresis means on the bus The 50 mV of receiver hysteresis is the spec that determines how cleanly the part rejects noise on a long RS485 stub. On a 100 m cable run with marginal termination, that hysteresis prevents the receiver from chattering on reflections. If your bus is running at 250 kbps or below over twisted pair in a noisy electrical cabinet, this part handles it. At higher data rates or with poor grounding, you might need a part with wider hysteresis or a failsafe bias — but for the classic industrial RS485 point-to-point or multi-drop, 50 mV is the standard sweet spot.","metaTitle":"SN75176AD RS485 Transceiver, Half-Duplex, 8-SOIC, Last Buy","metaDescription":"Texas Instruments SN75176AD half-duplex RS422/RS485 transceiver in 8-SOIC. 4.75V-5.25V supply, 50 mV hysteresis, 0-70°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Last Buy","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":"Last Time Buy","lifecycle_stage":"eol_hot","Voltage - Supply":"4.75V ~ 5.25V","Base Product Number":"75176","Receiver Hysteresis":"50 mV","Operating Temperature":"0°C~70°C","Supplier Device Package":"8-SOIC","Number of Drivers/Receivers":"1/1"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.3000","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/cd28479fa36e72905729956045f9287a.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/SN75176AD/alternatives.json"},"ai":{"faq":[{"question":"What is the difference between SN75176A and SN75176AD?","answer":"The 'D' suffix on SN75176AD indicates the 8-SOIC surface-mount package. The SN75176A (no D) is the same die in a DIP package. Electrically they are identical — same 50 mV hysteresis, same 5 V supply, same 1/1 driver/receiver count.
