Working Principles

The SN74LV123ADGVR is a dual retriggerable monostable multivibrator. It generates precise time delays or pulses based on the input trigger signal. When a trigger pulse is applied, the output Q changes state for a specific duration determined by the external resistor and capacitor connected to the RC pin. The CLR pin can be used to clear the output and initiate a new timing cycle.
