[1] All typical values are measured at Tamb = 25 °C.
[2] tpd is the same as tPLH and tPHL.
[3] Typical values are measured at nominal supply voltage (VCC = 3.3 V and VCC = 5.0 V).
[4] CPD is used to determine the dynamic power dissipation (PD in µW).
PD = CPD × VCC2 × fi × N + Σ(CL × VCC2 × 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
Σ(CL × VCC2 × fo) = sum of the outputs.
