SN74LVT16244B: Could you please help double check the risks of the negative -450mv?

Part Number: SN74LVT16244B
Other Parts Discussed in Thread: TINA-TI

Hi Team,

 

My customer is using the SN74LVT16244B now. The system block is as below.

 

TP1: green

TP2:blue

TP3: yellow

TP2-TP1: brown

 

From the waveform and setting, the CPLD output current is 12mA, TP3 max negative voltage is -450mv(within 5ns), we want to check whether it has risks here.

 

In my opinion, it should be fine. (3.3+0.45)/4.7+12mA<50mA. Could you please help double check it? Thanks.
