**I asked an admin where to post this topic, because i wasnt sure if it should go in the hw forum or not, and was told to post here. Hello. I am taking a beginning circuits class this summer and every homework assignment is accompanied by a simple thought provoking essay (about a page). Yesterday, this was our topic: "Data bus tristate transceiver. What is it? How does it work? Why use one?" I know what data busses are, and i know what a transceiver is. I assume tristate refers to the outputs on the transceiver, but i dont really understand what it means. Running a search for permutations of "data bus tristate transceiver" didnt result in anything a lay person could easily understand. Is this a specific type of transceiver, or a generalization of all tristate data busses? I read the Wikipedia but obviously thats no credible source. I guess my issue with the assignment is finding reliable information that isnt overly technical. I was hoping one of the EE's out there could point me in the right direction as to where to start my research. Thank you in advance.
