Product data sheet
The slow input rise and fall times cause additional power dissipation, which 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 %;
