ILKG Open-drain output leakage current (V+) = VO = 5V; VID = 1V 0.1 20 nA
ILKG Open-drain output leakage current (V+) = VO = 36V; VID = 1V 0.3 50 nA
IOL Low Level Output Current VOL = 1.5V; VID = -1V; VS = 5V 6 21 mA
The voltage at either input can not be allowed to go negative by more than 0.3V otherwise output can be incorrect and excessive input current can flow. The upper end of the common-mode voltage range is limited by VCC – 2V. However only one input needs to be in the valid common mode range, the other input can go up the maximum VCC level and the comparator provides a proper output state. Either or both inputs can go to maximum VCC level without damage.
