[1] All typical values are measured at Tamb = 25 C.
[2] tpd is the same as tPLH and tPHL.
ten is the same as tPZL and tPZH.
tdis is the same as tPLZ and tPHZ.
[3] Typical values are measured at VCC = 2.5 V.
[4] Typical values are measured at VCC = 3.3 V.
[5] 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;
(CL VCC2 fo) = sum of the outputs.
