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

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

[3] Propagation delay is the calculated RC time constant of the typical ON resistance of the switch and the specified capacitance when

driven by an ideal voltage source (zero output impedance).

[4] ten is the same as tPZH and tPZL.

[5] tdis is the same as tPLZ and tPHZ.

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

PD = CPD × VCC 2 × fi × N + Σ{(CL + CS(ON)) × VCC 2 × fo} where:

fi = input frequency in MHz; fo = output frequency in MHz;

CL = output load capacitance in pF;

CS(ON) = maximum ON-state switch capacitance in pF;

VCC = supply voltage in V;

N = number of inputs switching;

Σ{(CL + CS(ON)) × VCC 2 × fo} = sum of the outputs.
