Application Scenarios & Design Considerations

IEEE P1394b s800 Three-Port Cable Transceiver/Arbiter

Alternative Part Number

  • TSB41AB3PFP --: Same TSB41 series IEEE 1394 (FireWire) transceiver family in the same HTQFP-80 PFP package, with closely matching pinout and function, making it a strong drop-in candidate.
  • TSB43AB23PFP --: TI IEEE 1394 link-layer controller in the same PFP package with comparable interface and supply requirements, suitable when the integrated 1394 link/PHY function is needed.
  • TSB82AA2PFP --: Another TI 1394 controller in the same PFP package family, offering similar FireWire connectivity for designs where the exact TSB81BA3 variant is unavailable.
