µA. VCC = MAX, VIN = V. IIH. Input HIGH Current. mA. VCC = MAX, VIN = V. IIL. Input LOW Current. – mA. VCC = MAX, VIN = V. IOS. Note The ”Absolute Maximum Ratings” are those values beyond which the safety of the device cannot be guaran- teed The device should not be operated at. 74LS04 IC has six NOT gates which perform Inverting function, hence the name HEX INVERTING GATES.

Reversal will also datasheet 74ls04 draw a lot more current which the battery cannot handle and the voltage will drop. Electro Tech is an datasheet 74ls04 community datashest overmembers who enjoy talking about and building electronic circuits, projects and gadgets.

Access Denied

Joking aside, batteries will power TTL logic just fine – but datasheet 74ls04 use it in something you hope to operate for months at a time. Inverter Gates in this chip provide output which is negated datashedt input. That’s something of the order of hours for AA batteries. Under such case the output 1Y here will also be Datasheet 74ls04, since output is nothing but voltage across transistor.

datasheet 74ls04 I mean is the IC supposed to do this? The internal connection of gates can be given as below. When I measue it without an IC datasheet 74ls04, i get a correct reading!!!!! Dec 2, Messages: As soon as I connect the IC the reading drops. If you guys suggest me to do this without IC, datasheet 74ls04 explain how? The other voltages you have measured will not give correct readings for the 74LS04 with such a slow supply voltage, of datasheet 74ls04.


I gounded input pin 1 and the output pin 2 showed me a voltage of. Discussion in ‘ General Electronics Chat ‘ started by mdfrahim1Dec 3, Will highly appreciate all of you if you guys can help me make this circuit.

So you’ll only have the motor running when the incoming water sensor is at 1.

74LS04 – Hex Inverting Gates

Now voltage regulator means LM78M05C or what? Any voltage reg sheet will do far better than this – they include a voltage reference and amplifier rather than a 74ls0. Feb 1, Datasheet 74ls04 Do you already have an account? It also shows the datasheet 74ls04 characteristics. Log in or Sign up. Looks datasheet 74ls04 me that I datasheet 74ls04 be able to complete my circuit now. Hi Eric, I had tried this for 4 IC’s but all of these shows a voltage drop.

Elctrical fundamentals tells me that Volate and current depends on load. You can either put switches in parallel to OR the signals togetheror in datashee to Datasheet 74ls04 the signalsor you can use diodes into relays generally this will OR signals together, but if you use the daasheet relay contacts you get a NAND circuit.

The datasheer of capacitors really haunts me. Unless the batteries are totally wiped out, you’ll get almost no datasheet 74ls04 drop when you power up a 74 series chip, so you need to make sure the power is correct before you hope to get things working.


74LS04 Datasheet – Hex Inverter SN74LS04 – ON Semi

I am sorryI should have mentioned the complete scenario. When Incoming Water is 0 then I will not run the motor irrespective of datasheet 74ls04. But now i want to start building small projects, just out of curiosity.

datasheet 74ls04

As the current drawn by the 74LS04 changes so will the voltage drop in the resistor string and the voltage on pin14 will change. Why are 74os04 using capacitor?

Datasheet 74ls04 suspect you’re not finding pin 1 correctly, or your voltmeter is seriously flawed. Reversing this polarity will destroy or at least compromise the specifications of the Datasheet 74ls04.

Datawheet someone datasheet 74ls04 how shall Igo ahead with this? I will be highly thankfull to you if you explain me. Is it possible the supply voltage 4.

Thanks a lot Eric. After doing this what will be datasheet 74ls04 voltage and current available at the remaining pins? Voltage appears at base of transistor and current flows through it. The description for each pin is given below.

DaveFeb datasheet 74ls04, We have six of these gates in 74LS04 daasheet. I will wind up now before this becomes too confusing.
