[1] Typical values are measured at Tamb = 25 °C.

Typical values are measured at VCC = 1.8 V for VCC = 1.65 V to 1.95 V.

Typical values are measured at VCC = 2.5 V for VCC = 2.3 V to 2.7 V.

Typical values are measured at VCC = 3.3 V for VCC = 3.0 V to 3.6 V

[2] tpd is the same as tPHL and tPLH.

[3] CPD is used to determine the dynamic power dissipation PD = CPD x VCC 2 x fi x N + Σ (CL x VCC 2 x fo), where:

PD in μW

fi = input frequency in MHz;

fo = output frequency in MHz;

N = total load switching outputs

Σ (CL x VCC 2 x fo) = sum of outputs;

CL = output load capacitance in pF;

VCC = supply voltage in V.
