74HC3G06; 74HCT3G06

Triple inverter with open-drain outputs

[1]

CPD is used to determine the dynamic power dissipation (PD in µW).

PD = CPD × VCC2 × fi × N + Σ(CL × VCC2 × fo) where:

fi = input frequency in MHz;

fo = output frequency in MHz;

CL = output load capacitance in pF;

VCC = supply voltage in V;

N = number of inputs switching;

Σ(C

L × VCC

× f

o) = sum of outputs.
