What is the Theta JC for the SN74ALVC244IPWREP? I am interested in this value to calculate the temperature rise from the junction to the board.

Wade,
Theta JC (bottom) is probably not the right way to express what I'm looking for. I am trying to calculate Theta JB and have been calculating the resistance from the leads using the material and the drawing information. Therefore what I am really looking for is a Theta junction-to-lead; although, a Theta JB would be more useful if available.
The plan is to not use thermal pads or paste unless it is needed. The hope is that the calculations will show that it is not needed.
Please let me know if additional information is needed.
Thank you,
Mike
Oddly enough, this completed just this morning. I apologize, it was delayed because I did not get it submitted correctly.
Here is the data.
Theta JA-High K 97.9
Theta JC, top 38.5
Theta JB 49.5
Psi JT 4.2
Psi JB 49.1
Regards,
Wade
