<div class=""><span style="font-family: Arial; font-size: small;" class="">I'm currently waist
deep in a digital logic design problem, and I will need a 4-bit decoder and a
4-bit encoder. For the decoder, I will use CD4514 or equivalent.
However, I'm not finding any comparable chip for the encoder. At this
point, I am resigned to making my own 4-bit encoder from two 3-bit encoders
(CD4532) and a quad OR gate (CD4071).</span></div>

Maybe use a PAL (like a 22V10) if you have the tools for that. Or if speed is not an issue, just use a tiny microcontroller.</div><div><br class=""></div><div>Ben</div><div><br class=""></div></div></body></html>
