■Functional Description
●Functional Description
2
q When input voltage (VIN) rises above detect voltage (VDF), output voltage (VOUT) will be equal to VIN.
( A condition of high impedance exists with Nch open drain output configurations. )
w When input voltage (VIN) falls below detect voltage (VDF), output voltage (VOUT) will be equal to the ground voltage (VSS)
level.
e When input voltage (VIN) falls to a level below that of the minimum operating voltage (VMIN), output will become unstable.
In this condition, VIN will equal the pulled-up output ( should output be pulled-up.)
r When input voltage (VIN) rises above the ground voltage (VSS) level, output will be unstable at levels below the minimum
operating voltage (VMIN). Between the VMIN and detect release voltage (VDR) levels, the ground voltage (VSS) level will be
maintained.
t When input voltage (VIN) rises above detect release voltage (VDR), output voltage (VOUT) will be equal to VIN.
( A condition of high impedance exists with Nch open drain output configurations. )
y The difference between VDR and VDF represents the hysteresis range.

■Directions for use
●Notes on Use
When a resistor is connected between the VIN pin and the input with N-channel open
drain output configurations, we suggest that a resistor with an RIN value of less than
1k Ω and a capacitor with a value of more than 0.1 µF be used in order to avoid
