Quad 2-input multiplexer; inverting

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

[2] tt is the same as tTHL and tTLH.

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

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 V;

N = number of inputs switching;



(CL  VCC2  fo) = sum of outputs.

Tamb = 40 C to +125 C
