This page was last edited on 16 Decemberat This is discussed on this page. As per the truth table shown above, when either one or both the input of the Gate is high the output will be high. The output of the OR gate is called as Q. The truth table for one of the four gates is shown to the right.
The arrangement of the CMOS components is shown below:. Meaning it has four OR gate IC inside it, each of which can be utilized independently. OR gates with more inputs can be made up from the or any of the above ICs by cascading them together.

To visualize the output we have connected a LED to the output pin Q. The first is to use a NOR gate and invert the output. Submitted by admin on 2 July In other projects Wikimedia Commons. From Wikibooks, open books for an open world. The resistor R is used to limit the current through the LED.
If a is not available, there are several ways to achieve an OR gate.
If you have more than two inputs for your OR gate then you should look into three input and four input OR gates. Views Read Edit View history. This chip is different in pinout to the TTLbut can fulfill the function of its counterpart if the wiring is modified.
The truth table for the OR gate is shown below. A selection of different manufacturers’ datasheets is given below:. A pull down resistor of k is used to hold the logic to low logic 0 c4071 the switch is left floating. Retrieved from ” https: 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 input for the gate is controlled by using a switch connected to pin A and B of datadheet Gate. 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. TL — Cd4701 Reference Voltage. The second will require only one IC, but only two gates can be made.
