The thres hold defines the minimum allowed voltage which guarantees the good functionality of the system. As long as VDD stays upside this voltage level, the output stays inactive. If VDD drops below VTH, the output gets active. When V DD rises above VTH, the output remains active for an additional 290 ms (typ.). This al lows the system to stabilize before getting fully active. The threshold v oltage may be obtained in differ ent versions: 2.0 V, 2.4 V, 2.8 V, 3.5 V, 4.0 V, 4.5 V.
