For more information about the OR gate in general, see this module. This page was last edited on 16 Decemberat TL — Programmable Reference Voltage. The resistor R is used to limit the current through the LED. This chip is different in pinout to the TTLbut can fulfill the function of its counterpart if the wiring is modified. If a is not available, there are several ways to achieve an OR gate.
The first is to use a NOR gate and invert the output. To visualize the output we have connected a LED to the output pin Q. Retrieved from ” https: Meaning it has four OR gate IC inside it, each of which can be utilized independently.
Policies and guidelines Contact us. The output of the OR gate is called as Q. A selection of different manufacturers’ datasheets is given below:.
If you have more than two inputs for your OR gate then you should look into three input and four input OR gates. 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.

The input for the gate is controlled by using a switch connected to pin A and B of the Gate. The truth table for the OR gate is shown below. OR gates with more inputs can be made up from the or any of datasjeet above ICs by cascading them together. Complete Technical Details can be found at the CD datasheet provided below this article.
CD OR Gate IC Pinout, Features, Equivalent & Datasheet
The arrangement of the CMOS components is shown below:. The first method will require two ICs to implement, but a total of four gates can be made. Logic level gates like CD and flip-flops play a vital role in digital electronics.
This is discussed on this page. Submitted by admin on 2 July 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. From Wikibooks, open books for an open world. The second will require only one IC, but only two gates can be made.

A pull down resistor of k is used to hold the logic to low logic 0 when the switch is left floating.
