Texas Instruments no longer manufactures this specific variant, so new-production orders through the factory channel are not available. ## 50 mV hysteresis and half-duplex — what they mean on the bus The 50 mV receiver hysteresis gives the SN75176BD a clean switching threshold on long cable runs where common-mode noise can blur the differential signal. In a half-duplex topology, the driver and receiver share the same pair of wires, so the microcontroller must manage the driver enable pin — typically tied to a UART's DE signal — to avoid bus contention. The 5V supply rail is standard for legacy RS-485 networks; if your system uses 3.3V logic, you will need level translation or a different transceiver.","metaTitle":"SN75176BD RS-485 Transceiver, 5V, Half-Duplex, 8-SOIC","metaDescription":"SN75176BD is a half-duplex RS-422/RS-485 transceiver in an 8-SOIC package, rated 0°C to 70°C, 4.75V to 5.25V supply.","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":"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":"$1.5900","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/49f2ca3304db8af27bb3b4611dc6c0e0.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/SN75176BD/alternatives.json"},"ai":{"faq":[{"question":"Is the SN75176BD obsolete?","answer":"Yes, the SN75176BD is listed as Obsolete.
