(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) These are the maximum allowed voltages for transient spikes. Absolute maximum DC voltages are lower.
6.2 ESD Ratings
V_(ESD) Electrostatic discharge
Charged device model (CDM), per JEDEC specification JESD22-C101,
all pins⁽¹⁾
VALUE
±1500
(1) JEDEC document JEP157 states that 250-V CDM allows safe manufacturing with a standard ESD control process.
