In order to identify the source and type of EOS, a number of DS14C88 and DS14C89A devices were subjected to controlled Electrostatic Discharge - ESD (Electrostatic Discharge) events in the lab using a KeyTek Human Body ESD Simulator. Additional units were tested with PolyClamp ESD protection devices to determine their effectiveness and to demonstrate a possible solution for providing greater system ESD tolerance.
