The LM556CMX is a highly stable controller capable of producing accurate time delays or oscillation. The 556 is a dual 555. 

• 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 200mA

  
  

• Output and supply TTL compatible

  
  

• Temperature stability better than 0.005% per ˚C

  
  

• Normally on and normally off output
