CD4051B: power calculation of CMOS multiplexer

Deeksha R

Part Number: CD4051B

Hi, 

what is the supply current of the part CD4051BPWR.

Can you please tell value of Cpd (power dissipation capacitance) and also how to calculate the power or dynamic power of this part?

    Hey Deeksha,

    The supply current is in the datasheet : 

    As for the Cpd, it's a little more complicated and may require some digging into on my end to see if we have that data stored somewhere but typically you'll use the cpd for the dynamic power calculation. I'll update you on what I can find

    Thanks,
    Rami
