Junction Temperature Tjmax 150 °C Junction temperature at the storage condition Electrostatic discharge voltage (human body model) VESD -4000 to +4000 V Caution: Operating the IC over the absolute maximum ratings may damage the IC. The damage can either be a short circuit between pins or an open circuit between pins and the internal circuitry. Therefore, it is important to consider circuit protection measures, such as adding a fuse, in case the IC is operated over the absolute maximum ratings. (Note1) Not Recommended for New Designs.
