CPU 3.3V -> 5V -> 3.3V

[x12253@gmail.com]

Ma to inspirovalo na otazku ohladom jedneho projektu:

Co spravit ked potrebujeme do 3,3V logiky pripojit 5V procesor ??
Je to dev.board doska a chceme tam na otestovanie vlozit 386dx proc.
Napadlo ma pouzit nejake cpld pole s 3,3V/5V compatible IOs. Pinov je
totizto trocha dost...

Nemate s tym niekto skusenost?
