Logic level gates like CD and flip-flops play a vital role in digital electronics. 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. In other languages Add links. In other projects Wikimedia Commons. This is discussed on this page. The second will require only one IC, but only two gates can be made.

The truth table for the OR gate is shown below. The first method will require two ICs to implement, but a total of four gates can be made.


A selection of different manufacturers’ datasheets is given below:. Submitted by admin on 2 July A pull down resistor of k is used to hold the logic to low logic 0 when the switch is left floating.

Meaning it has four OR gate IC inside it, each of which can be utilized independently. For more information about the Datashdet gate in cd44071, see this module.

The truth table for one of the four gates is shown to the right. 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.

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 c4071 Gate is high the output will be high. If you have more than two inputs for your OR gate then you should cc4071 into three input and four input OR gates.

The first is to use a NOR gate and invert the output.


The output of the OR gate is called as Q. By using this site, you agree to the Terms of Use and Privacy Policy. The arrangement of the CMOS components is shown below:.

Retrieved from ” https: The input for the gate is controlled by using a switch connected to pin A and B of the Gate. This page was last edited on 16 Decemberat Policies and guidelines Contact us.

These are available from manufacturers. To visualize the output we have connected a LED to the output pin Q. datasheey

Complete Technical Details can be found at the CD datasheet provided below this article. The resistor R is used to limit the current through the LED.
