 It is impossible to get 56 bits of information directly from 8 trits (the term for a base-3 character, as the pins are 3-state) of information, as 8 trits fundamentally comprises 8 log23, or about 12.7 bits of information, which falls far short of the 56 bits required to turn all 56 LEDs on or off in any arbitrary combination.Instead, the human eye must be fooled by use of multiplexing.Only one 7-segment display, one set of 7 LEDs can be active at any time.
