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 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: the 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.
