6.2 ESD Ratings
V_(ESD) Electrostatic discharge
Human-body model (HBM), per ANSI/ESDA/JEDEC JS-001⁽¹⁾
Charged-device model (CDM), per JEDEC specification JESD22-
C101 ⁽²⁾
VALUE
±2000
±1500
(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.

(1) All currents into device pins are shown as positive values; all currents out of the device are shown as negative; all voltages are
referenced to ground unless otherwise specified. All values shown as max or min are classified on absolute value basis.
(2) All typical values are V_CC = 5 V, T_A = 25°C.
(3) Only one output at a time should be shorted.
