Attached below is the schematic of how we used it. The SN65HVD230D corrupts CAN line signals, it works again after replacing it with a new one. Multiple of our boards are experiencing the same problem.
^Here's a screenshot of what it looks like after connecting the CAN transceiver. The peaks measure around 1.7 and the troughs measure around -2V
^This is the normal CAN signal. Peak/trough: 2.6/1.5V
Here are some voltage and resistance values on our functional and non-functional boards.
We are not sure what is causing this problem.
