... 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 ...
