14. Application information
The slow input rise and fall times cause additional power dissipation, which can be
calculated using the following formula:
Padd =f
i(trICC(AV) +t
fICC(AV))VCC where:
Padd = additional power dissipation (W);
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 (A).
ICC(AV) differs with positive or negative input transitions, as shown in Figure 14.
For XC7WH14 used in relaxation oscillator circuit, see Figure 15.
