[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.

[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 x VCC 2 x fi x N + Σ(CL x VCC 2 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 VCC 2 x fo) = sum of outputs
