TCA9617B: input signal noise tolerance margin

Part Number: TCA9617B

Hi Team,

What's the input noise tolerance margin of TCA9617? 

My customer found there will be a ringing noise add on the input high signal.  

     Ringing signal period of occurrence is around 1MHz, duration time about 38ns,Pk to Pk amplitude 0.8V.   VCC is 3.3V.  

     Please help check if this period noise will cause I2C signal abnormal when translation?   Thank you.
