6.1 Absolute Maximum Ratings

See(1)
MIN MAX UNIT
VCC Supply voltage –0.5 6.5 V
VI Input voltage (2) –0.5 6.5 V
VO Voltage range applied to any output in the high-impedance or power-off state(2) –0.5 6.5 V
VO Voltage range applied to any output in the high or low state(2)(3) –0.5 VCC + 0.5 V
IIK Input clamp current VI < 0 –50 mA
IOK Output clamp current VO < 0 –50 mA
IO Continuous output current ±50 mA

(1) Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under Recommended Operating Conditions is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
(2) The input negative-voltage and output voltage ratings may be exceeded if the input and output clamp-current ratings are observed.
(3) The value of VCC is provided in the Recommended Operating Conditions table.

6.2 ESD Ratings

VALUE UNIT
V(ESD) Electrostatic discharge Human body model (HBM), per ANSI/ESDA/JEDEC JS-001(1) 2000 V
Charged device model (CDM), per JEDEC specification JESD22-C101(2) 1000
(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.
