Note 1) This item means VDD Voltage when Output Voltage is equal or less than 0.1V.
(Pull-up Resistor=470kW, Pull up Voltage=5V)
Note 2) VDET pin is pulled up to VDD via 470kW. tPLH means time interval from rising edge of VDD from
(-VDET)−2.0V to (-VDET)+2.0V to the point of Output Voltage being 80% of pull-up voltage.
