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.
NOTE:
4. θ_JA is measured with the component mounted on a low effective thermal conductivity test board in free air. See Tech Brief
TB379 for details.
Electrical Specifications
Test Conditions: V_CC = 3.3V ±10%, C₁ - C₄ = 0.1µF; Unless Otherwise Specified.
Typicals are at T_A = +25°C. Boldface limits apply over the operating temperature
range, -55°C to +125°C.
