Why does the ADG884 switch get stuck at a certain voltage when the input
voltage exceeds the maximum


Under or overvoltage spikes can trigger parasitics in the part that cause
new paths to be created in the silicon, which may create a resistor to Vdd
which pulls the output to a certain voltage. Once power is removed these
parasitics go away, resetting the device.
