[1] All typical values are measured at Tamb = 25 C.
[2] tpd is the same as tPLH and tPHL.
[3] Typical values are measured at nominal supply voltage (VCC = 3.3 V).
[4] 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
(CL VCC2 fo) = sum of the outputs.
