Logic multivibrators are electronic circuits that are commonly used in oscillators to generate pulses in electronics. The MM74HC123AN is a Dual retriggerable monostable multivibrator integrated circuit that can be used to create a pulse width of varying duration. This chip is also specified to work with a supply voltage of 2.0 volts to 6.0 volts.

The MM74HC123AN consists of two identical circuits internally wired together. Each circuit includes a flip-flop, two 2-input NAND gates, two 2-input NOR gates, and two inverters. Inputs of the 1st NOR gate in each circuit are connected to the active HIGH (supply voltage) and active LOW (ground). Outputs of the 2-input NOR gate in each circuit are connected to the outputs of the flip-flop, providing the retriggerable monostable multivibrator functionality.

The MM74HC123AN multivibrator has two trigger inputs, two trigger outputs, and two reset inputs. When one of the trigger inputs (T1 or T2) receives a rising edge and is then maintained, the opposing trigger output (T1 or T2) is activated and remains high until the reset input is activated. Reset terminals disable the timing sequence upon receiving a high-level pulse.

The MM74HC123AN monostable multivibrator also has Schmitt Trigger action at the trigger inputs which helps to reduce any bounce or jitter on the clock signals.

The MM74HC123AN has a wide range of applications, especially in digital delay generators, timing applications, and pulse width modulators. It can be used to delay, disrupt, or filter digital input signals. The voltage levels of the input and output signals of the MM74HC123AN are dependent on the supply voltage of the circuit.

The MM74HC123AN is commonly used for timing sequences and for clock cleaning. The MM74HC123AN is capable of producing a wide range of different times and this makes it very versatile for timing applications. The reset terminal allows for further control of the timing sequence which allows for more precise and accurate timing.

The MM74HC123AN is also used in pulse width modulators. This type of circuit is used to control the on and off times of a signal, allowing different output signals to be created. This chip can be used in motor and servo control, as well as in audio amplifiers and loudspeakers.

Overall, the MM74HC123AN is a versatile and cost-effective solution for a wide range of different timing and pulse-width modulation applications. The retriggerable monostable multivibrator is easy to use and can provide reliable and accurate results.
