Dual Retriggerable Monostable Multivibrator With Reset

The 74LV423 is a low-voltage Si-gate CMOS device and is pin and function compatible with the 74HC/HCT423. The 74LV423 is a dual retriggerable Monostable Multivibrator with output pulse width control by three methods. The basic pulse time is programmed by selection of an external resistor (REXT) and capacitor (CEXT). They are normally connected as shown in Figure 1. 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. Alternatively, an output By NXP Semiconductors
