Cant make 7segment display run using 74LS47 IC

  1. Feb 6, 2009 #1
    would a 7 segment display show numbers if you only use a 74LS47 ic only?
    i connected it all the pins right according to the schematics 7447.gif

    the 7 segment display is connected right in pins 15-9 in 7447 ic and the pins 7,1,2 & 6 i used as 4 bit binary input, so when i input 0101 which is 5 no light come out from the 7 segment, is there anything wrong in my connections?
