[1] All typical values are measured at Tamb = 25 ï°C.
[2] tpd is the same as tPLH and tPHL.
ten is the same as tPZL and tPZH.
tdis is the same as tPLZ and tPHZ.
[3] CPD is used to determine the dynamic power dissipation PD (ïW).
PD = CPD ï´ VCC2 ï´ fi + ï((CL ï´ CSW) ï´ VCC2 ï´ fo) where:
fi = input frequency in MHz;
fo = output frequency in MHz;
CL = output load capacitance in pF;
CSW = maximum switch capacitance in pF (see Table 7);
VCC = supply voltage in volts;
ï((CL ï´ CSW) ï´ VCC2 ï´ fo) = sum of outputs.
