... GND. V+ and V- drive the internal CMOS switches and set their analog voltage limits, so there are no connections between the analog signal path and GND. Unlike switches with a 13V maximum supply voltage, the ISL43840 15V maximum supply voltage provides plenty of room for the 10% tolerance of 12V supplies ( as well as room for overshoot and noise spikes ...

The difference in the two diode leakages to the V+ and V- pins constitutes the analog-signal- path leakage current. All analog leakage current flows between each pin and one of the supply terminals, not to the other switch terminal ...
