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:
6. _JA is measured with the component mounted on a high effective thermal conductivity test board in free air. See Tech Brief TB379 for details.
7. For _JC, the “case temp” location is the center top of the package.
Analog Specifications V_CC = 2.7V to 5.5V, V_LOGIC = 1.2V to 5.5V over recommended operating conditions unless otherwise
stated. Boldface limits apply over the operating temperature range, -40°C to +125°C.
