CPD

power dissipation

capacitance

per gate; VI = GND to VCC [2]

[1] Typical values are measured at nominal VCC and at Tamb = 25 °C.

[2] CPD is used to determine the dynamic power dissipation (PD in μW).

PD = CPD × VCC 2 × fi × N + ∑(CL × VCC 2 × fo) where:

fi = input frequency in MHz;

fo = output frequency in MHz;

CL = output load capacitance in pF;

VCC = supply voltage in V;

N = number of inputs switching;

∑(CL × VCC 2 × fo) = sum of outputs.
