These dc triggered multivibrators feature pulse width control by  
three methods. The basic pulse width is programmed by selection of  
external resistance and capacitance values. The LS122 has an internal  
timing resistor that allows the circuits to be used with only an external  
capacitor. 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.
