The 74LS32 is a Quad 2-input OR Gate integrated circuit. It is a logic gate that uses two or more inputs and produces one output.
The purpose of the 74LS32 is to combine two or more inputs into one single output.
The output is only high when one or more of the inputs are high. This makes it a useful device for combining multiple signals into one signal.
Are you building a project that will require the use of this IC? Here is a perfect guide for you.
We are going to discuss all that you should know about 74LS32 dual input OR Gate.
You will also learn the essence of choosing the best 74Ls32 supplier in China.
How does 74LS32 Dual Input OR Gate work?
This logic gate is a combination of two independent OR gates in one package. Each gate has two inputs, labeled A and B, and one output.
When either of the inputs A or B is HIGH (1) the output will be HIGH (1). If both inputs A and B are LOW (0) then the output will be LOW (0).
This gate can be used to combine two digital signals into one. When this gate is integrated in a circuit, it can be used to accept two input signals and produce a single output signal.
This can be used in a variety of applications, such as combining two digital audio signals into one, or as an input selector in a digital logic circuit
