ELECTRICAL CHARACTERISTICS
V_CC = Full range, T_A = -40ºC to +85ºC unless otherwise noted. Typical values at T_A = +25ºC and V_CC = 3.3 V for
the C, S, T versions, V_CC = 5 V for the M version.

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) Production testing done at T_A = +25ºC; limits over temperature guaranteed by design only.
