Note:
(1) Stresses above those listed under âAbsolute Maximum Ratingsâ 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 speciï¬cation
is not implied. Exposure to any absolute maximum rating for extended periods may affect device performance and reliability.
ELECTRICAL CHARACTERISTICS
VCC = Full range, TA = -40ºC to +85ºC unless otherwise noted. Typical values at TA = +25ºC and VCC = 3.3V for the
T/S versions, VCC = 5V for the M version.
