SN74AHC244-EP: Thermal Resistivity from junction to case Needed

Robert Seabrook

Part Number: SN74AHC244-EP

Hi,

I am looking for the theta_jc value for this part. I was unable to find it in my current datasheet.

Thank you!

Hi Robert,

Do you need this value for the PW (TSSOP) or the DW (SOIC) package? Once I know I can request this information for you.

PW package please. Thank you

Hi Robert,

The request has been submitted. There is usually a 2 week turnaround for these. I will update this post once I receive the information.
