Is there really a voltage level that is exactly between 0 and 1?

I can imagine a system like this that would have far less problems:
0V means "0"
5V means "1"
When the level goes from 0V to 5V, at 3V the bit flips to "1".
When the level goes from 5V to 0V, at 2V the bit flips to "0".

Does anyone know how things work in the MSX ICs?
