The dtaasheet for the gate is controlled by using a switch connected to pin A and B of the Gate. Submitted by admin on 2 July The truth table for the OR gate is shown below. Views Read Edit View history. This page was last edited on 16 Decemberat Meaning it has four OR gate IC inside it, each of which can be utilized independently.
A selection of different manufacturers’ datasheets is given below:. 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. 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. In other projects Wikimedia Commons. 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 datasneet OR gates.
Logic level gates like CD and flip-flops play a vital role in digital electronics. For more information about the OR gate in general, see this module. If a is not available, there are several ways to achieve an OR gate.
The first is to use darasheet NOR gate and invert the output. The first method will require two ICs to implement, but a total of four gates can be made.

In other languages Add links. The arrangement of the CMOS components is shown below:. 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. The resistor R is used to limit the current through the LED.
From Wikibooks, open books for an open world. Policies and guidelines Contact us. This chip is different in pinout to the TTLbut can fulfill the function of 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.
To visualize the output we have connected a LED datahseet the output pin Q. The output of the OR gate is called as Q.
These are available from manufacturers. OR gates with more inputs can be made up from the or any of cd40711 above ICs by cascading them together.
This is discussed on this page. Retrieved from ” https: The second will require only one IC, but only two gates can be made.
