74LV123 Dual retriggerable monostable multivibrator with reset Rev. 9 — 13 September 2021 Product data sheet 1. General description The 74LV123 is a dual retriggerable monostable multivibrator with reset. The basic output pulse width is programmed by selection of external components (REXT and CEXT). Once triggered this basic pulse width may be extended by retriggering either of the edge triggered inputs (nA or (nB). By repeating this process, the output pulse period (nQ = HIGH, nQ = LOW) can be made as long as desired. Alternatively, an output delay can be terminated at any time by a LOW-going edge on input nRD. Control inputs include clamp diodes. This enables the use of current limiting resistors to interface inputs to voltages in excess VCC. Schmitt-trigger action at nA and nB inputs makes the circuit tolerant of slower input rise and fall times. 2.

Retrigger timing The time to retrigger the monostable multivibrator depends on the values of REXT and CEXT. The output pulse width will only be extended when the time between the active going edges of the trigger pulses meets the minimum retrigger time.

Output pulse control using reset input nRD 11.2. Power considerations 11.2.1. Power-up When the monostable multivibrator is powered-up, it may produce an output pulse with a pulse width defined by the values of REXT and CEXT. This output pulse can be eliminated using the RC circuit on pin nRD shown in Fig. 14. 11.2.2. Power-down A large capacitor (CEXT) may cause problems when powering-down the monostable due to the energy stored in this capacitor. When a system containing this device is powered-down or a rapid decrease of VCC to zero occurs, the monostable may sustain damage, due to the capacitor discharging through the input protection diodes. To avoid this possibility, connect a damping diode DEXT (preferably a germanium or Schottky type diode) able to withstand large current surges. See Fig. 14.
