Hi All
I have analog switch in my board, when i do ESD diode check the value i am getting is around .3 to .4v for NXP switch(even this is decreasing when i hold it for some time).
What would be the reason would be.
Maybe a big diode, maybe a Schottky diode, maybe your test
conditions and limits are all made up by you irrespective of
the realities of the product design, maybe there is a shunt
elsewhere on the trace.

You say the switch is in your board. That implies that there
are connections to it. Those connections might affect the
readings - for example, maybe somebody put Schottky clamps
at the input connector the switch connects to (or something).
