They don't have to be.  E.g., see this link:

https://en.wikipedia.org/wiki/Ternary_computer

It's just that most electronic circuits are designed for binary logic
for computing.  They don't use ternary logic.  This should not be
confused with tri-state logic.  The latter has 3 electrical levels,
but only two are used for representing digits, i.e., binary logic.
