ABSOLUTE MAXIMUM RATINGS
ELECTRICAL CHARACTERISTICS
(Pin 13 (HFPD) and pin 14 (LFPD) are not connected. Typical values are at V
CC
= +3.3V, V
CC1
= V
CC2
= 1.8V, T
A
= +25
°C, unless
otherwise noted.) (Values at -40°C are guaranteed by design and characterization.)
Stresses beyond 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 beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
