[1] Typical value of the propagation delay and output transition time can be calculated with the extrapolation formula (CL in pF).

VSS = 0 V; tr = tf 20 ns; Tamb = 25 C.
Symbol Parameter
VDD Typical formula
PD
dynamic power
5 V PD = 1300 fi + (fo CL) VDD2 (W)
dissipation
10 V PD = 6400 fi + (fo CL) VDD2 (W)
15 V PD = 18700 fi + (fo CL) VDD2 (W)
where:
fi = input frequency in MHz;
fo = output frequency in MHz;
CL = output load capacitance in pF;
(fo CL) = sum of the outputs;
VDD = supply voltage in V.
