(1)

Short circuits from outputs to VCC can cause excessive heating and eventual destruction.

(2)

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.

(3)

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.
