[1] tpd is the same as tPLH and tPHL.

ten is the same as tPZL and tPZH.

tdis is the same as tPLZ and tPHZ.

[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 (W).

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.
