hi mates , i am new here and i have a little questions ... :)

i want to make on breadboard a logic circuit which shows on a 7 segment display
the hexademic. and the hexademic will be gived with BCD and Dip-switcth.. And it will be done with help off multiplects and -demu..

i search it and ,i think that i will use 74ls47 , but this will show me from 0 to 9 , the others ,a,b,c d,e,f? i will use a hex converter after th 7447 ?

Hi,

Have a look to 9368 ...

or program a 16F84 as a transcoder !!!

first time i show this but it's very good for what i search , in the logic diagramm what is latch ?
and which is the 1 of 16 decoder ?

with 7447 there isn't a way to make it ?

i can't find the 9368 to buy it , isn't a different way to make the circuit with 74ls 47 ?
