Power-down consideration
A large capacitor (C
powering-down the monostable due to the energy stored
in this capacitor. When a system containing this device is
powered-down or a rapid decrease of V
the monostable may substain damage, due to the
capacitor discharging through the input protection diodes.
To avoid this possibility, use a damping diode (D
preferably a germanium or Schottky type diode able to
withstand large current surges and connect as shown in
Fig.17.
