How many nodes can TJA1050T/CM,118 carry? With more than 50 nodes, the high level CANH is a little low. How could I solve this problem? Thank you.

CANH typical value is 3.5V, but when code number bigger than 50, CANH is below 3V. The same thing when baud rate at 20k.

Is it possible to be caused by too many protective devices, because some devices have large capacities. Thank you!

You can try to test without ESD protection components.
