SN74LVC1G3157: 2D and 3D .dxf File for DTB package (how to convert .bxl file into the format of your choice)

Part Number: SN74LVC1G3157

Dear Team,

Do we have 2D or 3D .dxf file as below figure that can provide to the customer? 

Thank you.

  • Jim,

    Please look at the CAD/CAE symbols provided in the quality and packaging information tab on TI.com.   

    Thank you,

    Adam

  • Hi Adam,

    sorry, our cad team can't use .bxl file, could you provide .dxf file for us

    thanks

  • Louis,

    The .bxl file is a vendor neutral file and should be compatible with most drawing programs.

    I looked at some other e2e posts and it looks like TI doesn't support .dxf files but you can create them yourself using the dimensions in the package drawings.

    Which program are you using that will not open the .bxl file?

    Thank you,
    Adam
  • Hi Adam,

    we are using autocad

    Can TI help to create .dxf file? otherwise we cannot use this part because our layout team create package drawings by ourselves.

  • Louis,

    You can convert the .bxl file to .dxf using the following steps.

    1) Download the .bxl file and ultra librarian software using the 3 step instructions on the packaging information tab on TI.com. 

    2) Open the .bxl file with the ultra librarian software and scroll down in the step 2, select tools menu and select DXF 2D or 3D.

    3) click export to selected tools button on the step 3 menu, export to Cad Tools.

    Thank you,

    Adam  

  • Hi Adam,

    Sorry, our notebook have some license problem, so we can't download  ultra librarian software 

    could you help us transfer .dxf file for us?

    thanks

  • No, this link is not what I need. I also need your help.

    1. I need to convert the .bxl file to altium designer form file. 

    2. After I use the Ultra Librarian software and complete the 3 steps. Then it exports the files which are in the figure 1. 

    3. Then I open the "readme.txt" file. I open the altium designer softeware and open and selecting the UL_Import.PrjScr file stored. Please check the figure 2.

    4. I copy the "readme.txt" file as below, you can read it:

    To import your new library part into Altium follow these steps:

    1). After running the Ultra Librarian export for the first time,
    you will need to copy the following files into an area where
    they can be accessed for all future translations. They are script
    files that Altium will need to be able to find.
    a. UL_Form.dfm
    b. UL_Form.pas
    c. UL_Import.pas
    d. UL_Import.prjScr

    2). The above script file will need to be run from within Altium.
    This can be done by going to File, Open and selecting the
    UL_Import.PrjScr file stored above.

    3). Select the UL_Form.pas file form the new project that has loaded,
    and then select runfrom the drop down menu. You will need to select
    the form again. Run the form.

    4). When the script is run, it will ask you for the file name of the
    Ultra Librarian file to run. You should select the latest file
    produced with a date code (for instance 2010-02-17_23-12-34.txt).

    5). The script will open a new Integraged Library project and import
    the Ultra Librarian data into it. When complete a message box
    will pop up saying that import is done.

    5. According to the 3) step, I cannot find the runfrom in the altium designer. You can also check the figure 2. I do not know how to do from the 3) step to the 5) step.

    So, would you please help me to check this problem and send me the screenshots?

                                                                                                           Figure 2

  • The immediate question above is being answered on a separate thread in the modeling forum.

    Thank you,

    Adam

  • HI Adam,

    thanks a lot

    thanks

  • Louis,

    1) the triangles are equilateral and all sides are 0.25mm.
    2) A = the distance from the centroid to the base of the triangle is 0.072mm

    I measured the below distances roughly off of the .dxf file.   

    B= 0.23mm
    C= 0.25mm

    Thank you,
    Adam

  • Hi Adam,

    because our cad team want to double check symbol size
    thanks for your help
