The input for the gate is controlled by using a switch connected to pin A and B of the Gate.
These are available from manufacturers.
Views Read Edit View history. The arrangement of the CMOS components is shown below:. As per the truth datasehet shown above, when either one or both the input of the Gate is high the output will be high. For more information about the OR gate in general, see this module.
A selection of different manufacturers’ datasheets is given below:. 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 truth table for the OR gate is shown below. This is discussed datazheet this page.
The second will require only one IC, but only two gates can be made. If a is not available, there are several ways to achieve an OR gate. The datasheef 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 output of the OR gate is called as Q. Logic level gates like CD and flip-flops play a vital role in digital electronics.

Complete Technical Details can be found at the CD datasheet provided below this article. The resistor R is used to limit the current through the LED. The first method will require two ICs to implement, but a total of four gates can be made. Submitted by admin on 2 July TL — Programmable Reference Voltage.
