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 components, CXand RX. Output Pulse Width T = RX ° CX(secs)
●RX=Ω
●CX = Farads
