QUICK REFERENCE DATA
GND = 0 V; Tamb =25 °C; tr =tf ≤ 3.0 ns.
Notes
1. CPD is used to determine the dynamic power dissipation (PD in W).
PD =CPD × VCC2 × fi + ∑ (CL × VCC2 × fo) where:
fi = input frequency in MHz;
fo = output frequency in MHz;
∑ (CL × VCC2 × fo) = sum of outputs;
CL = output load capacitance in pF;
VCC = supply voltage in Volts.
2. The condition is VI = GND to VCC.
