Zener diodes fabricated in a proprietary silicon avalanche
technology protect each I/O pin to provide a high level of
protection for electronic equipment that may experience
destructive electrostatic discharges (ESD). These robust
diodes can safely absorb repetitive ESD strikes above
the maximum level specified in the IEC 61000-4-2
international standard (Level 4, ±8kV contact discharge)
without performance degradation.
