I use a lot of integrated circuits of various types. However, I have trouble testing them. I've already looked for an IC test, but I have not seen it anywhere. How to proceed for the tests?
In fact, each integrated circuit is a complete circuit and not a component. Thus, as we already know, what we try to test is the circuit and not the component. We can not test an individual component within the IC. Since each circuit has a different function, there is no circuit that tests all. What you can do is to set up a test circuit for a more common integrated circuit such as 555, 741, 4017, 7805, etc. There are two common procedures for testing an IC: The first is the comparative measure of resistance between the terminals. The measured resistance between the terminals of the suspected IC is compared with a good IC. If we find differences, the component is bad. Another procedure is to measure the voltages in the working IC. The values of these voltages must be obtained in the diagram of the apparatus.
