2. Delay Circuit
The delay circuit delays the output signal from the time at which the power voltage (V

2. Print circuit board layout should be made in such a way that no current flows into or
flows from the CD pin since the impedance of the CD pin is high, otherwise correct
delay time cannot be provided.
current of the capacitor can be ignored against the built-in constant current value.
Leakage current causes deviation in delay time. When the leakage current is larger
than the built-in constant current, no release takes place.
avoid the double pulse, attach 20 pF or larger capacitor to the CD pin. Do not apply
voltage to the CD pin.
