tpd is the same as tPHL and tPLH.

ten is the same as tPZH and tPZL.

[3]

tdis is the same as tPHZ and tPLZ.

[4]

tt is the same as tTHL and tTLH.

[5]

CPD is used to determine the dynamic power dissipation (PD in µW).

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;

∑(C

L × VCC

× f

o) = sum of outputs.
