Other Parts Discussed in Thread: TMUX1072, SN74HC257

Hi,

I am currently using TMUX1072DGSR as the 2:1 MUX part. Do you have any 2:1 Mux part with the tristate option?

Regards.

Pull /OE high. Or what do you mean with "tristate"?

Hi Abhijith,

The TMUX1072 is an analog switch so there isn't defined outputs as you'd find in a digital multiplexer - most of TI's switches/multiplexers are analog so they they have a continuous band of outputs within the operating range and the switch can be open, closed, or high impedance -> but the switch itself is passive and doesn't drive anything.

That being said - I am adding in our Logic Product line because I believe they may have a few digital multiplexers that could potentially work- but it may be limited.

Best,

Parker Dodson

If you're looking for a digital mux, you could use SN74HC257, which has 3-state outputs.
