Hallo!I am begginer in robotics.I want to built a simple robot like the electric cricket...But i dont have the 74hc14 or 74hct240,but i have these:
1. SN74LS245N
2. 74LS365AN
3. SN74LS14N
4. T74LS02B1
5. T74LS10B1
6. T74LS00B1
7. T74LS04B1
8. CD4093BCN
9. CD4002BCN
10. 74HC86N
and much more!Can i built any robot with one of these?
Sorry for my english!
a what?
I have no idea what a 74hc14 is. Not all of us know these numbers by heart. What o you know about it? Why would you use it for a robot?
Perhaps if you told us these thing, we could help you find alternatives.
good thing about digital
good thing about digital logic is that you can do any logic gate with any of the others
you can change the 74ls14 ( schmitt-trigger inveter ) with the 4093 ( 2-input NAND Schmitt trigger), short the inputs and it will work just like a inverter
Basically i want to built
Basically i want to built this http://www.ralfschreiber.com/solarsound/solarsound.html electronic cricket but i dont have the 74hc14 chip.Can i use the SN74LS245N insead of?
not if you jus want to copy the circuit
Only if you’re wanting to do some learning, would you be able to change one component for another. When your variation of the recipe does not work, how would know what went wrong?
If you just want to build this thing and show it off to others, go with the original. Or find something else.
Your original part number
Your original part number (74hc14) is a hex inverting schmitt trigger. You can look up the datasheet of this part, and look through your available parts to see if you have something functionally similar. The SN74LS245N is not an inverter, so it probabably won’t work for this design.
Take a look at the part numbers you listed. Notice any that look similar to the original part? Like perhaps item #3 (SN74LS14N)?
It helps if you know a bit about how parts are numbered. Two parts with the same number codes perform the same function. So 74HC14 and SN74LS14N are both 74xx14 parts: hex schmitt trigger inverters. Read this Wikipedia article for info on the differences between the derivative families of the 7400 series parts.
**this and this should help. **
this and this should help. Now normally you can replace any 74*14 chip with any other, however since your application is solar powered TTL devices will be far too power hungry to work. this should explain the different families to you, but suffice to say the HC and 4000 series devices are cmos which is far more energy efficient than your 74ls14.
Thank you…But i am newbie
Thank you…But i am newbie in electronics,so i wonder is there any way to connect the SN74LS245N to produce the ‘‘same’’ sound?
I’d really advise you to do
I’d really advise you to do some reseach on your own at this point. You have a design you are trying to replicate, only with different parts. You have a pile of parts. You have an Internet connection with access to Google.
Seach for the datasheet for each part you have and see if any of them are hex inverters like the 74HC14 you are trying to replace. As already mentioned by another member, you want a low power part, either a 7400 series HC or a CMOS 4000 series. You could also try searching for CMOS hex inverter and see which part numbers come up.
You keep asking if you can make this cricket circuit with the SN74LS245N. If your goal is to make the cricket circuit work, you are asking the wrong question.
It sounds like for some strange reason want to create a completely different circuit that has a similar effect to the cricket circuit only using an octal line driver like the SN74LS245N. That does not seem like a very acheivable goal.
However, doing the reseach on each of the parts that you have will help you learn what different functions are available on those chips. Then you might find all sorts of interesting circuits to build with them, and learn a lot in the process.
