NE556 Dual Timer Integrated circuit 556 Timer 14 Pin DIP

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  operation,  the  time  is  precisely  controlled  by one  external  resistor  and  capacitor.  For  a  stable operation  as  an  oscillator,  the  free  running  frequency  and  the  duty  cycle  are  both  accurately controlled with two external 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°C
  
  
  

The NE556 timer is one of the most popular timing ICs. With just a few external components a variable time interval or oscillator can be made.
