Note 1: Stresses beyond those listed under Absolute Maximum Ratings

may cause permanent damage to the device. Exposure to any Absolute

Maximum Rating condition for extended periods may affect device

reliability and lifetime.

Note 2: All currents into pins are positive; all voltages are referenced to

GND unless otherwise noted.

which exceeds 5.7V may exceed the rated terminal current. Operation

from higher voltage supplies requires a series dropping resistor. See

Applications Information.

Note 4: Input impedance is dependent on the configuration of the SEL

pins.
