Hold on to your hat. Very few people would go for an extreme 35-to-one multiplexing. For such an extreme multiplexing, it's best to just consume 35 processor pins in the first place - oops zero multiplexing needed.

You either multiplex a digit at a time - that would mean 1:5 multiplexing for this five-digit design.

Or you multiplex one segment at a time. So 1:7 or 1:8 depending on your need to involve the dot too.
