[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.
[3] ten is the same as tPZH and tPZL.
[4] tdis is the same as tPHZ and tPLZ.
[5] 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
