74LVC3G07

Triple buffer with open-drain output

[1]

All typical values are measured at nominal VCC and Tamb = 25 °C.

[2]

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

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

fi = input frequency in MHz;

fo = output frequency in MHz;

CL = output load capacitance in pF;

VCC = supply voltage in Volts;

N = number of inputs switching;

∑(C

L × VCC

× f

o) = sum of outputs.

The condition is VI = GND to VCC.
