MC14538BDR2

双精度Retiggerable /复式单稳多谐振荡器 Dual Precision Retiggerable/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 components, CXand RX. Output Pulse Width T = RX ° CXsecs

RX=Ω

CX = Farads
