*For crosstalk this pin is NO2.
NC2 and COM2 are open.
Measurements are standardized against shorts at IC terminals. Off-Isolation is
measured between COM_
and “OFF” NO_ or NC_ terminal on each switch. On-Loss is measured between
COM_ and “ON” NO_ or NC_ terminal on each switch. Crosstalk is measured from
one channel to the other channel. Signal direction through switch is reversed;
worst values are recorded.
