COMMENT
Stresses above those listed under “Absolute Maximum Ratings” may
cause permanent damage to the device. These are stress ratings only,
and functional operation of the device at these or any other conditions
outside of those listed in the operational sections of this specification is not
implied. Exposure to any absolute maximum rating for extended periods
may affect device performance and reliability.
ELECTRICAL CHARACTERISTICS
(V_DD = 2.7 V to 5.5 V, V_H = V_DD, V_L = 0, T_A = -40˚C to 85˚C. Typical values are at V_DD = 2.7 V, T_A = 25˚C, unless
otherwise noted).
