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