Absolute Maximum Ratings Thermal Information Operating Conditions Thermal Resistance (Typical, Note 2) θJA (oC/W) CAUTION: Stresses above those listed in “Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress only rating and operatio no ft h e device at these or any other conditions above those indicated in the operational sections of this specification is not implied. NOTES: 1. Short circuit may be applied to ground or to either supply. Temperatures and/or supply voltages must be limited to keep dissipation within max- imum rating. 2. θJA is measured with the component mounted on an evaluation PC board in free air.
