Sharing cabels for input and output

Post by Vavrik »

Hi, I am making my own latch based RAM and I want to make data input and output the same wire. Is it possible without getting the tristate error?

You need to use tri-state buffer on your outputs

Thanks, I was just confused because I thought that you cannot input on the output pin (or output on the input pin).
