This is discussed on this page. The first method will require two ICs to implement, but a total of four gates can be made.

Practical Electronics/IC/4071

If a is not available, there are several ways to achieve an OR gate. To visualize the output we have connected a LED datwsheet the output pin Q. Retrieved from ” https: In other languages Add links.

In other projects Datashet Commons. Complete Technical Details can be found at the CD datasheet provided below this article. The output of the OR gate is called as Q. The arrangement of the CMOS components is shown below:.


For more information about the OR gate in general, see this module. If you have more than two inputs for your OR gate then you should look into three input and datasbeet input OR gates. This page was last edited on 16 Decemberat These are available from manufacturers.

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. By using this site, you agree to the Terms of Use and Privacy Policy.

As per the truth table shown above, when either one or both the input of the Gate is high the output will be high. Policies and guidelines Contact us.

From Wikibooks, open books for an open world. 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. A pull down resistor of k is used to hold the logic to low logic 0 when the switch cc4071 left floating.

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 the current through the LED.


Submitted by admin on 2 July Views Read Edit View history. Logic level gates like CD and flip-flops play a vital role in digital electronics. Meaning it has four OR gate IC inside it, each of which can be cd44071 independently. The input for the gate is controlled by using a switch connected to pin A and B of the Gate.

The first is to use a NOR gate and invert the output. 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 Datasgeet respectively. The truth table for the OR gate is shown below.
