CD OR Gate IC Pinout, Features, Equivalent & Datasheet
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. From Wikibooks, open books for an open world.
Complete Technical Details can be found at the CD datasheet provided below this article. For more information about the OR gate in general, see this module.
If you have more than two inputs for your Ce4071 gate then you should look into three input and four input OR gates. This is discussed on this page. TL — Programmable Reference Voltage.
These are available from manufacturers. This chip is different in pinout to the TTLbut can fulfill the function of its counterpart if the wiring is modified. This page was last edited on 16 Decemberat As per the truth table shown above, when either one datadheet both the input of the Gate is high the output will be high.

A selection of different manufacturers’ datasheets is given below:. The first method will require two ICs to implement, but a total of four gates can be made. Meaning it has four OR gate IC inside it, each of which can be utilized independently.
A pull down resistor of k is used to hold the logic to low logic 0 when the switch is left floating. The truth table for the OR gate is shown below.
The resistor R is used to limit the current through the LED. The truth table for one of the four gates is shown to the right.

Retrieved from ” https: 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. Logic level gates like CD and flip-flops play a vital role in digital electronics.
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 can be made.
