Hex non-inverting buffers

Table 8. Dynamic power dissipation PD

PD can be calculated from the formulas shown. VSS = 0 V; tr = tf  20 ns; Tamb = 25 C.

Symbol Parameter

VDD

Typical formula for PD (W)

where:

PD

dynamic power 5 V

PD = 3800  fi + (fo  CL)  VDD2

fi = input frequency in MHz,

dissipation

10 V

PD = 11600  fi + (fo  CL)  VDD2

fo = output frequency in MHz,

15 V

PD = 65900  fi + (fo  CL)  VDD2

CL = output load capacitance in pF,

VDD = supply voltage in V,

(fo  CL) = sum of the outputs.
