■NOTES ON USE
2. The power supply input pin voltage drops by the resistance between power supply and the V
3. When the setting voltage is less than 1.0V, be sure to separate the V
4. Note that a rapid and high fluctuation of the power supply input pin voltage may cause a wrong operation.
5. Power supply noise may cause operational function errors, Care must be taken to put the capacitor between V
6. When there is a possibility of which the power supply input pin voltage falls rapidly (e.g.: 6.0V to 0V) at release operation
7. In N channel open drain output, V

and the Cd pin as the Figure 3 shown below.

operation of the IC. At this time, the operation may be wrong if the power supply input pin voltage falls below the minimum
operating voltage range. In CMOS output, for output current, drops in the power supply input pin voltage similarly occur.
Moreover, in CMOS output, when the V
occur if the drops in voltage, which caused by through current at operation of the IC, exceed the hysteresis voltage. Note it
especially when you use the IC with the V
