7400 competition entry: Ternary base-3 electronics using 74HC4052

Posted on Friday, October 21st, 2011 in 7400 contest by DP

Shaos entered a (balanced) ternary electronic device based on the 74HC4052 into the Open 7400 Logic Competition. Ternary Balanced ternary is a base-3 number system, instead of bits (0, 1, 10, 11, etc), this counts in trits (-1, 0, 1):

The “Test bed” consists of 20 sockets for testing “our standard ternary components“. For ternary full adder only 7 sockets are used…

+5 volts is positive ternary value (P) – GREEN LED, 0 volts is zero ternary value (O) – OFF LED, -5 volts is negative ternary value (N) – RED LED

    Correction – it’s “Balanced Ternary System”, so it is not 0,1,2, but -1,0,+1 – for example +1 +1 +1 (PPP) is 9+3+1=13, and -1 0 +1 (NOP) is -9+1=-8)
