Dynamic current of IO = Σ IO (Cin + Cload) × IO switching frequency × Voltage

= ((8 pF × 8) × 10 MHz + (30 pF × 8) × 10 MHz) × 3.5 V

= 10.6 mA

Total power consumption

= Voltage × (Leakage current + Dynamic current)

= (40 mA × 3.5 V) + (36.6 mA + 10.6 mA) × 3.5 V

= 305 mW (0.305 W)

Tj = Ta + θja × Total power consumption

= 100 °C + 41.3 °C/W × 0.305 W

= 112.6 °C
