LF25x, LF356B, LF35x 220 Storage temperature, Tstg −65 150 °C (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) The maximum power dissipation for these devices must be derated at elevated temperatures and is dictated by TJMAX, θJA, and the ambient temperature, TA. The maximum available power dissipation at any temperature is PD = (TJMAX − TA) / θJA or the 25°C PdMAX, whichever is less. (3) If Military/Aerospace specified devices are required, contact the TI Sales Office/Distributors for availability and specifications. (4) Unless otherwise specified the absolute maximum negative input voltage is equal to the negative power supply voltage.
6.2 ESD Ratings VALUE UNIT
V(ESD) Electrostatic discharge Human body model (HBM), per ANSI/ESDA/JEDEC JS-001(1)(2) ±1000 V (1) JEDEC document JEP155 states that 500-V HBM allows safe manufacturing with a standard ESD control process. (2) 100 pF discharged through 1.5-kΩ resistor
