Notes
1. 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 switching outputs;
∑ (CL × VCC2 × fo) = sum of outputs.
2. For 74HC2G86 the condition is VI = GND to VCC.
For 74HCT2G86 the condition is VI = GND to VCC − 1.5 V.
