It integrates one differential driver and one differential receiver in an 8-pin DIP package. Full-duplex operation means the driver and receiver are active simultaneously, using separate twisted pairs for transmit and receive. This is the right choice for point-to-point links where bidirectional traffic flows without bus turnaround delays. Supply voltage is 4.75 V to 5.25 V — a single 5 V rail. The 50 mV receiver hysteresis filters noise on long cable runs, reducing the chance of false edge triggers on the RX line. ## Temperature grade and package — commercial, through-hole, breadboard-friendly It is suited for indoor equipment, lab instruments, and office automation — not for engine bays, outdoor telecom cabinets, or factory-floor enclosures without climate control. The 8-DIP (0.300\", 7.62 mm) through-hole package is breadboard- and protoboard-friendly. It is also easier to hand-solder and rework than a surface-mount SOIC, which matters for low-volume builds and repair scenarios. ## Lifecycle and supply posture — active, no end-of-life signal Sourced per RFQ against your BOM quantity.","metaTitle":"SN75179BP RS-422/RS-485 Full-Duplex Transceiver, 8-DIP","metaDescription":"Texas Instruments SN75179BP transceiver — full-duplex, RS-422/RS-485, 1/1 driver/receiver, 4.75V–5.25V supply, 50 mV hysteresis, 0°C–70°C, 8-DIP.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Sensors & Transducers"],"specifications":{"Type":"Transceiver","Duplex":"Full","Package":"Tube","Protocol":"RS422, RS485","Mounting Type":"Through Hole","Package / Case":"8-DIP (0.300\\\", 7.62mm)","lifecycle_stage":"eol_hot","Voltage - Supply":"4.75V ~ 5.25V","Receiver Hysteresis":"50 mV","Operating Temperature":"0°C ~ 70°C","Supplier Device Package":"8-PDIP","Number of Drivers/Receivers":"1/1"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.22","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$3.22000","currency":"USD"},{"qty":10,"price":"$2.88900","currency":"USD"},{"qty":25,"price":"$2.73080","currency":"USD"},{"qty":100,"price":"$2.36670","currency":"USD"},{"qty":250,"price":"$2.24536","currency":"USD"},{"qty":500,"price":"$2.01474","currency":"USD"},{"qty":1000,"price":"$1.71750","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/abe3125c927451bf35b5b990d74f5e69.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Does SN75179BP support full-duplex RS-485?","answer":"Yes, the SN75179BP is a full-duplex transceiver. It can transmit and receive simultaneously on separate wire pairs, which is standard for RS-422 and also valid for RS-485 networks where the bus is wired for full-duplex operation."},{"question":"What is the difference between SN75179BP and SN75176BP?","answer":"The SN75179BP is full-duplex (separate driver and receiver enable pins, simultaneous TX/RX), while the SN75176BP is half-duplex (shared TX/RX lines with a single enable pin). Both use the same 8-DIP footprint and 5 V supply, but the SN75176BP requires bus turnaround control in firmware. The SN75179BP eliminates that overhead for bidirectional links."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/SN75179BP","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/SN75179BP when reusing this data.
