During power-down, after delay time tpHL from moment VCC<VS-VHYS, VOUT will logic state. general, rated output current VCC, VOUT pulled down voltage within 0.4V from GND. (See Electrical Characteristics section). VOUT will logic state while VSVHYS>VCC>VOPR power-down operating. After falls below VOPR, output undefined.

Figure typical timing waveform AZ70XX during power-up temporary power-down period. Here some explanations AZ70XX's operation. During power-up period, VOUT will remain undefined until rises above VOPR (typically 0.8V). After that moment, output will become valid will logic state while VOPR<VCC<VS power-up operating. After delay time tpLH from moment VCC>VS, VOUT will logic high state. general, VOUT dependent upon voltage that pull resistor connected
