74LVC1G123-Q100 Single retriggerable monostable multivibrator; Schmitt trigger inputs Rev. 4 — 20 April 2021 Product data sheet 1. General description The 74LVC1G123-Q100 is a single retriggerable monostable multivibrator with Schmitt trigger inputs. Output pulse width is controlled by three methods: 1. The basic pulse is programmed by selection of an external resistor (REXT) and capacitor (CEXT). 2. Once triggered, the basic output pulse width may be extended by retriggering the gated active LOW-going edge input (A) or the active HIGH-going edge input (B). By repeating this process, the output pulse period (Q = HIGH) can be made as long as desired. Alternatively an output delay can be terminated at any time by a LOW-going edge on input CLR, which also inhibits the triggering. 3.
