The datasheet for the DS16F95WQML RS422 transceiver states that the maximum receiver input voltage is +15V. I am investigating a possible failure mode in a circuit I am designing and would like to know what the behavior of this chip would be if, say, 28V were present at the receiver inputs. Would the failure mode be limited to just the receiver, or would it propagate through the part to other circuits around/behind the transceiver? I would like to get more information on the internal configuration of this chip so that I can make an assessment regarding this question.
