Suppose that you have 8 output bit from the parallel port of the computer and you need to encode the output to HexDisply from 0 to 7.Extra Points for other designs??????????????????????/
how i do that???????????????????????????

 

8 bits and only 0 to 7? Sure that's not 0 - 255? What is your meaning of "HexDisplay"?

 

hi
yes from 0-7 and i mean an LED's by hexadisplay

 

Try a 7 segment driver like a 7447.

 

"Help me" as the subject is unnecessary and not helpful; you should have stated at least part of the problem in the subject line.

You should post homework questions in the Homework Help forum.

Since this is obviously homework, we can't do it for you.

However, you might look at 4000-series CMOS IC's and 74xx series TTL IC's, and find the 7-segment LED drivers. Decide which, if any, might work for your assignment.
