SN74LVC8T245: Junction temperature and power dissipation of SN74LVC8T245

Hello Prasanna,

To find TJMax, you can use the following calculations:

TJMax = TA + ( R θJA × PD )

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

R θJA = junction to ambient thermal resistance ( °C / W ) (see datasheet for the value for your package)

PD = power dissipation in package (W)

For estimating the power dissipation, please refer to the following document "CMOS Power Consumption and Cpd Calculation":
