This is very rare, It has name "uncommitted emitter output type" More common is so called "open collector type output" that only pulls down to Ground. For them Joint = AND. For TTL outputs the Joint is forbidden because 0 Joint 1 = 1 Joint 0 = Smoke. | |
| Mar 20, 2017 at 19:04 | comment | added | Megidd | Thanks, I wonder if joint operator is the same as OR operator. I feel like because a joint is where two wires merge, if any of the wires is on, the joint output is on. Therefore joint is acting like OR gate. I'm not sure. | |

In addition the operators Joint and DisableInv are missing. But nothing prevents you to expand the Boolean algebra to have additional states Hi-Z, Undefined and Smoke and a new operators Joint and DisableInv | |
