Table 12. Dynamic power dissipation PD
PD can be calculated from the formulas shown; VEE = VSS = 0 V; tr = tf ï£ 20 ns; Tamb = 25 ï°C.
Symbol Parameter
VDD
Typical formula for PD (ïW)
where:
PD
dynamic power 5 V
PD = 1300 ï´ fi + ï(fo ï´ CL) ï´ VDD2
fi = input frequency in MHz;
dissipation
10 V
PD = 6100 ï´ fi + ï(fo ï´ CL) ï´ VDD2
fo = output frequency in MHz;
15 V
PD = 15600 ï´ fi + ï(fo ï´ CL) ï´ VDD2
CL = output load capacitance in pF;
VDD = supply voltage in V;
ï(CL ï´ fo) = sum of the outputs.
