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

[2] tpd is the same as tPLH and tPHL; ten is the same as tPZH and tPZL; tdis is the same as tPLZ and tPHZ.

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

PD = CPD x VCC2 x fi x N + Σ(CL x VCC2 x 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;

Σ(CL x VCC2 x fo) = sum of outputs.
