See my previous post for output driving currents and suggestion. Email Required, but never shown. MarkT Brattain Member Posts: Unconnected inputs are not good news for CMOS logic though, can cause oscillations and higher power consumption. Read times previous topic – next topic. I meant you could make use of the breadboard bus marked with a blue line. I hope this quality sn74ls08h good enough. 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.

Make sure you are identifying pin 1 correctly and counting the pins in the correct direction. If it does, try a different chip- the original one may have been fried. Once you have a nicely quiescent, datasheeet up chip that doesn’t try to immolate itself you can start adding logic inputs and looking at the outputs.

Now with Unlimited Eagle board sizes! Thanks for the advice. You would fare better to use dn74ls08n 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. The 74LS08 circuit issue must be a wiring one.

integrated circuit – Why is my SN74LS08N overheating? – Electrical Engineering Stack Exchange

I don’t understand, why OUT green cable still “high” and the LED on even if both inputs yellow cables are off here both are on. Note that I OL is 8mA, which is the recommended sink current.

Post as a guest Name. All logic circuits need decoupling as a matter of course, right next to each chip.

Look for I OH. Once you see the outputs from the AND gates acting like sn74lls08n should, hook them up to the next stage.

I apparently was trying to use the IC upside-down, sending power to ground, and ground to power. Terminate to High or Low as needed.

You are lacking decoupling caps on your chips BTW – don’t get into that bad habit, nF ceramic for each chip is a good starting point. I am only powering the IC. Here are the datasheets: Datasehet everything but power and ground.

Make sure power’s on pin 14 and ground is on pin 7. Power it with 5V. Sign up using Email and Password. A complete newbie question here: Start creating good wiring habits. LarryD on Dec 29, Glad things are working now. Sign up or log in Sign up using Google.

Sign up using Facebook. I’ve got some logic gates from Texas Instruments and would like to understand why the left circuit doesn’t work while the right one works well and. Not the wire colour BobT 5 7. CMOS is symmetrical and you can drive loads either way.

The chip should not heat up. The datasheet says that it requires a minimum of 4. Show us a good image of your wiring. Apologies if I am missing something obvious, I am a first year EE student.

The 74LS05 circuit cannot work as that’s an open-collector chip – the outputs can only sink current, not source it.
