This is the recommended operating current that can be sourced. Home Questions Tags Users Unanswered. I don’t understand, why OUT green cable still “high” and the LED on even sn74le08n both inputs yellow cables are off here both are on.

MarkT Brattain Member Posts: Once you see the outputs from the AND gates acting like they should, hook them up to the next stage. Start creating good wiring habits. LarryD on Sn74,s08n 29, 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. CrossRoads on Dec 29, The last thing you did is where you should start looking. That would tend to let the magic smoke out Look for I OH.

I hope this quality is good enough. The chip should not heat up.

CMOS is symmetrical and you can drive loads either way. Not the wire colour Apologies if I am missing something obvious, I am a first year EE student.

Thanks for the advice.

Read times previous topic – next topic. 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. I meant you could make use of the breadboard bus marked with a blue line.

SN74LS08N and SN74LS05N doesn’t work?

I’ve got some logic gates from Texas Instruments and would like to understand why the left zn74ls08n doesn’t work while the right one works well and. I apparently was trying to use the IC upside-down, sending power to ground, and ground to power. Power it with 5V.

I am only powering the IC.

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.
