• Introduction

As a type of logic gate of digital electronic technique, SN74128NSR is designed to perform basic logic operations in a wide range of applications. It is an integrated circuit (IC) consisting of eight exclusive OR gate (ExOR gate) circuits. An ExOR gate is a logic circuit which produces an output that is the exclusive OR (ExOR) of the two inputs (for example, true if either, but not both, of the inputs is true). SN74128NSR application field and working principle are going to be explained in this article.

• Application Field

The SN74128NSR is a popular and widely used IC among all types of digital circuits. It has been found useful in many applications, including but not limited to:

• Logic gates and inverters: SN74128NSR can be used in logic gates and inverters to perform basic logic operations. Common uses include adding and subtracting binary digits, multiplying and dividing binary digits, and providing control signals to other circuits.
• Digital integrated circuits: SN74128NSR can be used as a device to interface with other digital integrated circuits, such as microprocessors and microcontrollers, to provide the logic interface necessary for complex digital operations.
• Measurement and automation: SN74128NSR can be used to measure and control industrial systems, such as factory machines and robotics.
• Medical devices: SN74128NSR can be used as a device to monitor and control medical devices, such as heart monitors, defibrillators, and respirators.

• Working Principle

The SN74128NSR is made up of 8 ExOR gates. An ExOR gate takes two inputs (A and B) and produces an output that is true only if A is true and B is false, or vice versa. The gate is symbolized as an inverted triangle, with the two inputs at the base and the output at the tip.Each ExOR gate has two inputs and one output. When input A is true and input B is false, the output is true. When input A is false and input B is true, the output is also true. When both inputs are true, or both inputs are false, the output is false. The ExOR gate can be used for basic logic operations, such as the addition and subtraction of binary digits, or for providing control signals to other circuits.For applications such as measurement and automation, the SN74128NSR can also be used to provide the necessary logic interface for digital integrated circuits. The SN74128NSR is an 8-bit ExOR integrated circuit, meaning it contains 8 separate ExOR gates which can be used to interface with other digital integrated circuits.

• Conclusion

The SN74128NSR is a popular and widely used logic gate IC, and is used in a wide range of applications. It is an 8-bit ExOR integrated circuit which consists of 8 separate ExOR gates. The SN74128NSR can be used in logic gates and inverters to provide basic logic operations, as well as to interface with other digital integrated circuits. It can also be used in applications such as measurement and automation, and medical devices.
