Discussion Overview

The discussion revolves around the possibility of designing a NOT gate using the NE555 timer IC. Participants explore the theoretical and practical aspects of this application, including references to datasheets and circuit schematics.

Discussion Character

  • Exploratory, Technical explanation, Conceptual clarification

Main Points Raised

  • One participant inquires about the feasibility of creating a NOT gate with the NE555.
  • Another participant requests a datasheet for the NE555 to investigate potential inversion capabilities, questioning if the inquiry is related to homework.
  • A third participant provides a link to a resource that discusses the NE555, clarifying that their inquiry is not a homework problem.
  • A later reply shares a specific datasheet link and suggests examining the simplified schematic and typical waveforms for clues on achieving an inversion function.

Areas of Agreement / Disagreement

Participants do not appear to reach a consensus on the method for creating a NOT gate with the NE555, and multiple viewpoints regarding the approach remain present.

Contextual Notes

Some assumptions about the circuit design and the interpretation of the datasheet may be missing, and the discussion does not resolve the specific steps needed to implement the inversion function.

is there anyway to Design NOT GATE using NE555?
 
Engineering news on Phys.org
Can you post a link to a datasheet for the 555? Just look on the simplified schematic in the datasheet for the chip to see if you can find any inversion possibilities. BTW, is this a homework problem?

Good, then it's posted in the right forum. Take a look at this datasheet (found it quickly with Google):

http://cache.national.com/ds/LM/LM555.pdf

Look at the simplified schematic of the 555 internal circuit, and then look at the typical waveforms farther down in the Applications section. Do you see how some waveforms go high when others go low, and visa-versa? Ther's your clue to how to make an inversion function...
