The LM555 is a highly stable device for generating accurate time delays or oscillation. It operates in 2 modes: monostable mode and astable mode. In monostable mode, the time is precisely controlled by one external resistor and capacitor; For astable operation as an oscillator, the free-running frequency and duty cycle are accurately controlled with two external resistors and one capacitor.
LM555 Application
  1. Precision timing
  2. Pulse generation
  3. Sequential timing
  4. Time delay generation
  5. Pulse width modulation
  6. Pulse position modulation
  7. Linear ramp generator
