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 re triggerable monostable multivibrator which uses three methods to control the output pulse width: 1. the basic pulse time is programmed by t he selection of an external resistor (r ext ) and capacitor (c ext ). 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 ou tput pulse period (nq = high, nq = low) can be made as long as desired (see figure 12 ). 3. alternatively, an output delay can be term inated at any time by a low-going edge on input nr d, 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 and benefits ? optimized for low-voltage applications: 1.0 v to 5.5 v ? accepts ttl input levels between v cc = 2.7 v and v cc = 3.6 v ? typical output ground bounce: < 0.8 v at v cc = 3.3 v and t amb = 25 ? c ? typical high-level output voltage (v oh ) undershoot: > 2 v at v cc = 3.3 v and t amb = 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 74LV123 dual retriggerable monostab le multivibrator with reset rev. 7 ? 12 december 2011 product data sheet
