Logic Gates and Inverters are core components of digital logic circuits. Converting signals of various types into logic levels, logic gates and inverters provide the «building blocks» for all digital logic devices. 74AHCT86D is one of the main logic devices used today. This article will discuss the 118 application field of 74AHCT86D, as well as its working principle.

Application Field of 74AHCT86D

The 74AHCT86D is a type of Quad 2-Input XOR gate. It consists of four independent two-input XOR gates with the ability to select either active-low or active-high logic. This makes it a versatile logic device, capable of performing logic in a variety of applications, including:

• Power Management: The 74AHCT86D can be used to control power to different devices, by comparing a reference signal with an input signal. The output is then used as a signal to turn on or off the device.
• Address Decoding: The 74AHCT86D can be used to selectively decode two or more address lines in order to enable or disable certain components.
• Data Paths: This logic device can be used to construct hardwired data paths between two or more devices.
• Sequencing: The 74AHCT86D can be used to control and sequence the flow of data between different parts of an integrated system.

Working Principle of 74AHCT86D

The 74AHCT86D operates on the same principle as standard XOR gates, but with the added ability to select either active-low or active-high logic. This is achieved by using an active-low/active-high output enable pin, which can be used to select the type of logic output to be produced. When this pin is set to low, the XOR gate will produce an active-low logic output; when it is set to high, the XOR gate will produce an active-high logic output.

The 74AHCT86D also uses two input signals, which are compared against each other within the logic circuit. When the two input signals are the same, the output will be low; when the two input signals are different, the output will be high. This type of logic is often used to compare two signals in order to determine which one is greater, or to compare two signals to determine if they are equal.

Furthermore, the 74AHCT86D can also be used to construct various logic circuits using the four independent XOR gates that make up the device. By carefully connecting the input and output pins of the XOR gates, more complex digital logic circuits can be constructed, allowing for a wide range of applications.

Conclusion

The 74AHCT86D is a versatile logic device capable of performing several different types of digital logic. With the ability to select either active-low or active-high logic and the ability to construct complex logic circuits, the 74AHCT86D is a valuable tool for those working in the field of digital logic.
