How it works
This is pretty much just a string of inverters to try to make a delay line or ring oscillator. Also there's an xor gate on the bidir pins, maybe test as a mixer?
How to test
Basic DC logic on the first couple pins, couldn't describe any way other than the logic itself OUT1 = IN3 ? (IN0 & IN1) : IN2 OUT0 and OUT2 are both !OUT1 and the rest of the OUT<n>s should be the same as OUT1 D2 = D0 ^ D1
External hardware
Nothing specific, switches or digital in to the input
IO
| # | Input | Output | Bidirectional |
|---|---|---|---|
| 0 | IN0 | OUT0 | D0 |
| 1 | IN1 | OUT1 | D1 |
| 2 | IN2 | OUT2 | D2 |
| 3 | IN3 | OUT3 | D3 |
| 4 | IN4 | OUT4 | |
| 5 | IN5 | OUT5 | |
| 6 | IN6 | OUT6 | |
| 7 | IN7 | OUT7 |
