This is a general purpose Dual Bipolar Timer.



The NE556 dual monolithic timing circuit is a highly stable controller capable of producing accurate time delays or oscillation. In the time delay mode of op-eration, the time is precisely controlled by one exter-nal resistor and capacitor.

For a stable operation as an oscillator, the free running frequency and the duty cycle are both accurately controlled with two exter-nal resistors and one capacitor. The circuit may be triggered and reset on falling waveforms, and the output structure can source or sink up to 200mA.


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


  • Supply Voltage(VCC):4.5 to 18V
  • Maximum Input Voltage:VCC
