what is the function of data lines at 15, 1 ,10, 9 in IC 74193
Check the datasheet: http://pdf1.alldatasheet.com/datasheet-pdf/view/51050/FAIRCHILD/74193.html
They are the 4 data input lines of the counter.
You can program the counter with a preset number using these inputs, then either count up or down as needed.
