Please use this IC within the stated maximum ratings. The IC is liable to malfunction should the ratings be exceeded.
When a resistor is connected between the V

It is therefore recommend that no resistor be added. ( refer to N.B. 1 - (1) below )
When a resistor is connected between the V
output configurations, oscillation may occur as a result of through current at the time of voltage release even if load

the occurences of oscillation as described above.
Further, please ensure that R
release voltages will rise due to voltage drops at R
Depending on circuit's operation, transient delay time of this IC can be widely changed due to upper limits or lower limits
of operational ambient temparature.
When the voltage applied at IN rises, release operations commence and the detector's output voltage increases. Load

the input (IN) and the V
voltage level at the V
commence. Following detect operations, load current flow will cease and since voltage drop at R

Oscillation may occur with this " release - detect - release " repetition.
Further, this condition will also appear via means of a similar mechanism during detect operations.
Since the XC61F series are CMOS IC
release and detect operations ). Consequently, oscillation is liable to occur during release voltage operations as a result
of output current which is influenced by this through current ( Diagram 3 ).
Since hysteresis exists during detect operations, oscillation is unlikely to occur.
