For more information about the OR gate in general, see this module. Submitted by admin on 2 July This page was last edited on 16 Decemberat If a is not available, there are several ways to achieve an OR gate. The second will require only one IC, but only two gates can be made. Policies and guidelines Contact us.
The resistor R is used to limit the current through the LED. The first is to use a NOR gate and invert the output.

TL — Programmable Reference Voltage. In other projects Wikimedia Commons. 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.
Views Read Edit View history. The input for the gate is controlled by using a switch connected to pin A and B of the Gate. In other languages Add links. The first method will require two ICs to implement, but a total of four gates can be made.

This is discussed on this page. The output of the OR gate is called as Q.
A selection of different manufacturers’ datasheets is given below:. The truth table for one of the four gates is shown to the right. If you have more than two inputs for your OR gate then you should look into three input and four input OR gates.
Complete Technical Details can be found at the CD datasheet provided below this article. A pull down resistor of k is used to hold the logic to low logic 0 when the switch is left floating.
From Wikibooks, open books for an open world. 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. To visualize the output we have connected a LED to the output pin Q.
This chip is different in pinout to the TTLbut can fulfill the function of its counterpart if the wiring is modified. The truth table for the OR gate is shown below. As per the truth table shown above, when either one or both the input of the Gate is high the output will be high.
OR gates with more inputs can be made up from the or any of the above ICs by cascading them together.
The arrangement of the CMOS components is shown below:. These are available from manufacturers.
