Question about ADM3065E

Hi All,

The input signal to A and B pins at start up goes down to about -20V but ADM3065E seems to clamp it to about -11V as attachment.

1) Does ADM3065E has any clamp function inside?

2) If 1) is yes, the value of the negative clamping voltage is lower than -9V which is absolute maximum voltage of both A and B pins. It's still out of spec.  

Should I take measures to fit the input signal to within the absolute maximum voltage (-9V~+14V), or I don't have to do any measure?
