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. Complete Technical Details can be found at the CD datasheet provided below this article.
OR gates with more inputs can be made up from the or any of the above ICs by cascading them together. TL — Programmable Reference Voltage. The first method will require two ICs eatasheet implement, but a total of four gates can be made.
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. The truth table for one of the four gates is shown to the right.
The first is to use a NOR gate and invert the output. The datsaheet for the gate is controlled by using a switch connected to pin A and B of the Gate. If you have more than two inputs for your OR gate then you should look into three input and four input OR gates. Meaning it has four OR gate IC inside it, each of which can be utilized independently.
Policies and guidelines Contact us. This chip is different in pinout to the TTLbut can fulfill the datasehet of its counterpart if the wiring is modified. The resistor R is used to limit the current through the LED. Submitted by admin on 2 July The second will require only one IC, but only two gates can be made.
To visualize the output we have connected a LED to the output pin Q. A selection of different manufacturers’ datasheets is given below:. For more information about the OR gate in general, see this module. The output of the OR gate is called as Q. From Wikibooks, open books for an open world.

If a is not available, there are several ways to achieve an OR gate. Logic level gates like CD and flip-flops play a vital role in digital electronics.

The arrangement of the CMOS components is shown below:. A pull down resistor of k is used to hold the logic to low logic 0 when the switch is left floating. If you are cd471 for an IC to perform logic level OR operation with two inputs, then this IC might be the right choice for you. Retrieved from ” https:
