The problems you saw were because voltage dividers make a very poor power supply.

Datasheet: 74LS04

Oct 21, Messages: Feb 1, Messages: Do you datasheet 74ls04 have an account? I will have to somehow simulate it How much current these pins conduct? Nov 20, Messages: I think it will help a lot of people like me. I just saw someone else using it so I also used datasheet 74ls04

Any voltage reg sheet will do far better than this datasheet 74ls04 they include a voltage reference and amplifier rather than a divider. You must log in or sign up to reply here.

Tanks – 0 means Tank is empty Input Incoming water is 1, datasheet 74ls04 water is coming. I do google to get this circuit satasheet never understands it so I thought of going with my own logic. Here I had used a capacitor of micro farad and Datasheet 74ls04 have no idea Why?


How to read a datasheet (74LS04)

This is the way we learn. When water comes I will get a signal means some current will flow and when Tank 1 is full I will get a signal as the float will complete datashert ciruit similarly for tank2 and tank 3. Jan 12, Messages: The above logic does not have any direct Gate?

Quiescent current datasheet 74ls04 something like 3 to 6mA. I just need that if I am giving datasheet 74ls04 current to Pin 1 then Pin 2 should not give any current.

I will wind up now before this becomes too confusing. I am a consultant on AS and a Retail datasheet 74ls04 expert. The gates in this chip provide TTL logic outputs which are a must in some applications. When power is properly established, right polarity, right voltage, datasheet 74ls04 battery, datashedt the inputs must be considered.

Datasheet 74ls04 let me know how to make it work. Cmos should be used instead. Discussion in ‘ General Electronics Chat ‘ datasheet 74ls04 by mdfrahim1Dec 3, Then I am using a rectifier combination of 4 datasheet 74ls04 and a capacitor to convert it to 15V DC. Wire that in series with your incoming water sensor normally open. I am vatasheetI should have mentioned the complete scenario.


I will build the circuit 2. I was using IC because this way 1. To participate you need to register. Dec 2, Messages: When I measue it without an ICi get a correct reading!!!!! Used a Breadboardconnected the IC with a 4. This site uses cookies to help personalise content, tailor your experience and to keep you logged in if you register.

Thanks a lot Eric. Is it possible the supply voltage 4.

I mean is the IC supposed to do this? I suspect you’re not finding pin 1 correctly, or your voltmeter is seriously flawed. Under OFF sate the total supply voltage datasheet 74ls04 across the transistor.

Thanks eric and Matc for your replies. Choose the appropriate package depending on requirement.

datashheet Joking aside, batteries will power TTL logic just fine – but don’t use it in something you hope to operate datasheet 74ls04 months datasheet 74ls04 a time. No, create an account now.
