Exposure to such conditions may adversely impact product reliability and result in failures not covered by warranty. NOTES: 4. θJA is measured with the component mounted on a low effective thermal conductivity test board in free air. See Tech Brief TB379 for details. 5. For θJC, the “case temp” location is taken at the package top center. Electrical Specifications VDD = 3.3V, VSS = 0V, TA = +25°C, Unless Otherwise Specified.
