Dynamic characteristics [1] tpd is the same as tPLH and tPHL [2] tt is the same as tTLH and tTHL [3] CPD is used to determine the dynamic power dissipation (PD in W). PD =CPD VCC2 fi N+ (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; (C L VCC 2 f o) = sum of the outputs. Table 9. Dynamic characteristics Voltages are referenced to GND (ground = 0 V); for test circuit see Figure 11.
