The second will require only one IC, but only two gates can be made. Logic level gates like CD and flip-flops play a vital role in digital electronics.

OR gates with more inputs can be made up from the or any of the above ICs by cascading them together. If you are looking for an IC to perform logic level OR operation with two inputs, then this IC might be the right choice for you.

To visualize the output we have connected a LED to the output pin Q.

The arrangement of the CMOS components is shown below:. The truth table for the OR gate is shown below. If a is not available, there are several ways to achieve an OR gate.

As per the truth table shown above, when either one or both the input of the Gate is high the output will be high. If you have more than two inputs for your OR gate then you datasheef look into three input and four input OR gates. In other languages Add links.

The logic OR operation is very simple, since this is a two input OR gate we will have only two inputs which is A and B respectively. The resistor R is used to limit the current through the LED.
