NE555 is a widely used Timer IC available in any local electronics components store. This IC performs time and delay functions in different modes, which are Monnostable, astable and bistable configuration. Most electronics hobbyists and students are purchasing this IC for doing hobby electronics Projects. The major applications of using this IC is Pulse generation, Time delay circuit and PWM signal generation.
Features of NE555 Timer
- Fast turn off time of less than 2 seconds
- The IC is able to generate high frequencies around 500 KHz.
- In the timing control circuit it can handle microseconds to several hours.
- The IC can operate in different modes of circuit as Monostable ( one shot pulse) and astable mode (continuous oscillation).
- The output will be around 200mA,this is great for Transistor or Mosfet operation.
