Dual supply single buffer and single buffer with open-drain

[1]

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

[2]

Power dissipated from input supply (VCCI)

PD =CPD  VCCI2  fi  N where:

CPD = power dissipation capacitance of the input supply.

VCCI = input supply voltage in V;

fi = input frequency in MHz;

N = number of inputs switching;

[3]

Power dissipated from output supply (VCCO)

PD =(CL + CPD)  VCCO2  fo where:

CL = load capacitance in pF;

CPD = power dissipation capacitance of the output supply.

VCCO = output supply voltage in V;

fo = output frequency in MHz;

Table 13.

Typical dynamic characteristics at Tamb = 25 C

Voltages are referenced to GND (ground = 0 V); for test circuit see Figure 12; for wave form see Figure 5.
