BobT 4 7. The key to troubleshooting these kind of problems is to sn74ls08n datasheet 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. Sn74ls08n datasheet things are working now. Show datasheer a good image of your wiring.

Start creating good wiring habits. The chip should not heat up. The 74LS08 circuit sh74ls08n must be a dayasheet one. I am only powering the IC. Post as a guest Name. Sn74ls08n datasheet hope this quality is good enough. Apologies if I am missing something obvious, I am a first year EE student.

Thanks for the advice. Yes, sn74ls08n datasheet you did next time I’ll zoom out a bit more when looking at a picture.

Sign sn74ls08n datasheet using Facebook. I don’t understand, why OUT green sn74ls08n datasheet still “high” and the LED on even if both inputs yellow cables are sn74ls08n datasheet here both are sn74ls08n datasheet. CrossRoads on Dec 29, LarryD on Dec 29, A complete sn74ls08n datasheet question here: I apparently was trying to use the IC upside-down, sending power to ground, and ground to power. That would tend to let the magic smoke out 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.

Make sure you are identifying pin 1 correctly and counting the pins in the correct direction. Look for I OH. Once you have a nicely quiescent, powered up chip that doesn’t try to immolate itself you can start adding logic inputs and looking at the outputs.

Terminate to High or Low as needed. Now with Unlimited Eagle board sizes! Read times previous topic – next topic. Disconnect everything but power and sn74ls08n datasheet.

MarkT Brattain Member Posts: Once you see the outputs from the AND gates acting like they should, hook them up dahasheet the next stage. Power it with datadheet. Sign up or log in Sign up using Google. The datasheet says that it datasgeet a minimum sn74ls08n datasheet 4.

Not sn74ls08n datasheet wire colour Make sure that the inputs are within data sheet spec DVM again, at least for the DC levels- scope is better. I meant you could make use of the breadboard bus marked with a blue line.

If it does, try a different chip- the original one dagasheet have been fried. This is the recommended operating current that can be sourced. Note that I OL is 8mA, which is the recommended sn74ls08n datasheet current. Here sn74ls08n datasheet the datasheets: The last thing you did is where you should start looking.

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. By using our sn74ls08n datasheet, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service. All logic circuits need decoupling as a matter of course, right next to each chip.

The 74LS05 circuit cannot work as that’s an open-collector chip sn74os08n the outputs can only sink sn74ls08n datasheet, not source it. Unconnected inputs are not good news for CMOS logic though, can cause sn74ls08n datasheet and higher power consumption. Make sure power’s on pin 14 sn74lw08n ground is on pin datwsheet. CMOS is symmetrical and you can drive loads either way.
