Fig.11 Power-down protection circuit.
Power-down considerations
A large capacitor (CX) may cause problems when
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 VCC to zero occurs,
the monostable may sustain damage, due to the capacitor
discharging through the input protection diodes. To avoid
this possibility, use a damping diode (DX) preferably a
germanium or Schottky type diode able to withstand large
current surges and connect as shown in Fig.11.
