*Stresses above 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 above those indicated in the

operation sections of the specifications is not implied.

Exposure to Absolute Maximum Rating conditions for

extended periods may affect device reliability.

Note

VOS is measured as (VUT +VLT –2VREF)/2 where VUT is the upper hysteresis threshold and VLT is the lower hysteresis threshold with

VREF –VHYST set to 10mV. This represents the assymetry of the hysteresis thresholds around VREF.
