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.

ELECTRICAL CHARACTERISTICS
(VCC = +3.0V to +5.5V, VDD = +3.0V to +3.6V, TA = -40NC to +85NC, unless otherwise noted. Typical values are at VCC = VDD = +3.3V,
TA = +25NC.) (Note 2)
ABSOLUTE MAXIMUM RATINGS
Note 1: Signals on SEL_, NO_, NC_, or COM_ exceeding VCC, VDD, or VGND are clamped by internal diodes. Limit forward-diode
current to maximum current rating.
