ABSOLUTE MAXIMUM RATINGS
ELECTRICAL CHARACTERISTICS
(V CC = +3.3V ±10%, T A =T MIN to T MAX, unless otherwise noted. Typical values are at V CC = +3.3V, T A = +25°C, unless otherwise
noted.) (Note 3)
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.
(All voltages referenced to GND, unless otherwise noted.)

Note 1: Signals on SEL, _IN_, _OUTA_, _OUTB_ exceeding V CC or GND are clamped by internal diodes. Limit forward-diode current
to maximum current rating.
Note 2: Package thermal resistances were obtained using the method described in JEDEC specification JESD51-7, using a 4-layer
board. For detailed information on package thermal considerations, refer to www.maxim-ic.com/thermal-tutorial .
