OR gates with more inputs can be made up from the or any of the above ICs by cascading them together. The truth table for one of the four gates is shown to the right. The resistor R is used to limit the current through the LED.
The output of the OR gate is called as Q. A selection of different manufacturers’ datasheets is given below:. The truth table for the OR gate is shown below.
Logic level gates like CD and flip-flops play a vital role in digital electronics. Policies and guidelines Contact us.
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. In other languages Add links. Meaning it has four OR gate IC inside it, each of which can be utilized independently. The first method will require two ICs to implement, but a total of four gates can be made.

The input for the gate is controlled by using a switch connected to pin A and B of the Gate. Retrieved from ” https: From Wikibooks, open books for an open world.
If a is not available, there datashset several ways to achieve an OR gate. 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 chip is different in pinout to the TTLbut can fulfill the function of its counterpart if the wiring is modified.
If you are looking for an IC to perform logic level OR operation with two inputs, then this IC datashet be the right choice for you. In dc4071 projects Wikimedia Commons.

To visualize the output we have connected a LED to the output pin Q. A pull down resistor of k is used to hold the logic to low logic 0 when the switch is left floating.
