    Hello. I am trying to implement a tri-state buffer on a bread board. Is there a 74 series IC that is a tristate buffer? How can I do this? Thank you very much.

    Also 74x365, 74x366, 74x367, & 74x368

    BTW Caveman, that's a pretty good list

    Yeah, just googled it and wikipedia popped up. Never seen it before, but I'll use it from now on.

    Thanks for the info. Quick question though. What is the difference between these tri state buffers and the transmission gates that use n and pmos transistors to pass data through? I am talking specifically about the CD4016BE analog switches. Are they equivalent?

    These tri-state buffers drive logic levels (low or high only) through when they drive. The CD4016 is an anlalog switch. It passes analog straight through.
