... MC14538B Dual Precision Retriggerable/Resettable Monostable Multivibrator The MC14538B is a dual, retriggerable, resettable monostable multivibrator. It may be triggered from either edge of an input pulse, and produces an accurate output pulse over a wide range of widths, the duration and accuracy of which are determined by the external timing ...

... POWER–DOWN CONSIDERATIONS Large capacitance values can cause problems due to the large amount of energy stored. When a system containing the MC14538B is powered down, the capacitor voltage may discharge from V through the standard protection diodes DD at pin 2 or 14. Current through the protection diodes should ...
