11. Dynamic characteristics
[1]
All typical values are measured at Tamb =25 °C.
[2]
Typical values are measured at VCC = 2.5 V.
[3]
Typical values are measured at VCC = 3.3 V.
[4]
CPD is used to determine the dynamic power dissipation (PD in W).
PD = CPD × VCC2 × fi × N+ ∑ (CL × VCC2 × fo) where:
fi = input frequency in MHz;
fo = output frequency in MHz;
CL = output load capacitance in pF;
VCC = supply voltage in Volts;
N = total load switching outputs;
∑ (C
L × VCC

× f
o) = sum of outputs.

The condition is VI = GND to VCC.
