I looked for resources to find solutions to these kinds of problems online, but I couldn't find them. Please, feel free to recommend resources to study from. This is a homework question. I can't find the answers to this. I read the chapters of the book.
We need to connect outputs of circuit A to inputs of circuit B.
Circuit A has the following parameters: Powered by 5V source. V output high minimum is 2.7V. V output low maximum is 0.5V. I output high is 400uA. I output low is 16mA.
Circuit B has the following parameters: Powered by 3.3V source. V input high minimum is 2.3V. V input low maximum is 1V. I input is 1uA.
For the proposed way of connecting the circuits, A and B are compatible for low logical value, both voltage and current vise. The question is, are they compatible for high logical value? If they are not, how to make them compatible?
How would it affect compatibility for high logical level if we changed one parameter of circuit A - V output high minimum is 3.5V?
