I wonder if someone is able to implement ADM3251E successfully. I am using single isolated RS 232 channel, but each time I connect the RS232 cable to my computer. The signal on the logic side can be changed a few hundred millivolts, a few hundred millivolts are too much for my application. It can changed my logic from True to False. The datasheet said the chip is fully isolated with 2.5kV, I wonder it should be nothing changed on the logic side as I connected the RS232 cable. Thank you so much.
