Working Principles

The SN74LV123ARGYR is a dual retriggerable monostable multivibrator. It generates a pulse of a specific duration when triggered by an external signal. The duration of the pulse is determined by the external resistor-capacitor timing components connected to the RCext pin. The device can be retriggered during the pulse width period, extending the output pulse duration.
