Author Topic: [HELP] - 74ls193 Binary Counter (Read 1169 times)

FarProd · « **on:** February 07, 2012, 10:11:23 AM »

Paano po ba i design 74ls193 na mag ka-count up and count down ang 74ls193 Binary Counter to Binary Coded Decimal (BCD) 00 - 99 and 99-00?

any help..

Sana eh, mabigyan niyo ako ng schematic diagram... Thanks a lot!

eto yung data sheet ng 74193

[

Pin 16= +source
8= - source
2,3,6,7= to Display
4 or 5= Clock pulse

pag count down sa 4
pag count up sa 5

I miss the time when I played with logic gates and counters.
Anyway parang hindi masyadong mahirap yan dahil BCD lang daw ang output.
So no need na ang 7447 at 7 segments.
Ok na yang binigay ni jjepoy. Hindi yan manual up counter.
Gawan mo lang TS ng two way switch sa UP/DN input ng 193 sa one's digit.
Then detect mo ang 0 to 9 transistion sa CO pin ng ones digit connect mo sa DN pin ng tens digit.
You may need to invert the signal, kaw na bahala mag experiment.

Sa down count naman, since you were asked to use a 74LS193 binary counter, you need to detect the "borrow" signal and load the value "9" to the 74LS193 counter.

Ay so sory TS, mali pala ang sabi ko.
Detect 0-9 transition sa BO pin.
I stand corrected.
Thanks sir motion.
