[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 tPLH and tPHL.
[3] ten is the same as tPZL and tPZH.
[4] tdis is the same as tPLZ and tPHZ.
[5] CPD is used to determine the dynamic power dissipation (PD in μW).
PD = CPD × VCC2 × fi × N + ∑ (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 = total load switching outputs;
∑(CL × VCC2 × fo) = sum of outputs.
