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.
This page was last edited on 16 Decemberat Dxtasheet 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 resistor R is used to limit the current through the LED. Retrieved from ” https: The truth table for one of the four gates is shown to the right.
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.
For more information about the OR gate in general, see this module.
CD OR Gate IC Pinout, Features, Equivalent & Datasheet
The second will require only one IC, but only two gates can be made. This is discussed on this page. The arrangement of the CMOS components is shown below:. A selection of different manufacturers’ datasheets is given below:.
Policies and guidelines Contact us. 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 cd40771 method will require two ICs to implement, but a total of four gates can be made.
Datashert input for the gate is controlled by using a switch connected to pin A and B of the Gate. To visualize the output we have connected a LED to the output pin Q.

From Wikibooks, open books for an open world. If you have more than two inputs for your OR gate then you should look into three input and four input OR gates. c4071
Logic level gates like CD and flip-flops play a vital role in digital electronics. The output of the OR gate is called as Q. In other projects Wikimedia Commons. OR gates with more inputs can be made up from the or any of the above ICs by cascading them together.
A pull down resistor of k is used to hold the logic to low datashee 0 when the switch is left floating. If a is not available, there are several ways to achieve an OR gate. Submitted by admin on 2 July In other languages Add links.
Complete Technical Details can be found at the CD datasheet provided below this article. Meaning it has four OR gate IC inside it, each of which can be utilized independently. The first is to use a NOR gate and invert the output. Views Read Edit View history. The cd40711 table for the OR gate is shown below.
