Other Parts Discussed in Thread: SN65176B
Dear Sirs
I use SN65176B like the following figure. ( figure 1)
Left SN65176B is setting for receiver. Right SN65176B is setting for transceiver.
When I disable right SN65176B transceiver (DE disable), the output D+ D- will like the figure 2 (red).
And the Left SN65176B receiver Rx will work NG. figure 2 (green).
If I use SN65HVD485ED(the same circuit), test is ok (figure 3 (green).)
Could you help the issue? Thanks
