[1] Typical values are measured at Tamb = 25 °C and VCC = 1.8 V, 2.5 V, 2.7 V and 3.3 V respectively.

[2] tpd is the same as tPHL and tPLH.

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

PD = CPD × VCC2 × fi × N + Σ(CL × VCC2 × fo) where:

fi = input frequency in MHz

fo = output frequency in MHz

CL = output load capacitance in pF

VCC = supply voltage in Volts

N = number of inputs switching

Σ(CL × VCC2 × fo) = sum of the outputs
