[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.
