(1) Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings
only, which do not imply functional operation of the device at these or any other conditions beyond those indicated under Recommended
Operating Conditions. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
(2) If Military/Aerospace specified devices are required, please contact the Texas Instruments Sales Office/Distributors for availability and
specifications.
(3) May exceed input supply voltage.
(4) When used in dual-supply systems where the output terminal sees loads returned to a negative supply, the output voltage should be
diode-clamped to ground.
7.2 ESD Ratings
V_(ESD) Electrostatic discharge
Human-body model (HBM), per ANSI/ESDA/JEDEC JS-001⁽¹⁾
VALUE
±2500
(1) JEDEC document JEP155 states that 500-V HBM allows safe manufacturing with a standard ESD control process.
