LM555  
Timer  
General Description  
Features  
n Direct replacement for SE555/NE555  
n Timing from microseconds through hours  
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 re-  
sistor 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.  
n Operates in both astable and monostable modes  
n Adjustable duty cycle  
n Output can source or sink 200 mA  
n Output and supply TTL compatible  
n Temperature stability better than 0.005% per ˚C  
n Normally on and normally off output  
n Available in 8-pin MSOP package  
Applications  
n Precision timing  
n Pulse generation  
n Sequential timing  
n Time delay generation  
n Pulse width modulation  
n Pulse position modulation  
n Linear ramp generator
