Introduction:

The MC74AC86D is a 4-input XOR/XNOR gate device. It is one of the most commonly used logic gates and inverters in electronic systems. The MC74AC86D is a dual 4-input, single output gate and it is capable of logic operations including addition, subtraction, exclusive or, AND, OR and NOT. The MC74AC86D is a monolithic integrated circuit made of complementary silicon-gate CMOS (complementary metal–oxide–semiconductor) technology.

Application:

The MC74AC86D is used in various types of applications from digital signal processing, signal conditioning, and analog switching. The chip is ideal for logic operations which require the implementation of several logic operations, such as addition, subtraction, and multiplication. The MC74AC86D allows for the easy implementation of up to four logic operations, without any additional components, in a single package. This provides significant savings in design, power consumption, and board real estate. The MC74AC86D is also ideal for data processing, decimal counter, alarm systems, arithmetic operations, and bus multiplexing. It can also be used in logic gates and in single-chip microprocessors.

Working Principle:

The MC74AC86D consists of four independent XOR/XNOR gates. The output of the gates is defined by the following equations: Output=A XOR B XOR C XOR D and Output=A XNOR B XNOR C XNOR D. A and B are the two inputs to one XOR / XNOR gate, C and D are used to control the output of other logic gate. For example, if C and D are both low, the output is A XOR B; if C and D are both high, the output is A XNOR B. Similarly for the other two XOR/XNOR gates, if C and D are both low, the output is A XOR B XOR C XOR D and if C and D are both high, the output is A XNOR B XNOR C XNOR D.

In addition to its logic functionality, the MC74AC86D also has many features that make it an ideal choice for a variety of applications. It has a very low power consumption and low noise, making it suitable for low-power applications. The circuit also has a wide temperature range and is tolerant to voltage variations. Furthermore, the chip has a high-speed output switch and includes a Schmitt trigger input circuit which allows the chip to detect small pulse levels. This makes it useful for applications that require high switching speed, as well as applications that require reliable signal detection.
