OR gates with more inputs can be made up from the or any of the above ICs by cascading them together. Views Read Edit View history. daatasheet

Complete Technical Details can be found at the CD datzsheet provided below this article. The input for the gate is controlled by using a switch connected to pin A and B of the 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. If you have more than two inputs for your OR gate then you should look into three input and four input OR gates.

The second will require only one IC, but only two gates datsaheet be made. By using this site, you agree to the Terms of Use and Privacy Policy. The output of the OR gate is called as Q.

Retrieved from ” https: The truth table for one of the four gates is shown to the right. The first method will require two ICs to implement, but a total of four gates can be made. If a is not available, there are several ways to achieve an OR gate. Submitted by admin on 2 July Meaning it has four OR gate IC inside it, each of which can be utilized independently. 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.

TL — Programmable Reference Voltage.

From Wikibooks, open books for an open world. Policies and guidelines Xd4071 us. Logic level gates like CD and flip-flops play a vital role in digital electronics. The truth table for the OR gate is shown below. The arrangement of the CMOS components is shown below:.


As per the truth table shown above, when either one or cd401 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.

These are available from manufacturers. The first is to use a NOR gate and invert the output. A selection of different manufacturers’ datasheets is given below:.

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. This is discussed on this page. In other projects Wikimedia Commons. The resistor R cd40771 used to limit the current through the LED.
