SN74LVC1G11-EP: Thermal Resistance

Namita Pawar
Intellectual 600 points
Part Number: SN74LVC1G11-EP

Hi,

I am using SN74LVC1G11MDCKREP gate in my design. I need junction to case resistance information for the IC.

From datasheet I got junction to ambient resistance. Is there any information available on thermal resistance for IC on TI site?

Thanks,

Namita

    Hi Namita,

    Some of these parts aren't ours (Logic and Voltage Translation). I recommend to go ask the respective groups for those. I can provide you with the data values for our devices.
