5.2 ESD Ratings

POS VALUE UNIT
2.1 V(ESD) Electrostatic discharge, Human Body Model Human body model (HBM), per ANSI/ESDA/JEDEC JS-001, all pins(1) ±2000 V
2.2 V(ESD) Electrostatic discharge, Charged Device Model Charged device model (CDM), per ANSI/ESDA/JEDEC JS-002, all pins(2)   ±500 V
(1) JEDEC document JEP155 states that 500-V HBM allows safe manufacturing with a standard ESD control process.
(2) JEDEC document JEP157 states that 250-V CDM allows safe manufacturing with a standard ESD control process.
