How much is the input impedance of this analog switch? The data sheet only talks about the on state losses.

Rahul,

Is this input impedance the series resistance when the device is on? If so, then the ron values in the datasheet correspond to the values you need. If not, can you clarify.

Regards,

Alex

Alexandre,

No. These are active analog switches. They must be having a CMOS input stage. I need the input impedance of the device when seen from the input side with respect to ground. The ON state resistance simply states input to output channel resistance. What is the input to ground impedance ?

I believe you can get input impedance from the Ii spec. this calculates to greater than 1Mohm. So these would be consider high impedance inputs
