APPLICATION INFORMATION
The slow input rise and fall times cause additional power dissipation,
this can be calculated using the following formula:

differs with positive or negative input transitions, as
shown in Figure 7.
= additional power dissipation ( W)
= input frequency (MHz)
= input rise time (ns); 10% – 90%
= input fall time (ns); 10% – 90%
= average additional supply current ( A)
