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.

Note 1: All devices are production tested at 25°C. All temperature limits are guaranteed by design.

Note 2: Comparator Input Offset is defined as the center of the hysteresis zone.

Note 3: Hysteresis is defined as the difference of the trip points required to change comparator output states.

Note 4: VOD is the overdrive voltage beyond the offset and hysteresis-determined trip points.

Note 5: Rise and fall times are measured between 10% and 90% at OUT.
