Notes
1. CPD is used to determine the dynamic power dissipation (PD in µW).
PD = CPD Ã VCC2 Ã fi + â (CL Ã VCC2 Ã fo) where:
fi = input frequency in MHz;
fo = output frequency in MHz;
CL = output load capacitance in pF;
VCC = supply voltage in Volts;
â (CL Ã VCC2 Ã fo) = sum of outputs.
2. For HC1G the condition is VI = GND to VCC.
For HCT1G the condition is VI = GND to VCC â 1.5 V.
