SN74GTL1655: Output ringing in the falling edge

Part Number:SN74GTL1655

Hi team,

My customer use the part in the switch. And below is the diagram.

The signal is from the A port to B port.

 And they find the B port signal has a ringing in the falling edge.(show as below).

So please help to answer below questions:

1. What may be the cause for the ringing?

2. Customer tried to increase the 0 ohm resister, but it seems a little improvement, not much. So do you have any suggestion for eliminating the ringing?

Lacey

Thanks a lot!
