Dynamic characteristics [1] Typical values are measured at nominal supply voltage (VCC = 3.3 V and VCC = 5.0 V). [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 Volts N = number of inputs switching Σ(C L × VCC 2 × f o) = sum of the outputs. Table 7. Dynamic characteristics GND = 0 V; For test circuit see Figure 7.
