[1] Typical values are measured at nominal supply voltage (VCC = 3.3 V and VCC = 5.0 V).
[2] tpd is the same as tPLH and tPHL; Cext = 0 pF; Rext = 5 k.
[3] For Cext 10 nF, the typical value of the pulse width tW (s) = Cext (nF) Rext (k).
[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 V.
[5] Cext has no limits.
