NE556 Dual Timer IC

The NE556 dual monolithic timing circuit is a highly stable controller capable of producing precise time delays or oscillations. Operating as a time delay, the time is accurately controlled by one external RC (resistor/capacitor)network.
For a stable operation as an oscillator, the free running frequency and theduty cycle are both set with two external resistors and one capacitor.
The circuits may be triggered and reset on falling waveforms, and the output structure can source or sink up to 200 mA.


  • Low turn-off time
  • Maximum operating frequency greater than 500 kHz
  • Timing from microseconds to hours
  • Operates in both astable and monostable modes
  • Output can source or sink up to 200 mA
  • Adjustable duty cycle
  • TTL compatible
  • Temperature stability of 0.005% per °C
