Applying a voltage source to this pin externally may cause irreversible damage. Stresses at or above those listed under Absolute Maximum Ratings may cause permanent damage to the product. This is a stress rating only; functional operation of the product at these or any other conditions above those indicated in the operational section of this specification is not implied. Operation beyond the maximum operating conditions for extended periods may affect product reliability. THERMAL CHARACTERISTICS θJA is specified for the worst-case conditions, that is, a device soldered in a circuit board for surface-mount packages. Table 7. Thermal Resistance Package Type θJA Unit 32-Lead LFCSP (CP-32-13) 32.5 °C/W ESD CAUTION Rev. A | Page 10 of 61 |
