Dynamic characteristics [1] Typical values are measured at Tamb =25 C and VCC = 1.8 V, 2.5 V, 2.7 V, 3.3 V and 5.0 V respectively. [2] tpd is the same as tPLH and tPHL. [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 Volts; N = number of inputs switching; (C L VCC 2 f o) = sum of the outputs.
