Hi!!

If anybody may help me, I will be thanks a lot.

The features circuit are as following:

1.- It must to be programmed of 0000 to 1001.
2.- It must to be 10 steps ( 0 - 9 ).
3.- It must to have a load pin ( to load the program ).
4.- It must to count up/down.
5.- When it reach state 0000, stop it.
6.- That I can stop the count any time and visualize it. ( 7 segment display)
7.- It must to have a reset button for load the program again.
8.- It must to have a start button, ( when I want).

I found the 74LS192 integrated circuit, BUT I can't to find it in Chile.

If anybody can to get it, say me how and where. Please.
