SN74123N

Logic-Multivibrators are oscillators that act as memory elements. If the input signal applied is the same or similar to the output waveform, then the circuit is called a multivibrator. SN74123N is a monolithic dual retriggerable monostable multivibrator, which is widely used in various applications. It consists of two linear equivalent circuits that can be either triggered or retriggered in a single monostable mode.

The SN74123N consists of two identical circuits, each composed of an inverter, an upper comparator, and a lower comparator. The four inputs consist of a reset (R) pin and two active high (A1 and A2) pins, which can be used to trigger and retrigger the circuit.

When the A1 pin is activated, it sets the circuit in a one-shot mode, causing the output to go high. The A2 pin can also be used to retrigger the circuit, allowing the circuit to remain in a one-shot mode for longer periods of time. When the R pin is activated, the circuit is reset and the output goes low.

The SN74123N is a dual retriggerable monostable multivibrator, which can be used to implement various types of time delays and pulse-width modulation circuits. It is particularly suitable for many automotive control applications, such as fuel injection systems, ignition control, and anti-lock braking systems. It can also be used as a clock generator in conjunction with other logic devices.

In addition, the SN74123N can be used in logic level conversion applications and it is also suitable for use in data transmission and communication systems. It is typically used in combination with other logic devices, such as shift registers, for data conversion and data transmission.

The SN74123N is also widely used in power supply and machine control systems, such as servo motors, motor speed controllers, and regulators. In these applications, the SN74123N can be used to provide accurate timing and synchronization of control signals.

Overall, the SN74123N is a versatile and reliable circuit for a wide range of applications. Its ease of use and simple schematic make it an ideal choice for a variety of logic-based applications. With the help of its dual retriggerable monostable mode and controllable pulse width, the SN74123N is able to provide accurate time delays, pulse width modulation, and conversion of logic signals.
