LM555/NE555/SA555  
Single Timer  
Features  
Description  
• High Current Drive Capability (200mA)  
• Adjustable Duty Cycle  
• Temperature Stability of 0.005%/°C  
• Timing From µSec to Hours  
The LM555/NE555/SA555 is a highly stable controller  
capable of producing accurate timing pulses. With a  
monostable operation, the time delay is controlled by one  
external resistor and one capacitor. With an astable  
• Turn off Time Less Than 2µSec  
operation, the frequency and duty cycle are accurately  
controlled by two external resistors and one capacitor.  
Applications  
8-DIP  
• Precision Timing  
• Pulse Generation  
• Time Delay Generation  
• Sequential Timing
