o calculate worst case power dissipation into the load, use the following equations which assume a 50 load.
Pd_H is power dissipation when the output drives high.
Pd_L is the power dissipation when the output drives low.
Pd_H = (V

Pd_H = (1.0V/50 ) * (3.465V - 1.0V) = 49.3mW
Pd_L = (0.4V (50 ) * (3.465V - 0.4V) = 24.52mW
Total Power Dissipation per output pair = Pd_H + Pd_L = 73.82mW
