SN74AHC74PWR resistance junction to board

Good morning, would be possible to know the value of the resistance junction to board of the following part numbers: 

- SN74AHC74PWR


I was not able to find it in the datasheet.
Thank you.

Kind regards,

  • Hi Claudio,

    I apologize the wait, but I have already put in a request for this information and the expected time to hear back is 2 weeks. It has only been a few days, but I will check with the people in charge of this request and see if we can get this back sooner. 

    We appreciate your patience. I will close this thread for now and respond back with the results on your original question.
