Hi all,
I'm working on a small little circuit, and I'm confident the logic is correct, and I believe the wiring is also correct. But it is not working, and I believe the IC I am using is to blame.
I'm using the NTE74C04 (http://www.nteinc.com/specs/7400to7499/pdf/nte74C00_20.pdf) which is a hex inverter. I have each input wired to the negative buss with a 10k Ω resistor, and I gave it a 9v power supply. The problem I am having is I can get three of the NOT gates to work, but when I set the input of a forth one to high, in output remains high. So basically only half of the chip can work at one time.
Can anyone explain this?
Thank you!
