CMOS is symmetrical and you can drive loads either way. Unconnected inputs are not good news for CMOS sn74ls08n datasheet though, can cause oscillations and higher power consumption.
Sn74ls08n datasheet sn7l4s08n 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. Power it sn74ls08n datasheet 5V. Sign up or log in Sign up using Google. This is the recommended operating current that can be sourced.
Once you see the outputs from the Sn74ls08n datasheet gates acting like sn74ls08n datasheet should, hook them up to the next stage. CrossRoads on Dec 29, I am only powering the IC. The last thing you did is where you should start looking.
BobT 4 7. Sn74ls08n datasheet 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.
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 sn74ls08h. Sn74ls08n datasheet chip should not heat up.

Read times previous topic – next topic. The 74LS05 circuit cannot work dataasheet that’s an open-collector chip – the outputs can only sink current, not source it. If it does, try a different chip- the original one may have been fried. Note that I OL is 8mA, which is the recommended sink current. Sign up sn744ls08n Facebook.

You are lacking decoupling caps on your chips BTW datasgeet don’t get into that bad habit, nF ceramic for each chip is a good starting point.
LarryD on Dec 29, Sn744ls08n am not using any resistors. Thanks for the advice.

See my previous post for output driving currents and suggestion. Look for I OH. Yes, apparently you did next time I’ll zoom out a bit more when looking at a picture.
I’m not using any of the AND sn74ls08n datasheet. A complete newbie question here: Start creating good wiring habits. I hope this quality is good enough. Disconnect everything but sn74ls08n datasheet and ground.

That sn74ls08n datasheet tend to let the magic smoke out Glad things are working now. Check with a DVM to make datasheer you have things hooked up correctly and that the voltage sn74ls08n datasheet correct. The 74LS08 circuit issue must be a wiring one.
