[edit] merge

The Three State Logic and Tri-State Buffers should be put together and I think that the High Impedance (High-Z) shoudl be eloborated on more in the article.

I disagree. AW

Please give more information why you think so then. I put back the merge tag in the article. --Abdull 14:48, 7 March 2007 (UTC)
Done. three-state logic and tri-state buffer have been merged. --68.0.124.33 (talk) 14:41, 29 April 2008 (UTC)

[edit] table

The table showing the inputs (A,B) and the output (C) is not clear at all. I referred to this article to learn, and therefore, I am not in a position to provide a fix. Could anyone else fix this? Thanks - Todd 15:00, 9 August 2007 (UTC)

Alas, there are too many articles that seem clear to people who already know the subject, but the article doesn't help people trying to learn. This seems to be one of them -- I already know the subject, so the table seems clear to me.
If we renamed "B" to "output enable", would that clarify that the output C is connected to A when the output is enabled, but the output C is disconnected from anything when the output is disabled? --68.0.124.33 (talk) 14:41, 29 April 2008 (UTC)
If B was renamed to OE or HiZ it might make it clearer, but should also be reflected in the artwork. Jheiv (talk) 03:17, 27 May 2008 (UTC)


[edit] tristate multiplexing

The article currently mentions tristate multiplexing or Charlieplexing.

Is there some kind of tristate multiplexing other than Charlieplexing? --68.0.124.33 (talk) 14:41, 29 April 2008 (UTC)

[edit] Tri-State Logic

  • My experience is that the term in the industry is much more frequently expressed as Tri-State logic, rather than Three-State logic... Comments? Jheiv (talk) 07:48, 24 May 2008 (UTC)
  • Interestingly, both references on this page have titles with "Tri-State" rather than "Three-State"... Jheiv (talk) 07:51, 24 May 2008 (UTC)
  • I thought "Tri-state" was still a National Semiconductor trademark? Now, I have been known to go Xerox something held together with Scotch tape, but shouldn't the Wikipedia photocopy things with adhesive tape? --Wtshymanski (talk) 14:46, 24 May 2008 (UTC)
  • Most books mention both; if tri-state is a trademark as The Art of Electronics says, then it would be more encyclopedic to stick with the generic three-state. Dicklyon (talk) 01:10, 31 May 2008 (UTC)
  • I thought that "tri-state" meant "in or linking three USA states". Anthony Appleyard (talk) 11:50, 2 June 2008 (UTC)
