TSB81BA3DPFP

Drivers, Receivers, Transceivers Overview

The TSB81BA3DPFP is an IEEE 1394b three-port cable transceiver and arbiter manufactured by Texas Instruments. It operates on a single 3.3 V power supply and supports data rates up to 1000 Mbps. The device features three transmit channels and three receive channels, housed in an 80-pin HTQFP surface-mount package with dimensions of 12.2 x 12.2 x 1.05 mm. It functions within a commercial temperature range from 0 °C to +70 °C.

Drivers, Receivers, Transceivers Feature Summary

• Integrates three independent cable transceivers for simultaneous multi-port connectivity
• Includes built-in arbitration logic for managing bus access among multiple nodes
• Supports high-speed serial communication compliant with IEEE 1394b standards

Drivers, Receivers, Transceivers Applications

• High-performance storage area networks (SANs)
• Industrial automation control systems requiring reliable serial communication
• Professional audio and video equipment interfaces

Drivers, Receivers, Transceivers Procurement Notes

Verify the complete part number including the suffix against official Texas Instruments documentation to ensure correct package type and temperature rating. Confirm that the supplier provides traceability to the original manufacturer. Request the specific datasheet revision to validate pinout compatibility and electrical characteristics before integration into the design.

Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring multiple IEEE 1394b ports within a single integrated circuit. Ensure the application environment remains within the specified 0 °C to +70 °C operating range. Verify that the system power supply strictly adheres to the 3.3 V requirement to maintain signal integrity and prevent damage to the internal transceiver circuits.

Drivers, Receivers, Transceivers Part Context

This component belongs to the TSB81BA3 family of IEEE 1394b controllers. Variants such as TSB81BA3D or TSB81BA3DI share similar functional architectures but may differ in package style or industrial temperature ratings. The DPFP suffix specifically denotes the 80-pin HTQFP plastic package configuration used for surface-mount assembly.
