SN65HVD75: There is spike from low to high on the RX line when the RE switch from high to low

Part Number: SN65HVD75

Hello team,

I am using SN65HVD75 for RS485 communication. I found on the Rx line there would be a spike about 500ns if the RE pin switched from high to low. Is there a way to get rid of it?

Thank you.

Kind regards

Dazhuang,

Can you give some detail about the setup? I assume the blue line is REB pin and yellow is R. Is REB connected to DE as well? What's the status of D? How about the condition of bus and R? Thanks,

Hao
