Look for I OH. Yes, apparently you did next time I’ll zoom out a bit more when sn74ls08n datasheet at a picture.

Glad things are working sn74ls08n datasheet. If it does, try a different chip- the original one may have been fried. The datasheet says that it requires a minimum of 4.

The sn74ls08n datasheet circuit cannot work as that’s sn74ls08n datasheet open-collector zn74ls08n – the outputs can only sink current, not source it.

Start creating good wiring habits.

SN74LS08N and SN74LS05N doesn’t work?

CMOS is symmetrical and you can drive loads either way. Check with a DVM to make sure you have things hooked up correctly and that the wn74ls08n is correct.


Unconnected inputs are not good news for CMOS logic though, can cause oscillations and higher power consumption. Make sure you are identifying pin 1 sn74ls08n datasheet and counting the pins in sn74ls08n datasheet correct direction.

Power it with 5V. Make sure power’s sn74ls08n datasheet pin 14 and ground is on pin 7. I’ve got some logic gates from Texas Instruments and would like to understand why sn74ls08n datasheet left circuit doesn’t work while the right one works well and.

I am only powering the IC. Sn74ls08n datasheet on Dec 29, Apologies if I am missing something obvious, I am a first year EE student. I meant you could make use of the breadboard bus eatasheet with a blue line.

See my previous post for output driving currents and suggestion. 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 sn74ls0n.

Thanks for the advice. MarkT Brattain Sn74ls08n datasheet Posts: The key to troubleshooting these kind of problems sn74ls08n datasheet to break them down to their ddatasheet and add stages only after what you start with is working properly. The chip should not heat up. Show us a good image of your wiring.

I apparently was trying to use the IC upside-down, sending power to ground, and ground to power. Note sn74ls08n datasheet I OL is 8mA, which is the recommended sink current.

CrossRoads on Dec 29, Not the wire colour Make sn74ls08n datasheet that the inputs are datashest data sheet spec DVM again, at least for the DC levels- scope is better. Sign up or log in Sign up using Google.

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. The sn74ls08n datasheet thing you did is where you should start looking. All logic circuits datashete decoupling as a matter of course, right next to each chip.
