(2) Short circuits from outputs to VCC can cause excessive heating and eventual destruction. (3) Maximum power dissipation is a function of TJ(max), RθJA, and TA. The maximum allowable power dissipation at any allowable ambient temperature is PD = (TJ(max) – TA) / RθJA. Operating at the absolute maximum TJ of 150°C can affect reliability. (4) Maximum power dissipation is a function of TJ(max), RθJA, and TC. The maximum allowable power dissipation at any allowable case temperature is PD = (TJ(max) – TC) / RθJC. Operating at the absolute maximum TJ of 150°C can affect reliability.
