Notes
1. CPD is used to determine the dynamic power dissipation (PD in mW): PD = CPD ´ VCC2 ´ fi + å (CL ´ VCC2 ´ fo) where:
fi = input frequency in MHz
fo = output frequency in MHz
å (CL ´ VCC2 ´ fo) = sum of outputs
CL = output load capacitance in pF
VCC = supply voltage in V
2.For HC the condition is VI = GND to VCC
For HCT the condition is VI = GND to VCC - 1.5 V
