Hi Team,
This is Brandon, My customer is using the SN65176B as RS485 and during the test, we found there are overshoot and undershoot voltage on D-pin, the waveform is attached below:
From the waveform, we found that the undershoot voltage below to -0.62V and overshoot voltage reach to 5.9v. From the datasheet, we could only found the recommendation below:
could you help check is there any Tolerance on this pins? and also how could we enhance DI siganl quality?
