Note 6:
Both hysteresis and offset are measured by determining positive may cause permanent damage to the device. Exposure to any Absolute and negative trip points (input values needed to change the output in the Maximum Rating condition for extended periods may affect device opposite direction). Hysteresis is defined as the difference of the two trip reliability and lifetime. points and offset as the average of the two trip points.

Note 5:
Total output supply voltage range is guaranteed by the PSRR_VDD from 10% of V test. Total input supply voltage range for the LTC6752-2, LTC6752-3 and DD - VEE to 90% of VDD - VEE for the LTC6752-2/ LTC6752-3/LTC6752-4, and from 10% of V LTC6752-4 is guaranteed by the PSRR_V CC - VEE to 90% of VCC - VEE CC test.
