[1] Typical values are measured at nominal VCC and at Tamb = 25 C.

[2] tpd is the same as tPLH and tPHL

[3] CPD is used to determine the dynamic power dissipation (PD in W).

PD = CPD  VCC2  fi  N + (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;

N = number of inputs switching;

(CL  VCC2  fo) = sum of outputs.
