■NOTES ON USE
1. Use this IC within the stated maximum ratings. Operation beyond these limits may cause degrading or permanent
2. The input pin voltage drops by the resistance between power supply and the V
3. Note that a rapid and high fluctuation of the input pin voltage may cause a wrong operation.
4. Power supply noise may cause an operational function error. Care must be taken to put an external capacitor between
5. When there is a possibility of which the input pin voltage falls rapidly (e.g.: 6.0V to 0V) at release operation with the delay
6.
Therefore, pull-up resistance should be selected 25kΩ or below.

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