AGD706 over voltage and open input

To whom it may concern,

 

We are using the ADG706 multiplexer and have stumbled upon two different cases we can't explain.

 

1. While using a 3.3V supply, when one input received a voltage higher than the supply (7.5V), the output is stuck on a high voltage (5.3V), regardless of whether the output is connected to the problematic input or not.

2. While one input floats, the output is also constant, regardless of the switching state.

 

Is that a normal behavior of the component?

 

Thank you very much in advance,

Eli.
