Hello,
We are considering the SN65LBC184 and the SN65HVD08 for a design, and need some help with the differences between the two with respect to the failsafe biasing during idle conditions. We notice that the SN65LBC185 gives a larger difference between channel A and channel B during idle. The SN65HVD08 has both A and B at similar potential which is causing crosstalk issues, which is causing the Vid to be < -200mV when idle.
We have no fail safe biasing on the board, and would like to use SN65LBC184 instead, because the difference when idle is great enough that we don't see crosstalk. Speed is not an issue as my interface is 19.2k Baud. Can you please provide me with an explanation as to why SN65LBC184 is showing this result? Also can you point me in the right direction of additional transceivers that will give me similar result as the SN65LBC184?
Thanks
