ELECTRICAL CHARACTERISTICS
V_DD = 2.7 V to 5.5 V, V_H = V_DD, V_L = 0, T_A = -40ºC to +85ºC. Typical values are at V_DD = 2.7 V, T_A = 25ºC, unless
otherwise noted.

Notes:
(1) 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.
(2) Derate 3.1mW/ºC above T_A = +70ºC
