[1] All typical values are measured at Tamb = 25 °C.

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

ten is the same as tPZL and tPZH.

tdis is the same as tPLZ and tPHZ.

[3] Typical values are measured at nominal supply voltage (VCC = 3.3 V).

[4] 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.
