4 to 1 multiplexer circuit diagram and truth table

A 4 to 1 Multiplexer circuit is an essential part of today’s digital electronics. It is a powerful device that can switch between multiple inputs and outputs with just one control signal. It allows electrical engineers to easily combine several inputs into one output. This article will explain the basics of a 4 to 1 Multiplexer circuit, including its diagram and truth table.

The 4 to 1 Multiplexer circuit consists of four active-high control signals, one enable signal, and four data input lines. When the enable signal is high, the 4 to 1 Multiplexer circuit is enabled, allowing the four data input lines to be selected from one output line. The four data input lines each have a different value – 0, 1, 2, or 3 – which corresponds to the binary values of 0, 1, 10, or 11. The enable signal is used to select the data line that will be connected to the output.

The truth table for a 4 to 1 Multiplexer circuit shows the different conditions of the output based on the combination of control signals and data input lines. For example, if the enable signal is 0, the output will always remain low regardless of the data input lines. On the other hand, if the enable signal is 1, the output will be equal to the value of the data input line that is selected by the four active-high control signals. It is important to note that the 4 to 1 Multiplexer circuit can only select one of the data lines at a time; it cannot select multiple data input lines at once.

Overall, the 4 to 1 Multiplexer circuit is a simple yet powerful device that is widely used in digital electronics. With its easy-to-understand diagram and concise truth table, it allows engineers to quickly and easily combine multiple inputs into one output. Next time you come across a complex digital circuit involving multiplexers, you’ll know exactly how it works.
