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 (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 (n a) or the active high-going edge input (nb). by repeating this process, the output pulse period (nq = high, n q = 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 n rd, which also inhibits the triggering (see figure 13 ). schmitt-trigger action in the n a and nb inputs makes the circuit highly tolerant of slower input rise and fall times. 2. features n optimized for low-voltage applications: 1.0 v to 5.5 v n accepts ttl input levels between v cc = 2.7 v and v cc = 3.6 v n typical output ground bounce: < 0.8 v at v cc = 3.3 v and t amb = 25 c n typical high-level output voltage (v oh ) undershoot: > 2 v at v cc = 3.3 v and t amb =25 c n dc triggered from active high or active low inputs n retriggerable for very long pulses up to 100 % duty factor n direct reset terminates output pulses n schmitt-trigger action on all inputs except for the reset input 74lv123 dual retriggerable monostable multivibrator with reset rev. 05 8 november 2007 product data sheet
