16. Application information
The slow input rise and fall times cause additional power dissipation, this can be
calculated using the following formula:
Padd = fi × (tr × ∆ICC(AV) + tf × ∆ICC(AV)) × VCC where:
Padd = additional power dissipation (µW);
fi = input frequency (MHz);
tr = input rise time (ns); 10 % to 90 %;
tf = input fall time (ns); 90 % to 10 %;
∆ICC(AV) = average additional supply current (µA).
∆ICC(AV) differs with positive or negative input transitions, as shown in Figure 11 and
Figure 12.
