Triple 2-channel analog multiplexer/demultiplexer

[1]

tpd is the same as tPHL and tPLH.

[2]

ton is the same as tPZH and tPZL.

[3]

toff is the same as tPHZ and tPLZ.

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

PD = CPD  VCC2  fi  N + {(CL +Csw)  VCC2  fo} where:

fi = input frequency in MHz;

fo = output frequency in MHz;

N = number of inputs switching;

{(C

L +Csw)  VCC

 f

o} = sum of outputs;

CL = output load capacitance in pF;

Csw = switch capacitance in pF;

VCC = supply voltage in V.
