Dynamic characteristics [1] Typical values are measured at nominal VCC and at Tamb =25 °C. [2] tpd is the same as tPLH and tPHL [3] CPD is used to determine the dynamic power dissipation (PD in µW). PD = CPD × VCC2 × fi × N + Σ(CL × VCC2 × fo) where: fi = input frequency in MHz; fo = output frequency in MHz; CL = output load capacitance in pF; VCC = supply voltage in V; N = number of inputs switching; Σ(C L × VCC 2 × f o) = sum of outputs. 12. Waveforms Table 9. Dynamic characteristics Voltages are referenced to GND (ground = 0 V); for load circuit see Figure 13.

VOL and VOH are typical output voltage levels that occur with the output load. Fig 12.
