Product data sheet
The slow input rise and fall times cause additional power dissipation, this can be
calculated using the following formula:
P_ad = f_i × (t_r × I_CC(AV) + t_f × I_CC(AV)) × V_CC where:
P_ad = additional power dissipation (µW);
f_i = input frequency (MHz);
t_r = input rise time (ns); 10 % to 90 %;
t_f = input fall time (ns); 90 % to 10 %;
I_CC(AV) = average additional supply current (µA).
