FEATURES  
DESCRIPTION  
The LM555 is a highly stable device for generating  
accurate time delays or oscillation. Additional  
terminals are provided for triggering or resetting if  
desired. In the time delay mode of operation, the time  
is precisely controlled by one external resistor and  
capacitor. For astable operation as an oscillator, the  
free running frequency and duty cycle are accurately  
controlled with two external resistors and one  
capacitor. The circuit may be triggered and reset on  
falling waveforms, and the output circuit can source  
or sink up to 200mA or drive TTL circuits.
