OK, I made a mistake. I designed a PCB to use the SN74HCT138N demultiplexer. The problem is for some reason I did not realize the output was inverted and now it is causing problems. I need to find one with the same pinout that does not have inverted outputs, ie only one pin is high at a time.
I have looked all over and I can't find any that have non-inverted outputs, let alone the same pinout.
Thanks for the help,
Justin

Wow, right after I posted this I came across one, M74HC238B1R.
