Retrieved from ” https: For more information about the OR gate in general, see this module. This page was last edited on 16 Decemberat A selection of different manufacturers’ datasheets is datsheet below:.

The input cd401 the gate is controlled by using a switch connected to pin A and B of the Gate. The resistor R is used to limit the current through the LED. If you have more than two inputs for your OR gate then you should look into three input and four input OR gates. In other projects Wikimedia Commons.

Practical Electronics/IC/4071

Meaning cd4701 has four OR gate IC inside it, each of which can be utilized independently. 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.


Views Read Edit View history. The second will require only one IC, but only two gates can be made. This is discussed on this page.

If a is not available, there are several ways to achieve an OR gate. The arrangement of the CMOS components is shown dataeheet. Logic level gates like CD and flip-flops play a vital role in digital electronics. In other languages Add links. The output of the OR gate is called as Q.

Policies and guidelines Contact us. The first method will require two ICs to implement, but a total of four gates can be made.

From Wikibooks, open books for an open world. To visualize the output we have connected a LED to the output pin Q. These are available from manufacturers. The truth table for one of the four gates is shown to the right.

Submitted by admin on 2 July If you are looking for an IC to perform logic level OR operation with two inputs, then this Datashdet might be the right choice for you. A pull down resistor of k is used to hold the logic to low logic 0 when the switch is left floating.


TL — Programmable Reference Voltage. This chip is different in pinout to the TTLbut can fulfill the function datashwet its counterpart if the wiring is modified. As per the truth table shown above, when either one or both the input of the Gate is high the output will be high.

Complete Technical Details can be found at the CD datasheet provided below this article. The truth table for the OR gate is shown below.

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