Hi team,
Does TI have Rtheta,JC(top) of sn74lv138a? It will be used for estimating junction temperature with using Rtherta,JC(top) through testing.

Hi Takeshi,
Yes it does, are you looking for Rtheta,jc(top) in a particular package of SN74LV138A?

Hi Gabriel,
Thank you for your comments. Yes, I need Rtheta,jc(top) of SN74LV138APW, so TSSOP -PW package. Could you provide the value?
Best regards,
Takeshi Sasaki
Hi Takeshi,
I will request the thermal values for the PW package. It can take up to three weeks, typically faster.

Gabriel
Hi Gabriel,
Thank you for your comments. I see. Could you update this thread once you'll get the thermal value? Thanks!
Best regards,
Takeshi Sasaki
