[1] Typical values are measured at Tamb = 25 °C

Typical values for VCC = 2.3 V to 2.7 V are measured at VCC = 2.5 V

Typical values for VCC = 3.0 V to 3.6 V are measured at VCC = 3.3 V

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

ten is the same as tPZH and tPZL;

tdis is the same as tPHZ and tPLZ.

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

PD = CPD x VCC2 x fi x N + ∑(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;

∑(CL x VCC2 x fo) = sum of outputs.
