 tpd is the same as tPLH and tPHL.
ten is the same as tPZL and tPZH.
tdis is the same as tPLZ and tPHZ.
 Typical values are measured at VCC = 3.3 V.
 Typical values are measured at VCC = 5.0 V.
 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.
Measurement points are given in Table 9.
Logic levels: VOL and VOH are typical output voltage levels that occur with the output load.
