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.

SN74LS08N Datasheet

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. Sign up using Email and Password. Make sure you are identifying pin 1 correctly and counting the pins in the correct direction. Once you see the outputs from the AND gates acting like they should, hook them up to the next stage.

Thanks for the advice. Yes, apparently you did next time I’ll zoom out a bit more when looking at a picture.

The 74LS08 circuit issue must be a wiring one. LarryD on Dec 29, Not the wire colour CMOS is symmetrical and you can drive loads either way. Here are the datasheets: Check with a DVM to make sure sn74ls08m have things hooked up correctly and that the voltage is correct.

This is the recommended operating current that can be sourced. I am not using any resistors.

SN74LS08N and SN74LS05N doesn’t work?

CrossRoads on Dec 29, Make sure that the inputs are within data sheet spec DVM again, at least for the DC levels- scope is better. Read times previous topic – next topic. Home Questions Tags Users Unanswered. That would tend to let the magic smoke out I meant you could make use of the breadboard bus marked with a blue line. Start creating good wiring habits.

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.
