Data sheet acquired from Harris Semiconductor. SCHSD – Revised August CDB. Quad 2-Input OR Gate. CDB. This datasheet has been downloaded from: This file is the datasheet for the following electronic components: CD – ?. CD is a Dual Input OR Gate with Quad package, i.e. it has four OR gate IC inside it, each of which can be utilized independently.

The truth eatasheet for the OR gate is shown below. In other languages Add links. This datashert discussed on this page. The first method will require two ICs to implement, but a total of four gates can be made. From Wikibooks, open books for an open world. This page was last edited on 16 Decemberat A selection of different manufacturers’ datasheets is given below:. If a is not available, there are several ways to achieve an OR gate.

The arrangement of the CMOS components is shown below:. The truth table for one of the four gates is shown to the right.
Retrieved from ” https: The first is to use a NOR gate and invert the output. Complete Technical Details can be found at the CD datasheet provided below this article. Views Read Edit View history. Submitted by admin on 2 July A pull down resistor of k is used to hold the logic to low logic 0 when the switch is left floating.
As per the truth table shown above, when either one or both the input of the Gate is high the output will be high. If you have more than two inputs for your OR gate then dstasheet should look into three input and four input OR gates.
The second will require only one IC, but only two gates can be made. This datasbeet is different in pinout to the TTLbut can fulfill the function of its counterpart if the wiring is modified. The logic OR operation is very simple, since this is a two input Dxtasheet gate we will have only two inputs which is A and B respectively. TL — Programmable Reference Voltage. The output of the OR gate is called as Q. In other projects Wikimedia Commons.
These are available from manufacturers.
For more information about the OR gate in general, see this module. OR gates with more inputs can be made up from the or any of the above ICs by cascading them together.
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. Datashheet level gates like CD and flip-flops play a vital role in digital electronics.
To visualize the output we have connected a LED to the output pin Q.
