The 74HCT123N,652 is a popular IC component that belongs to the 74HCT family of high-speed CMOS logic integrated circuits. It is a dual, retriggerable monostable multivibrator, also known as a "one-shot" or "pulse stretcher" IC. This particular variant, the 74HCT123N,652, is designed to work with a voltage supply range of 2V to 6V. Here is an overview of its key features:
1. Dual Monostable Multivibrator: This IC contains two independent retriggerable monostable multivibrators. Each multivibrator can be triggered individually using external or internal signals, producing an output pulse width that is determined by external timing components.
2. Retriggerable Operation: The 74HCT123N,652 allows retriggerable operation, meaning that if a trigger pulse is applied while an output is already ON, it will restart the output pulse width timing cycle. This feature provides flexibility in pulse stretching applications.
3. Wide Range of Pulse Widths: The pulse width of the output signals can be adjusted with external resistor-capacitor (RC) timing components. The range of achievable pulse widths varies from a few nanoseconds to hundreds of milliseconds, depending on the values of the external components
