HD74LS122  
Retriggerable Monostable Multivibrator (with Clear)  
REJ03D0428–0200  
Rev.2.00  
Feb.18.2005  
This d-c triggered multivibrator features output pulse width control by three method. The basic pulse time is  
programmed by selection of external resistance and capacitance values. The HD74LS122 has internal timing resistor  
that allows the circuit to be used with only an external capacitor, if so desired. Once triggered, the basic pulse width  
may be extended by retriggering the gated low-level -active (A) or high-level active (B) inputs or be reduced by use of  
the overriding clear. Figure 1 illustrates pulse control by retriggering and early clear. This device is provided enough  
Schmitt hysteresis to ensure jitter-free triggering from the B input with transition rates as slow as 0.1 mV/ns.
