As per the truth table shown above, when either one or both the input of the Gate is high the output will be high. This page was last edited on 16 Decemberat The truth table for the OR gate is shown below.
If a is not available, there are several c4d071 to achieve an OR gate.
The output of the OR gate is called as Q. A pull down resistor of k is used to hold the logic to low logic 0 when the switch is left floating. In other languages Add links.
The input for 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. Vatasheet selection of different manufacturers’ datasheets is given below:. The first is to use a NOR gate and invert the output. 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.
OR gates with more inputs can be made up from the or any of the above ICs by cascading them together. These are available from manufacturers.
The truth table for one of the four gates is shown to the right. From Wikibooks, open books for an open world.

To visualize the output we have connected a LED to the output pin Q. The logic OR operation is very simple, since this is a two input OR xd4071 we will have only two inputs which is A and B respectively.
Meaning it has four OR gate IC inside it, each of which can be utilized independently. Views Read Edit View history. This is discussed on this cd40711. TL — Programmable Reference Voltage.
CD OR Gate IC Pinout, Features, Equivalent & Datasheet
Complete Technical Details can be found at the CD datasheet provided below this article. If you have more than two inputs for your OR gate then you daatasheet look into three input and four input OR gates. Policies and guidelines Contact us. Logic level gates like CD and flip-flops play a vital role in digital electronics.
Retrieved from ” https: Datasheft other projects Wikimedia Commons. The second will require only one IC, but only two gates can be made. The arrangement of the CMOS components is shown below:. The first method will require two ICs to implement, but a total of four gates can be made.
This chip is different in pinout to the TTLbut can fulfill the function of its counterpart if the wiring is modified.
