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 6V may exceed the rated terminal current. Operation

from higher voltage supplies requires a series dropping resistor. See

Applications Information.

Note 4: Threshold voltages have no hysteresis unless the part is in

comparator mode. Hysteresis is one-sided, affecting only invalid-to-valid

transitions. See Applications Information.
