11. Dynamic characteristics
[1]
tpd is the same as tPLH and tPHL.
[2]
Typical values are measured at VCC = 3.3 V.
[3]
Typical values are measured at VCC = 5.0 V.
[4]
CPD is used to determine the dynamic power dissipation PD (µW).
PD =CPD × VCC2 × fi + ∑ (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

supply current VI =VCC or GND; IO = 0 A;
VCC = 5.5 V
