I need to control one digital signal with another. I need hi-z when the control signal is low, and non-inverting buffer when the control signal is high. I'd like to do this with few parts as necessary, probably just fet based.
S_Hi S_Lo C_Hi Hi Lo C_Lo Hi_Z Hi_Z
My signals are in the 3V to 5V range.
I have a signal line that is multiplexed with a programming line. I thought the programmer would put its pins in a hi-z state, but it doesn't. Hence they hold the line low or high while not programming preventing the signal line from working properly. I have a control line that is high while the programming is working.
I'm not looking for something I'd have to order and wait a few days. It's not that big of a deal. I'm looking for a circuit I can throw together with what I have(mosfets, bjts, passives).
