SN74LVC1G02: Thermal Junction to Case/Board Resistance Values Needed

SN74LVC1G02: Thermal Junction to Case/Board Resistance Values Needed

Tool/software:

Good afternoon,  

I had asked the following questions a few months ago and it has gone unanswered...

I did not see any junction to case or junction to board resistances listed on the datasheets of the following parts:SN74LV1T34DBVRG4, SN74LVC1G02MDCKREP, SN74LVC1G06MDCKREP, SN74LVC1G175DBVT. Does Texas Instruments have these values? Thank you for your time and I look forward to hearing back from you. 

Sincerely,

Christian Lowery

    Hi Christian,

    For SNLV1T34DBVRG4

    Result- Theta JA 238.6
    Result-Theta JC, top  165.7
    Result-Theta JB  139.8
    Result- Psi JT  78.7
    Result- Psi JB  139.0

    For SN74LVC1G02MDCKREP

    We do not have this value at this time

    For SN74LVC1G06MDCKREP

    Result- Theta JA 232.6
    Result-Theta JC, top 143.9
    Result-Theta JB  119.3
    Result- Psi JT 45.8
    Result- Psi JB  119.1

    For SN74LVC1G175DBVT

    Result- Theta JA 224.5
    Result-Theta JC, top  186.2
    Result-Theta JB  73.0
    Result- Psi JT  64.0
    Result- Psi JB  72.4

    We just recently changed our method for acquiring thermal data and the expected lead time for the SN74LVC1G02DCKREP may be affected by this. When I have an update I'll provide it.

    Regards,

    Owen
