SN74LV4040A-EP: Thermal information

Part Number: SN74LV4040A-EP

Hi Team,

I am looking for the thermal information of this part SN74LV4040A-EP. I checked the datasheet and I was unable to find information. (it points me to a broken link) .

I am specifically looking for "the thermal junction to ambient resistance and thermal junction to case resistance " or " the thermal case to ambient resistance"

 Can you help? Thanks in advance.

Regards,

Marvin

  • Hi Marvin,

    We do not have that information on file. I'll go ahead and submit a request for this data. It'll take typically 2 weeks to complete and then I'll post the results here. 

    Regards,
