<p>You could probably do this with two 4532 8-bit priority encoders.<br>
</p>
<p>Could even do it with a diode matrix if space was not an issue :)<br>

<div>There’s tons of 10 to 4 encoders, but I don’t see 16 to 4
either. What VCC range and speed do you need? 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>
