Hi There,
Our orginal design uses SN75LBC184D, but the 75 version is now in shortage on market, to fullfill the production demand we bought some SN65LBC184D to use as replacement, as we checked the date sheet 65 verision is a higher level than 75 on function.
But now we encountered some serious problem, when using the SN65LBC184D some of them cannot receive the signal totally or keep receiving wrong signal; while some others even burned themselves. We kept the circuit environment the same.
May I know why and any method to solve it? Thanks a lot!!
