SN74AHC244: SN74AHC244PWR Power Rating

Donna Langford
Prodigy 70 points
Part Number: SN74AHC244

Tool/software:

What is the maximum power allowable for the part SN74AHC244PWR?

Is this determined from the maximum temperature of 125C and the thermal resistance from Junction to Ambient or Junction to case?

    Yes. (The maximum ambient temperature is 125 °C; the maximum junction temperature is 150 °C.)

    (But when you stay inside the recommended operating conditions, you will never reach the power dissipation limit.)
