A pull down resistor of k is used to hold the logic to low logic 0 when the switch is left floating. To visualize the output we have connected a LED to the output pin Q.

Policies and guidelines Contact us. From Wikibooks, open books for an open world. Retrieved from ” https: The output of the OR gate is called as Q.

Views Read Edit View history. Submitted by admin on 2 July The logic OR operation is very simple, since this is a two input OR gate we will have daatasheet two inputs which is A and B respectively. The first method will require two ICs to implement, but a total of four gates can be made.

If a is not available, there are several ways to achieve an OR gate. Complete Technical Details can be found at the CD datasheet provided below this article. The input for the gate is controlled by using a switch connected to pin A and B of the Gate. The second will require only one IC, but only two gates can be made.

Practical Electronics/IC/4071

If you are looking for dattasheet IC to perform logic level OR operation with two inputs, then this IC might be the right choice for you.

The first is to use a NOR gate and invert the output. The arrangement of the CMOS components is shown below:. By using this site, you agree to the Terms of Use and Privacy Policy.

Meaning it has four OR gate IC inside it, each of which can be utilized independently. Logic level gates like CD and flip-flops play a vital role in digital electronics. TL — Programmable Reference Voltage. This page was last edited on 16 Decemberat This chip is different in pinout to the TTLbut can fulfill the function of its counterpart if the wiring is modified. In cd401 projects Wikimedia Vd4071. 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. If you have more than two inputs for your OR gate then you should look into three input and four input OR gates.

A selection of different manufacturers’ datasheets is given below:. OR gates with more inputs can be made up from the or any of the above ICs by cascading them together. This is discussed on this page.

These are available from manufacturers. The truth table for one of the four gates is shown to the right. The resistor R is used to limit the current through the LED. The truth table for the Dahasheet gate is shown below. In other languages Add links.
