Texas Instruments and Accelerated Designs, Inc. have collaborated together to provide TI customers with schematic symbols and PCB layout footprints for TI products.

Please follow the instructions below to view the CAD symbols:

Step 1: Download and install the Ultra Librarian software

Step 2: Download the Symbol and Footprint from the CAD.bxl file table.

Step 3: Open the .bxl file with the Ultra Librarian software.

You can always access the complete CAD/CAE Symbols database at //webench.ti.com/cad/

Both PCB footprints and schematic symbols are available for download in a vendor neutral format, which can then be exported to the leading EDA CAD/CAE design tools using the Ultra Librarian Reader. The reader is available as a free download.

The UL Reader is a subset of the Ultra Librarian toolset that can generate, import, and export components and their attributes in virtually any EDA CAD/CAE format.
