I am only powering the IC. Show us a good image of your wiring. You would fare better to use sn74ls08n datasheet CMOS families like 74HC, so 74HC08 and gates, 74HC14 not gates everyone dztasheet the ’14 sn74ls08n datasheet it has schmitt-trigger inputs which are very useful for signal conditioning.

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

Sign up using Facebook. The datasheet says that sn74ls08n datasheet requires a minimum of 4. Sn74l08n creating good wiring habits. That would tend to let the magic smoke out Questions Tags Users Badges Unanswered.


The 74LS08 circuit issue must be a wiring one. CrossRoads on Dec 29, Once you see sn74ls08n datasheet outputs from the AND gates acting like they should, hook them up to the sn74ls08n datasheet stage. Make sure you are identifying pin 1 correctly and counting the pins in datssheet correct direction.

I’ve got some logic gates from Texas Instruments and would like to understand why the left circuit doesn’t sn74ls08n datasheet while the right one works well and.

The key to troubleshooting these kind of problems is to break sn74ls08n datasheet down to their essentials and add stages only after what you start with is working properly.

CMOS is symmetrical and you can drive loads either way. A complete newbie question here: Sn74ls08n datasheet Brattain Member Posts: Look for I OH. The 74LS05 circuit cannot work as that’s an open-collector chip – the outputs can only sink current, not source it.


Terminate to High or Low as needed. Darasheet meant you could make use of the breadboard bus marked with a blue line. Here are the datasheets: I am snn74ls08n using any resistors. Sign up or log in Sign up using Sn74ls08n datasheet. Disconnect everything but power and ground.

sn74ls08n datasheet All logic circuits need decoupling as a matter of course, right next to each chip. Check with a DVM to make sure you have things hooked up correctly and that the voltage is correct.

I’m not using any of the AND gates. Glad things are working sn74ls08n datasheet. Make sure power’s on pin 14 and ground is on pin 7.

Power it with 5V. You are sn74ls08n datasheet decoupling caps on your chips BTW – don’t get into that bad habit, nF ceramic for each chip is a good starting point.
