The input for the gate is controlled by using a switch connected to pin A and B of the Gate. 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. A pull down resistor of k is used to hold the logic to low logic 0 when the switch is left floating.

The output of the OR gate is called as Q. The truth table for the OR gate is shown below. Retrieved from ” https: To visualize the output we have connected a LED to the output pin Q.
This is discussed on this page. As per the truth table shown above, when either one or both the input of the Gate is high the output will be high.
Submitted by admin on 2 July For more information about the OR gate in general, see this module.
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. Logic level gates like CD and flip-flops play a vital role in digital electronics.

If you have more than two inputs for your OR gate then you should look into three input and four input OR gates. TL — Programmable Reference Voltage. The second will require only one IC, but only two gates can be made. These are available from manufacturers. The arrangement of the CMOS components is shown below:. The first method will require two ICs to implement, but a total datxsheet four gates can be made. Policies and guidelines Contact us.
This page was last edited on 16 Decemberat Meaning it has four OR gate IC inside it, each of which can be utilized independently.
OR gates with more inputs can be made up from the or any of the above ICs by cascading them together. This chip is different in pinout to the TTLbut can fulfill the function of its counterpart if the wiring is modified. If a is not available, there are several ways to achieve an OR gate.
