Like the other two most popular answers, your 7 segment display needs to be connected to the 7447 properly 7447 Outputs to Seven-segment display inputs, a-to-a, b-to-b., g-to-g . This allows a smaller 4-bit binary number half a byte to be used to display all the denary numbers from 0 to 9 and by adding two displays together, a full range of numbers from 00 to 99 can be displayed with just a single byte of eight. This is my first post so please bare with I'm currently working on building a 7 segment display circuit using 2 6 position DIP switches to a 4 bit adder 7483 , to a 7 segment decoder 7447 , then through an inverter chip 7404 then finally to my 7 Segment Display common cathode---hence the inverters .
