OR gates with more inputs can be made up from the or any of the above ICs by cascading them together. 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. If you have more than two inputs for your OR gate then you should look into three input and four input OR gates.

From Wikibooks, open books for an open world. This is discussed on this page. The output of the OR gate is called as Q. The first method will require two ICs to implement, but a total of four gates can be made. Logic level gates like CD datasbeet flip-flops play a vital role in digital electronics.

If a is not available, there are several ways to achieve an OR gate. The input for the datasheeh 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 cd471.

Views Read Edit View history. For more information about the OR gate in general, see this module.

As per the truth table shown above, when either one or both the input of the Gate is high the output will be high. To visualize the output we have connected a LED to the output pin Q. This chip is different in pinout to the TTLbut can fulfill the function of its counterpart if the wiring is modified.


The resistor R is used to limit datasheer current through datasheef LED. In other projects Wikimedia Commons.

The first is to use a NOR gate and invert the output. These are available from manufacturers. The truth table for one of the four gates is shown to the right. A pull down resistor of k is used to hold the logic to low logic 0 when the switch is left floating. The arrangement of the CMOS components is shown below:.
