6.2 ESD Ratings

VALUEUNIT
V(ESD)Electrostatic dischargeHuman body model (HBM), per ANSI/ESDA/JEDEC JS-001, all pins(1)±2000V
Charged device model (CDM), per JEDEC specification JESD22-C101, all pins(2)±500
(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.
