SN74AUP1G74: Thermal information

Shu-Cheng LIN
Guru 11785 points
Part Number: SN74AUP1G74

Hi Sirs,

Sorry to bother you.

We would like to know 

1. SN74AUP1G74DQER Rjc /Rjb /TC

2. SN74LVC2G125DCUR TC

Could you help it?

Thanks!!

    Hello,
    Today is a TI holiday. We will submit this thermal request when we return to the office. Becuase of the holidays, I would expect the results to take 3 to 4 weeks return after that.

    Hi Shu,

    SN74LVC2G125DCUR thermal values below in oC/W

    Result- Theta JA-High K (standard datasheet value)
    190.1
    Result-Theta JC, top (standard datasheet value)
    69.8
    Result-Theta JB (standard datasheet value)
    38.9
    Result- Psi JT (standard datasheet value)

    Hi Sirs,

    Thanks for your reply.

    Actually we would like to know 

    1. SN74AUP1G74DQER Rjc /Rjb /TC

    2. SN74LVC2G125DCUR TC

    But looks you only share SN74LVC2G125DCUR others thermal values.

    So, could you help us to check again?

    Thanks!!

    Hi Shu-cheng,

    The AUP1G74 thermal is not ready yet, hence I shared SN74LVC2g125DCU device thermals which were ready.
    TC stands for case temperature? We only specify the Tjmax (abs max junction temp) at 150C, beyond which there could be reliability issues.
