Click to expand...

You may look for GAL type of IC or PIC could do it...

Another simple way to do it (which was quite common years ago) is to use an EPROM.

Looks like you want a 4532 8-bit priority encoder. (Motorola/ON Semi part number MC14532B.) Here's a link to a datasheet:https://www.electro-tech-online.com/custompdfs/2005/06/MC14532B-DPDF.pdf

ok, great.. thx..

is there 32x5 encoder ? if yes, where i can find the datasheet / part number?
or there is no 32x5 encoder?

or what i need is to cascade some encoders to have 32x5 ?
(like 4532 datasheet page 7)



thx
