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

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

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

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

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

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

PD = CPD x VCC 2 x fi x N + Σ(CL x VCC 2 x 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

Σ(CL x VCC 2 x fo) = sum of the outputs
