Working Principles

The SN74AHCT123ADGVR is a dual retriggerable monostable multivibrator. It consists of two independent monostable circuits that can be triggered individually. The multivibrator generates an output pulse of a fixed duration when triggered, which can be extended by applying additional trigger pulses during the pulse width.

The circuit operates using CMOS technology, allowing for high-speed operation while consuming low power. The clear input resets the multivibrator to its initial state, terminating the output pulse. External resistors and capacitors are required to set the desired pulse width and timing characteristics.
