*Note1: Minimum operating voltage means the value of input voltage when output voltage maintains 0.1V or
less. (In the case of Nch Open Drain Output type, the output pin is pulled up with a resistance of
470kΩ to 5.0V.)
*Note2: In the case of CMOS Output type: The time interval between the rising edge of VDD input pulse from
0.7V to (+VDET)+2.0V and output voltage level becoming to VDD/2.
In the case of Nch Open Drain Output type: the output pin is pulled up with a resistance of 470kΩ to
5.0V, The time interval between the rising edge of VDD input pulse from 0.7V to (+VDET)+2.0V and out-
put voltage level becoming to 2.5V.

Note 1: In the case of CMOS output type; when the voltage is forced to VDD from 0.7V to (+VDET)+2.0V, time interval between the rising
edge of VDD and the reaching point at 50% of Output Voltage. In the case of Nch open drain output type : The output pin is
pulled up to 5V through 470kΩ,and when the voltage is forced to VDD from 0.7V to (+VDET)+2.0V, time interval between the ris-
ing edge of VDD and the reaching point ar 50% of Output Voltage.
Note 2: VDD value when Output Voltage is equal or less than 0.1V. In the case of Nch open drain output type, the output pin is pulled
up to 5V through 470kΩ resistor.
