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:
1. θ_JA is measured with the component mounted on an evaluation PC board in free air.
Electrical Specifications V_DD = 5V, V_SS = 0V, T_A = +25°C, Unless Otherwise Specified
