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. Jedec Class II pulse conditions and failure criterion used. Level B exceptions are: Using a max positive pulse of 8.35V on all pins except X1 and
X2, Using a max positive pulse of 2.75V on X1 and X2, and using a max negative pulse of -1V for all pins.
5. 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.
6. For θ_JC, the “case temp” location is taken at the package top center.
DC Electrical Specifications Unless otherwise noted, V_DD = +2.7V to +5.5V, T_A = -40°C to +85°C, Typical values are at T_A = +25°C
and V_DD = 3.3V. Boldface limits apply over the operating temperature range, -40°C to +85°C.
