Submitted by admin on 2 July OR gates with more inputs can be made up from the or any of the above ICs by cascading them together. Policies and guidelines Contact us.
These are available from manufacturers. The arrangement of the CMOS components is shown below:. In other projects Wikimedia Commons.
The first is to use datashee NOR gate and invert the output. The input for the gate is controlled by using a switch connected to pin A and B of the Gate.
Meaning it has four OR gate IC inside it, each of which can be utilized independently. Retrieved from ” https: Logic level gates like CD and flip-flops play a vital role in digital electronics.
This chip is different in pinout to the TTLbut can fulfill the function of its counterpart if the wiring is modified. The second will require only one IC, but only two gates can be made.
Datasheef output of the OR gate is called as Q. This is discussed on this page. For more information about the OR gate in general, see this module. A selection of different manufacturers’ datasheets is given below:.
If you have more than two inputs for your OR gate then you should look into three input and four input OR gates. To visualize the output we have connected a LED to the output pin Q. From Wikibooks, open books for an open world. The logic OR operation is datasheer 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. A pull down resistor of k is used to hold the logic to low datashwet 0 when the switch is left floating.
This page was last edited on 16 Datashretat The resistor R is used to limit the current through the LED. In other languages Add links. 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. If a is not available, there are several ways to achieve an OR gate.
The truth table for one of the four gates is shown to datssheet right. The first method will require two ICs to implement, but a total of four gates can be made.
