# Logic Function Selector?

• gastro54
In summary, the conversation discusses the building of a digital circuit to perform three logic functions using basic chips such as mux, demux, 555 timer, and logical chips. The suggestion is made to use a data selector such as the 74153. The conversation also touches on the difference between a digital circuit and an integrated circuit, with the latter being able to be either digital, analog, or mixed signal in nature.

Hi,

I'm trying to build a digital circuit that will perform one of three logic functions on a set of three inputs A B C based on the input value of a counter that counts mod-3 (00, 01, 10).

I can use basic chips such as mux, demux, 555 timer, logical chips

Thanks

Look for the 74153. It is a data selector (TTL).

Welcome to the PF, gastro. We do not do your homework/coursework for you here at the PF. You must post your own work on the problem, before we can offer any hints or tutorial thoughts.

what is the difference between digital circuit and integrated circuit(IC)?

## What is a Logic Function Selector?

A Logic Function Selector is a device or tool that allows you to select and control different logic functions within a system or circuit. It is used to switch between different logical operations, such as AND, OR, and NOT, to achieve desired results.

## How does a Logic Function Selector work?

A Logic Function Selector works by receiving input signals and using switching mechanisms to manipulate those signals based on the selected logic function. It uses logic gates, such as transistors, to control the flow of electricity and produce the desired output.

## What are some common uses of a Logic Function Selector?

A Logic Function Selector is commonly used in electronic devices and systems, such as computers, calculators, and digital circuits. It is also used in industrial applications, such as control systems and robotics, to perform complex logical operations.

## What are the advantages of using a Logic Function Selector?

Using a Logic Function Selector allows for flexibility and versatility in designing and controlling logical operations. It also reduces the number of components needed in a system, making it more efficient and cost-effective.

## Are there different types of Logic Function Selectors?

Yes, there are different types of Logic Function Selectors, including multiplexers, demultiplexers, and programmable logic devices. Each type has its own unique features and functions, but they all serve the purpose of selecting and controlling logic functions.
