Hi friends,
I have a question about bus termination (transmission line theory).
I have been wondering if it is possible to solve the long line problem of needing termination resistors by splitting the wires in multiple bits by adding buffer IC's in between the parts. For example using 74HC244 buffers to split a long line so that the remaining lengths are so small that they don't need terminating resistors.
This seems to make sense to me because from what I understand the problem only occurs in between IC's.
Is this correct or wrong?
Is it possible that even by adding the buffers, that when they are open the line is still long? Or would this work?
Thanks a lot!
