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 in free air with the component mounted on a high effective thermal conductivity test board with “direct attach” features. See Tech
Brief TB379 for details.
5. For θ_JC, the “case temp” location is the center of the exposed metal pad on the package underside.
Electrical Specifications Test Conditions: V_CC = 3V to 3.6V, V_L = 1.8V ±10%, C₁ to C₄ = 0.1µF, Unless Otherwise Specified.
Typicals are at T_A = +25°C, V_CC = 3.3V, V_L = 1.8V, Unless Otherwise Specified. Boldface limits apply over the operating temperature range, -40°C
to +85°C.
