minimum value of on resistance as measured over the specified
analog signal range.
Crosstalk
A measure of unwanted signal that is coupled through from one
channel to another because of parasitic capacitance.
IS (OFF)
Source leakage current with the switch off.
ID (OFF)
Drain leakage current with the switch off.
ID, IS (ON)
Channel leakage current with the switch on.
