Where: Pad = additional power dissipation (W) = input frequency (MHz) fi tr = input rise time (ns); 10% – 90% = input fall time (ns); 10% – 90% tf I CC a = average additional supply current (A) Average I CC adiffers with positive or negative input transitions, as shown in Figure 7. 100 R average I CC (A) 75 C 50 positive-going edge SV00433 Figure 8.
