ULN2003A: Pattern layout recommendation for ULN2003AN

Part Number: ULN2003A

Hi team

I received below question from my customer. could you please let us know your recommendation?

Do you have any recommendation size when we mount on the board? 

Also I know we have layout example in the datasheet. If you have more specific information to mount, please let us know

thanks

Iza

  • Hi Iza, 

    Apologies, but I am unclear of your question. 

    Are you referring to the width of the routing on the pins? This is going to be limited by your PCB fabrication site. 

    Because pins 1-7 are signal paths, we recommend for those to be thin, whereas pins 8-16 will be high current paths, especially ground, so we recommend those to have a greater routing width. We do not supply any specifics as how thin/thick you can go will depend on the tolerance capacity of your PCB vendor. 

    Best Regards,
