Z-Suffix −65°C to +175°C P-Suffix, S-Suffix −65°C to +150°C Lead Temperature (Soldering, 60 sec) 300°C 1 For supply voltages less than ±20 V, the absolute maximum input voltage is equal to the supply voltage. Stresses above those listed under Absolute Maximum Ratings may cause permanent damage to the device. This is a stress rating only; functional operation of the device at these or any other conditions above those indicated in the operational section of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.
