I have an 74LS47 IC.
I connected each of the data pins.
I connected the 7 segment display's +5V and ground.
I then connected the 5V on the IC but hadn't done ground yet.
The 7 segment display lit up.
When I connect the ground and then put 5V into one of the data pins, nothing happens.
Have I screwed it?
