| Jul 13, 2023 at 22:03 | comment | added | periblepsis | Sgg8, @Dave 's comment is the first thing that comes to my mind. ECL, first and foremost. In fact, I was doing a page search to find ECL when reading this page to see if anyone had mentioned it, already. That's when I found his comment. | |
| Jul 13, 2023 at 21:07 | comment | added | Dave Tweed | Voltage-mode logic is just one broad class of logic that is commonly used. But there's also current-mode logic -- ECL is just one example. | |
| Jul 13, 2023 at 20:15 | comment | added | user263983 | Resistors are usually used to protect output from shortage. For instance, the signal goes through connector. Low value is used. Sometimes it is for suppress spikes, caused by induction on long conductor. | |
| Jul 13, 2023 at 20:07 | comment | added | Jeroen3 | There is some logic, for industrial (wired) automation there is IEC 61131-2 that specifies a minimum amount of current for improved noise immunity. | |

| Jul 13, 2023 at 18:09 | comment | added | Math Keeps Me Busy | "I undestand that most logic gates' inputs are directly connected to a base of a transistor." Well, in TTL and related families, the input is usually connected to the emitter of a transistor, not the base. | |
