It is designed for FireWire node interfaces, hubs, or embedded controllers that need to maintain a 1394a/1394b physical-layer link without a separate PHY chip. ## Supply rail and temperature range for industrial BOMs The supply range is 3V to 3.6V, which means a 3.3V rail with ±10% tolerance covers it — no extra regulator needed if the board already runs a 3.3V plane. ## Package and footprint for layout review Surface-mount assembly with 0.50 mm pitch demands careful solder-paste stencil design and X-ray inspection to catch bridges between adjacent leads.","metaTitle":"TSB81BA3EIPFP IEEE 1394 Transceiver Half-Duplex 6/6 80HTQFP","metaDescription":"Texas Instruments TSB81BA3EIPFP IEEE 1394 transceiver, half-duplex, 6 drivers/6 receivers, 3V-3.6V supply, -40°C to 85°C, 80-TQFP Exposed Pad.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Sensors & Transducers"],"specifications":{"Type":"Transceiver","Duplex":"Half","Package":"Tray","Protocol":"IEEE 1394","Mounting Type":"Surface Mount","Package / Case":"80-TQFP Exposed Pad","lifecycle_stage":"eol_hot","Voltage - Supply":"3V ~ 3.6V","Operating Temperature":"-40°C ~ 85°C","Supplier Device Package":"80-HTQFP (12x12)","Number of Drivers/Receivers":"6/6"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$10.98","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$10.98000","currency":"USD"},{"qty":10,"price":"$9.91600","currency":"USD"},{"qty":25,"price":"$9.45480","currency":"USD"},{"qty":96,"price":"$8.20948","currency":"USD"},{"qty":288,"price":"$7.84049","currency":"USD"},{"qty":480,"price":"$7.14869","currency":"USD"},{"qty":960,"price":"$6.52650","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/e2be77b60fb20e799ff9d4f056c96786.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is TSB81BA3EIPFP compatible with IEEE 1394b?","answer":"The part is listed under the IEEE 1394 protocol, which covers both 1394a and 1394b data rates.
