What is a Logic - Multivibrator?

A Logic - Multivibrator, also known as a flip-flop, is a 1-bit digital circuit with two stable states which can represent two different logical values. It is a type of multi-vibrator, a circuit that causes oscillations by switching between two different states at predetermined intervals. It is widely used in digital electronics, both in safety-critical and non-critical applications.

M74HC123RM13TR Application Field and Working Principle

The M74HC123RM13TR is a low-power, high-speed Bipolar CMOS (BiCMOS) logic family designed specifically for low voltage, and high speed applications. It is a multivibrator, meaning it can oscillate between two states, with a wide range of operating frequencies. It is used in short period applications, such as generating clock signals, as well as longer periods applications, such as in frequency division and pulse width modulation.

The M74HC123RM13TR consists of two inverters connected in a configuration known as a T-type flip-flop. It contains a set of two inputs, a set of two outputs, and two complementary outputs. The two inputs, labelled SET and RESET, control the state of the circuit. The outputs behave as an oscillator, generating a clock signal, changing state when the set input is asserted (high), and reverting to its original state when the reset input is asserted (low). The two complementary outputs Q and its complement /Q, both will be low when the circuit is in reset state. The two outputs will both be high when the circuit is in set state.

The M74HC123RM13TR can be used in a wide range of applications, such as frequency division, pulse width modulation, timing and control applications, and clock or data separation. In frequency division, the oscillator can be used to divide down the input frequency. In pulse width modulation, the circuit can be used to control the duty cycle of the output waveform. In control applications, the oscillator can be used to control the system timing, by providing a regular clock signal. The two outputs of the oscillator can also be used to separate clock from data signals.

The M74HC123RM13TR is designed with a wide range of operating characteristics. It has a limited power requirement of just 100µA, and a maximum propagation delay of 10 ns. It also boasts tight limits on monostability and astability. These features make it well suited for use in high speed, low power digital applications.

In conclusion, the M74HC123RM13TR is a versatile CMOS logic multivibrator designed for low power and high speed digital applications. Its T-type flip-flop configuration gives it two stable states which it can use to oscillate between two different logical values. It can be used in a wide range of applications, from frequency division and pulse width modulation, to data separation and control. Its design ensures it will handle the majority of low power, high speed digital applications.
