Product details

IEEE 1394 transceiver for legacy FireWire links

The TSB81BA3EIPFP is a Texas Instruments IEEE 1394 transceiver operating in half-duplex mode, with six drivers and six receivers on a single 80-TQFP Exposed Pad package (80-HTQFP 12x12). 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.

Frequently asked questions

Is TSB81BA3EIPFP compatible with IEEE 1394b?

The part is listed under the IEEE 1394 protocol, which covers both 1394a and 1394b data rates. The half-duplex and 6/6 driver/receiver count are consistent with a 1394b PHY implementation, but confirm the exact data-rate support (S100/S200/S400) from the full datasheet.

Is TSB81BA3EIPFP obsolete?

No — the product status is Active. Texas Instruments continues to manufacture this part, so it is suitable for both new designs and ongoing production.
