SN74LVC2G32: Thermal info for SN74LVC2G32DCUR

Part Number: SN74LVC2G32

We are using the SN74LVC2G32DCUR on several boards in an enclosure we are doing thermal analysis on and need to know some more information that is not in the datasheet.  We want to make sure we aren't overstressing the part so we need to know the thermal resistance from the device junction to the board, to the case top and to the case bottom.  Only resistance from the junction to ambient is listed in the datasheet.

  • Hi Art,

    We don't have this data on hand. I've submitted a Request and we will have the results in about 2 weeks.

    Regards,

    Owen

  • Hi Art,

    The request took longer than expected. See below for those values.

    Result- Theta JA-High K (standard datasheet value) 222.7
    Result-Theta JC, top (standard datasheet value) 79.9
    Result-Theta JB (standard datasheet value) 132.6
    Result- Psi JT (standard datasheet value) 22.0
    Result- Psi JB (standard datasheet value) 131.8

    Regards,
