Vyvod 6 je vystup, vyvod 7 -Voe, je povoleni vystupniho zesilovace,
t.j. je-li v 0, tak zesilovac normalne pracuje. Nazev toho pinu
je "Output enable". Jinak jde o velmi kvlitni optocleny,
ktere pouzivame v prevodnicich RS232-RS422. Pri pouziti techto optoclenu
je treba dat obzvlastni pozor na dobrou filtraci napajeciho napeti, t.j.
kondenzator tesne u soucastky u obou systemu - jinak to kmita.
