■OPERATIONAL EXPLANATION
(Especially explained for the CMOS output products)
① When input voltage (VIN) is higher than detect voltage (VDF), output voltage (VOUT) will be equal to VIN.
(A condition of high impedance exists with N-ch open drain output configurations.)
② When input voltage (VIN) falls below detect voltage (VDF), output voltage (VOUT) will be equal to the ground voltage
(VSS) level.
③ When input voltage (VIN) falls to a level below that of the minimum operating voltage (VMIN), output will become
unstable.(As for the N-ch open drain product of XC61CN, the pull-up voltage goes out at the output voltage.)
④ 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.
⑤ 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 N-ch open drain output configurations.)
⑥ The difference between VDR and VDF represents the hysteresis range.

■NOTES ON USE
1. Please use this IC within the stated absolute maximum ratings. For temporary, transitional voltage drop or voltage rising
phenomenon, the IC is liable to malfunction should the ratings be exceeded.
2. When a resistor is connected between the VIN pin and the power supply with CMOS output configurations, oscillation may
occur as a result of voltage drops at RIN if load current (IOUT) exists. (refer to the Oscillation Description (1) below)
3. When a resistor is connected between the VIN pin and the power supply with CMOS output configurations, irrespective of
N-ch open-drain output configurations, oscillation may occur as a result of through current at the time of voltage release
even if load current (IOUT) does not exist. (refer to the Oscillation Description (2) below )
4. Please use N-ch open drain output configuration, when a resistor RIN is connected between the VIN pin and power
source.
In such cases, please ensure that RIN is less than 10kΩ and that C is more than 0.1μF, please test with the actual device.
(refer to the Oscillation Description (1) below)
5. With a resistor RIN connected between the VIN pin and the power supply, the VIN pin voltage will be getting lower than the
power supply voltage as a result of the IC's supply current flowing through the VIN pin.
6. In order to stabilize the IC's operations, please ensure that VIN pin input frequency's rise and fall times are more than 2 μ
s/ V.
7. Torex places an importance on improving our products and its reliability.
However, by any possibility, we would request user fail-safe design and post-aging treatment on system or equipment.

●Oscillation Description
(1) Load current oscillation with the CMOS output configuration
When the voltage applied at power supply, release operations commence and the detector's output voltage increases.
Load current (IOUT) will flow at RL. Because a voltage drop (RIN x IOUT) is produced at the RIN resistor, located between the
power supply and the VIN pin, the load current will flow via the IC's VIN pin. The voltage drop will also lead to a fall in the
voltage level at the VIN pin. When the VIN pin voltage level falls below the detect voltage level, detect operations will
commence. Following detect operations, load current flow will cease and since voltage drop at RIN will disappear, the
voltage level at the VIN pin will rise and release operations will begin over again.
Oscillation may occur with this " release - detect - release " repetition.
Further, this condition will also appear via means of a similar mechanism during detect operations.
(2) Oscillation as a result of through current
Since the XE61C series are CMOS IC S, through current will flow when the IC's internal circuit switching operates (during
release and detect operations). Consequently, oscillation is liable to occur as a result of drops in voltage at the through
current's resistor (RIN) during release voltage operations. (refer to Figure 3)
Since hysteresis exists during detect operations, oscillation is unlikely to occur.
