CAUTION: Do not operate at or near the maximum ratings listed for extended periods of time. Exposure to such conditions may adversely impact product
reliability and result in failures not covered by warranty.
NOTES:
4. θ_JA is measured with the component mounted on a high effective thermal conductivity test board in free air. See Tech Brief TB379 for details.
5. For θ_JC, the “case temp” location is taken at the package top center.
Electrical Specifications Test Conditions: V_CC = 4.5V to 5.5V; Unless Otherwise Specified. Typicals are at V_CC = 5V, T_A = +25°C (Note 6).
Boldface limits apply over the operating temperature range, -40°C to +85°C.
