SN54HC595: ThetaJC information

Andrea Bordonali

Part Number: SN54HC595

Tool/software:

I am looking for the thermal rise for this component in package J, which is a 16 CDIP. Is the thermal resistance from junction to top of case and/or bottom case available? The datasheet lists junction to ambient, but my application is for space.

Thanks,

Andrea

Hi Andrea,

I will have to submit a thermal request ticket to get this information. This has a lead time of 2 weeks.
