The first is to use a NOR gate and invert the output. The datasheey for the gate is controlled by using a switch connected to pin A and B of the Gate. The truth table for the OR gate is shown below. OR gates with more inputs can be made up from the or any of the above ICs by cascading them together.

The second will require only one IC, but only two gates can be made. This is discussed on this page. In other projects Wikimedia Commons. The resistor R is used to limit the current through the LED.
A selection of different manufacturers’ datasheets is given below:. 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. As per the truth table shown above, when either one or both the input of the Gate is high the output will be high.
The output of the OR gate is called as Q. If you have more than two inputs for your OR gate then you should look into three input and four input OR gates.
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. Submitted by admin on 2 July To visualize the output we have connected a LED to the output pin Q. The first method will require two ICs to implement, but a total of four gates can be made. This chip is different in pinout to the TTLbut can fulfill the function of its counterpart if the wiring is modified.
The truth table for one of the four gates is shown to the right. These are available from manufacturers.
