SUMMARY

The NE555 timer can be used as a substitute for the LM555 timer in PWM circuit applications. Both timers are fundamentally similar, although variations in voltage requirements exist among different CMOS versions. Users may need to modify their circuits accordingly if they switch between these versions. The NE555 is readily available from suppliers like Jaycar and Altronics in Australia.

PREREQUISITES
  • Understanding of PWM circuit design
  • Familiarity with NE555 and LM555 timer specifications
  • Knowledge of CMOS technology and its voltage requirements
  • Basic electronics components and sourcing in Australia
NEXT STEPS
  • Research NE555 timer specifications and compare them with LM555
  • Learn about modifying PWM circuits for different timer versions
  • Explore CMOS timer variations and their voltage requirements
  • Investigate local electronics suppliers like Jaycar and Altronics for component availability
USEFUL FOR

Electronics hobbyists, circuit designers, and anyone looking to implement PWM circuits using alternative timer components.

Homework Statement


Hi, I am trying to make a PWM circuit that calls for a LM555 timer but I only have easy access to NE555 timers (In Australia) and am wondering if it will suffice??

Thanks for any help, circuit found here: http://www.rmcybernetics.com/projects/DIY_Devices/homemade_signal_generator2.htm

The Attempt at a Solution

 
Physics news on Phys.org
The prefix is partly determined by the name of the manufacturer.

See the list on this site:
http://en.wikipedia.org/wiki/LM555
Many manufacturers make a version of the 555.

There are various CMOS versions which use different voltages to the LM555 and NE555 so you would have to modify the circuit to use them.

For your query, though, the LM555 and the NE555 are essentially the same.

I see Jaycar and Altronics both carry the NE555. (I'm in Perth).
