*1: For operation in conditions where Ta > +25°C, the SOP version should be derated by 7.4 mW/°C, and the DIP
version should be derated by 11.1 mW/°C.
*2: When mounted on a 4 cm-square dual-sided epoxy board.
Note: Permanent device damage may occur if the above Absolute Maximum Ratings are exceeded. Functional
operation should be restricted to the conditions as detailed in the operational sections of this data sheet.
Exposure to absolute maximum rating conditions for extended periods may affect device reliability.
