LM556  
Dual Timer  
General Description  
Features  
n Direct replacement for SE556/NE556  
n Timing from microseconds through hours  
The LM556 Dual timing circuit is a highly stable controller ca-  
pable of producing accurate time delays or oscillation. The  
556 is a dual 555. Timing is provided by an external resistor  
and capacitor for each timing function. The two timers oper-  
ate independently of each other sharing only VCC and  
ground. The circuits may be triggered and reset on falling  
waveforms. The output structures may sink or source  
200mA.  
n Operates in both astable and monostable modes  
n Replaces two 555 timers  
n Adjustable duty cycle  
n Output can source or sink 200mA  
n Output and supply TTL compatible  
n Temperature stability better than 0.005% per ˚C  
n Normally on and normally off output  
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
