Disconnect everything but power and ground. I am only powering the IC. Email Required, but never shown. Make sure power’s on pin 14 and ground is on pin 7. Sign up using Facebook.
Thanks for the advice. Yes, apparently you did next time I’ll zoom out a bit more when looking at a picture.

This is the recommended operating current that can be sourced. I am not using any resistors.
SN74LS08N and SN74LS05N doesn’t work?
The datasheet says that it requires a minimum of 4. Note that I OL is 8mA, which is the recommended sink current.

A complete newbie question here: I apparently was trying to use the IC upside-down, sending power to ground, and ground to power. Post as a guest Name.
Apologies if I am missing something obvious, I am a first year EE student. The key to troubleshooting these kind of problems is to break them down to their essentials and add stages only after what you start with is working properly. I’m not using any of the AND gates. BobT 5 7. The chip should not heat up.
The last thing you did is where you should start looking. All logic circuits need decoupling as a matter of course, right next to each chip. You would fare better to use modern CMOS families like 74HC, so 74HC08 and gates, 74HC14 not gates everyone uses the ’14 because it has schmitt-trigger inputs which are very useful for signal conditioning.
