SN54ACT00: ThetaJC information

Andrea Bordonali

Part Number: SN54ACT00

Tool/software:

For the CDIP package, I am looking for thermal rise information between the junction and bottom case. Is this information available?

Hi Andrea,

We don't currently have that information. I can submit for a new thermal model to be built to provide that information, but it will take a few weeks.

Best,

Ian
