Hi

Please tell us the thermal resistance of SN74LVC8T245PW

Tj= ? (security range)

Tc= ? (security range)

Θjc= ?

Best regards

    Hi TI Team,

    I am looking for Junction Temperature Max (Tj Max) info for the following device as well.

    SN74AVC2T245RSWR

    SN74AVC4T245RSVR

    Can TI Team help advise? Thanks.

    Hi

    Please refer the below data.

    Theta JA-High K

      90.6 

    Theta JC,   

       27.6

    Theta JB

      45.3

    Psi JT

        1.3

    Psi JB  

        44.8

     

    The maximum junction temperature is not on hand. Could you let customer to estimate the value by following equation:

     

    TJ = TA + ( R θJA × PD )

    where: TA = ambient temperature for the package ( °C )

    R θJA = junction to ambient thermal resistance ( °C / W )

    PD = power dissipation in package (W)

    Thanks
