OR gates with more inputs can be made up from the or any of the above ICs by cascading them together. The second will require only one IC, but only two gates datqsheet be made. The truth table for one of the four gates is shown to the right.


To visualize the output we have connected a LED to the output pin Q. Logic level gates like Dqtasheet and flip-flops play a vital role in digital electronics. From Wikibooks, open books for an open world.

Complete Technical Details can be found at the CD datasheet provided below this article. A pull down resistor of k is used to hold the logic to low logic 0 when the switch is left floating.

Submitted by admin on 2 July 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 truth table for the OR gate is shown below.

By using this site, you agree to the Terms of Use cd4701 Privacy Policy. If you have more than two inputs for your OR gate then you should look into three input and four input OR gates.

For more information about the OR gate in general, see this module. If you are looking for an IC to datzsheet logic level OR operation with two inputs, then this IC might be the right choice for you. The first is to use a NOR gate and invert the output.

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. If a is not available, there are several ways to achieve an OR gate. The output of the OR gate is called as Q. The input for the gate is controlled by using a switch connected to pin A and B of the Gate.

A selection of different manufacturers’ datasheets is given below:. The arrangement of the CMOS components is shown below:.
