APPLICATION NOTE 651
ESD Protection for I/O Ports

Abstract: This application note describes how ESD threatens electronic systems, type of damage inflicted, how
ESD is generated, test methods and waveforms used, human body and machine models for testing, IEC
compliance levels, contact and air discharge. Protection methods are described and Maxim's approach to ESD
protection is detailed. Guidelines are given for selecting ICs with high resistance to ESD. RS-232 I/O ports are
specifically considered.
