74LV123 Dual retriggerable monostable multivibrator with reset Rev. 05 — 8 November 2007 Product data sheet 1. General description The 74LV123 is a low-voltage Si-gate CMOS device and is pin and function compatible with the 74HC123; 74HCT123. It is a dual retriggerable monostable multivibrator which uses three methods to control the output pulse width: 1. The basic pulse time is programmed by the selection of an external resistor (REXT) and capacitor (CEXT). These are normally connected as shown in Figure 9. 2. Once triggered, the basic output pulse width may be extended by retriggering the gated active LOW-going edge input (nA) or the active HIGH-going edge input (nB). By repeating this process, the output pulse period (nQ = HIGH, nQ = LOW) can be made as long as desired (see Figure 12). 3. Alternatively, an output delay can be terminated at any time by a LOW-going edge on input nRD, which also inhibits the triggering (see Figure 13). Schmitt-trigger action in the nA and nB inputs makes the circuit highly tolerant of slower input rise and fall times. 2. Features s s s s s s s s Optimized for low-voltage applications: 1.0 V to 5.5 V Accepts TTL input levels between VCC = 2.7 V and VCC = 3.6 V Typical output ground bounce: < 0.8 V at VCC = 3.3 V and Tamb = 25 °C Typical HIGH-level output voltage (VOH) undershoot: > 2 V at VCC = 3.3 V and Tamb = 25 °C DC triggered from active HIGH or active LOW inputs Retriggerable for very long pulses up to 100 % duty factor Direct reset terminates output pulses Schmitt-trigger action on all inputs except for the reset input NXP Semiconductors 74LV123 Dual retriggerable monostable multivibrator with reset 3.

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 12.2 Power considerations 12.2.1 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 Figure 14. 12.2.2 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 Figure 14.
