Hey there,
I'm building an experimental 1-digit counter w/ 74LS90, but there's a small problem: I could only hook it up to show BCDs successfully, but not when I connect it with the 74LS47.
The display latches up with gibberish when I connect it to +5V and worse, it didn't budge when the counter is counting.
What could have happened to the decoder?
