Discussion Overview

The discussion revolves around the use of a 555 timer in a circuit designed to output a "high" signal for a duration of 10 seconds when a momentary switch is pressed and released. Participants explore configurations, tutorials, and resources related to the 555 timer, particularly in the context of battery pulsing applications.

Discussion Character

  • Technical explanation
  • Conceptual clarification
  • Homework-related

Main Points Raised

  • One participant inquires about using a 555 timer to create a circuit that outputs a "high" signal for 10 seconds upon pressing a momentary switch.
  • Another participant suggests using the 555 timer in a monostable configuration as a potential solution.
  • A participant mentions the availability of datasheets as tutorials and provides a link to a Fairchild datasheet for the 555 timer.
  • Discussion shifts to the availability of data/application books from semiconductor manufacturers, with mixed experiences shared by participants regarding obtaining these resources.
  • Additional web tutorials for the 555 timer are shared, along with a reference to its use in a battery pulsing desulfator circuit by one participant.

Areas of Agreement / Disagreement

Participants generally agree on the availability of datasheets and tutorials for the 555 timer, but there is no consensus on the best approach to achieve the desired circuit functionality or on the accessibility of application books from manufacturers.

Contextual Notes

Some participants express uncertainty about the current practices of semiconductor manufacturers regarding the distribution of application books and datasheets, indicating a potential change over time.

Can 555 timer be use to make a circuit that outputs "high" for 10 when a momentary switch is pressed and released? How?

Is there an easy 555 timer tutorial?

Yes, use the 555 timer in a monostable configuration.

All ICs have "tutorials" called datasheets. Here's one from Fairchild that should contain all the info you need:

Data Sheets

Chroot,

If I'm remembering correctly, once you said you worked for National Semiconductor? Anyway, after reading your post, I went over to my reference book shelf and pulled out an old National data sheet with lots of applications when they first introduced the LM324 quad op amp. I used that little booklet many, many times while designing analog circuits back in those days.

I don't think semiconductor manufactures hand out data/application books for free like they use to.

Have you every used these op amps before?

Regards

Sure they do. To get the books just call a company rep. I've gotten the manuals for the 12 and 16 series PICs from microchip as well as many pubs from vishay, fairchild, dallas(maxim), Atmel... Also just go to the corporate web sites and you'll find all of the data sheets in PDF format. I've not encountered an electronic component that I couldn't get a detailed data sheet for. Most manufactures offer slim data sheets for indiviadual components and much more detailed data sheets for families of components. If you call a rep they will encourage you to download the PDF's because there are times when the electronic file is more up-to-date then what the rep will have on hand but if you ask they will usually send you what they have.
