LM556/NE556 Dual 555 Timer

LM556 have dual timing circuit is a highly-stable controller capable of producing accurate time delays or oscillation. Timing is provided by an external resistor and capacitor for each timing function. The two timers operate independently of each other, sharing only VCC and ground.

Features:

• Direct Replacement for SE556/NE556
  
• Timing From Microseconds Through Hours
  
• Operates in Both Astable and Monostable Modes
  
• Replaces Two 555 Timers
  
• Adjustable Duty Cycle
  
• Output Can Source or Sink 200 mA
  
• Output and Supply TTL-Compatible
  
• Temperature Stability Better Than 0.005% per °C
  
• Normally On and Normally Off Output
  

Applications:

• Precision Timing
  
• Pulse Generation 
  
• Sequential Timing
  
• Time Delay Generation
  
• Pulse Width Modulation
  
• Pulse Position Modulation
  
• Linear Ramp Generator
  
• It is used as a voltage comparator
