Nov 6, 2023 at 16:59 | comment | added | Ben Voigt | "You don't want the information on the bus to be read by every unit at the same time" But this is what tri-state buffers actually lead to. Because the three states are "Output Low, Output High, and Input". Removing loads from the bus is valuable, but has little to do with "tri-state output", the topic of the question. | |

Nov 11, 2019 at 13:46 | comment | added | MCG | @user1999 It depends what you have connected to it, whether it is On/Off or Input/Output. It depends on the application. There isn't much advantage to a tri-state ON/OFF switch. As for inputs and outputs, I'll add an example to the answer | |
Nov 11, 2019 at 13:10 | comment | added | user1999 | @MCG You mean ON is INPUT and OFF is OUTPUT? Why do you call them as input and output? Aren't all states output? Here they call them output i.sstatic.net/LutlM.png Could you clarify that as well? And if possible where in practice is this tri state used? Can we name any ? | |
