*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 Type, Output pin is pulled up with a resistance of 470k
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: Output pin is pulled up with a resistance of 470k
to 5.0V, The
time interval between the rising edge of VDD input pulse from 0.7V to (+VDET)+2.0V and output voltage level
becoming to 2.5V.
