[1] Typical values are measured at Tamb = 25 °C and VCC = 1.2 V, 1.8 V, 2.5 V, 2.7 V, and 3.3 V respectively.

[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] Skew between any two outputs of the same package switching in the same direction. This parameter is guaranteed by design.

[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.
