As long as VDD stays inside this voltage window, the output stays inactive. If V DD drops below VTHlow, or rises above VTHhigh, the output gets active. This allows the system to stabilize before getting fully active. The lower thresho ld voltage may be obtained in different versions: 2.0 V to 6 V 2.4 V to 6 V 2.8 V to 6 V 3.5 V to 6 V 4.0 V to 6 V 4.5 V to 6 V...
