Why would a troubleshooting tech need to know about each Logic IC chips, Logic Threshold Voltage Levels?

What kind of troubleshooting would a test technician be doing to have to know the logic threshold voltage levels?

When are they used for what use?


Here is a Chart of them:

Because they're not all the same

They would be troubleshooting a problem. Probably, but not definitely, related to odd and unexpected state transitions, or the failure to perform state transitions as expected.

When are they used for what use?
I would advise you to learn about these threshold voltages and what they mean.

I'm not going to tell you and I'm not even going to look up a link for you because you have a history of ignoring us.

edit: and I feel I'm COMPLETELY justified in closing this thread now I visit the linked page. It explains the answer to your final question. It also reinforces the fact that you are willfully ignorant.
