Hello evrbd,

I want to know the footprint for buffer 74LS244 and capacitor 470uF.

One more thing, when I add the footprint TO218AC for TIP140 and TIP 145, the following error message displayed. "Electrical Package TIP147 for comp Q1 has at least one pin(0) which has no corresponding pin on footprint TO218AC"

What I should do?


Thank you.

Best Regards,
Shereen

You can start by being more specific, for example what kind of tool you are using?!!
