VALUE UNIT
V(ESD) Electrostatic discharge Human-body model (HBM), per AEC Q100-002(1) All pins ±2000 V
Pins IN0-IN23(2) ±4000
Charged-device model (CDM), per AEC Q100-011 All pins ±500
Corner pins (pin 1, 19, 20 and 38) ±750
Contact discharge, un-powered, per ISO- 10605:
  • External components: capacitor = 15 nF; resistor = 10 Ω
  • ESD generator parameters: storage capacitance = 150 pF; discharge resistance = 330 Ω or 2000 Ω
 Pins IN0-IN23 ±8000
Contact discharge, powered-up, per ISO- 10605:
  • External components: capacitor = 15 nF; resistor = 33 Ω
  • ESD generator parameters: storage capacitance = 150 pF or 330pF; discharge resistance = 330 Ω or 2000 Ω
 Pins IN0-IN23 ±8000
(1) AEC Q100-002 indicates that HBM stressing shall be in accordance with the ANSI/ESDA/JEDEC JS-001 specification.
(2) ±4-kV rating on pins IN0-IN23 are stressed with respect to GND (with AGND, DGND, and EP tied together).
