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

VDD Typical formula
where:
PD
dynamic power dissipation 5 V PD = 450 fi + (fo CL) VDD2 (W) fi = input frequency in MHz;
10 V
15 V
PD = 2900 fi + (fo CL) VDD2 (W)
PD = 11700 fi + (fo CL) VDD2 (W)
fo = output frequency in MHz;
CL = output load capacitance in pF;
(fo CL) = sum of the outputs;
VDD = supply voltage in V.
