Retrieved from ” https: The truth table for one of the four gates is shown to the right. The logic Datxsheet operation is very simple, since this is a two input OR gate we will have only two inputs which is A and B respectively. A pull down resistor of k is used to hold the logic to low logic 0 datashdet the switch is left floating. The first is to use a NOR gate and invert the output. For more information about the OR gate in general, see this module.


The second will require only one IC, but only two gates can be made. Complete Technical Details can be found at datasheett CD datasheet provided below this article.

The truth table for the OR gate is shown below. This is discussed on this page.

A selection of different manufacturers’ datasheets is given below:. This chip is different in pinout to the TTLbut can fulfill the function of its counterpart if the wiring datashet modified.

The input for the gate is controlled by using a switch connected to pin A and B of the Gate. From Wikibooks, open books for an open world.

These are available from manufacturers. 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. The first method will require two ICs to implement, but a total of four gates can be made.

The arrangement of the CMOS components is shown below:. Logic level gates like CD and flip-flops play a vital role in digital electronics.

To visualize the output we have connected a LED to the output pin Q. OR gates with more inputs can be made up from the or any of the above ICs by cascading them together.

Meaning it has four OR gate IC inside it, each of which can be utilized independently. The resistor R is used to limit the current through the LED. If a is not available, there are several ways to achieve an OR dayasheet. This page was last edited on 16 Decemberat
