Need land pattern for HTSSOP 32 for TLC5947DAP

Hello Rick,

In general if you are searching for CAD data, you can find HTSSOP package CAD data in the TLC5924 folder which uses the same package.

Here attached you can find the package drawing:

5700.DAP_outline.pdf

and the PowerPad dimensions:

6242.TLC5947_ThermalPad.pdf

For the right dimensioning of the mask opening and the amount of vias, please have a look to the application note: http://www.ti.com/litv/pdf/slma002g

For DAP 32 pins, the recommended mask opening size is 5.2mm * 11mm with 3*6 vias (Figure 10, page 9).

Best regards,
Brigitte
