(GND – 0.3V) to (VDD + 0.3V) Package Thermal Resistance: PDIP (RθJA).............................................125°C/W SOIC (RθJA) ............................................155°C/W MSOP (RθJA) ..........................................200°C/W Specified Temperature Range ........... -40°C to +125°C Storage Temperature Range.............. -65°C to +150°C *Stresses above those listed under "Absolute Maximum Rat- ings" may cause permanent damage to the device. These are stress ratings only and functional operation of the device at these or any other conditions above those indicated in the operation sections of the specifications is not implied. Expo- sure to absolute maximum rating conditions for extended peri- ods may affect device reliability.
