LINEAR INTEGRATED CIRCUIT  
SINGLE TIMER  
„
DESCRIPTION  
The UTC NE555 is a highly stable timer integrated circuit. It can  
be operated in both Astable and Monostable mode. With monostable  
operation, the time delay is precisely controlled by one external and  
one capacitor. With a stable operation as an oscillator the frequency  
and duty cycle are both accurately controlled with two external  
resistors and one capacitor.  
„
FEATURES  
*High current driver capability(=200mA).  
*Adjustable duty cycle.  
*Timing from μs to hours.  
*Turn off time less than 2μs.  
*Operates in both astable and monostable modes.

Note 1: Supply current when output high typically 1mA less at VCC=5V.  
Note 2: Tested at VCC=5.0V and VCC=15V.  
Note 3: This will determine the maximum value of RA+RB for 15V operation, The maximum total is R=20MΩ, and for  
5V operation the maximum total is R=6.7MΩ.

TYPICAL APPLICATION NOTES  
The application circuit shows astable mode configuration.  
Pin 6 (Threshold ) is tied to Pin 2 ( Trigger ) and Pin 4 ( reset ) is tied to VCC ( Pin 8 ). The external capacitor C1 of  
Pin 6 and Pin 2 charges through RA, RB and dischages through RB only. In the internal circuit of UTC NE555 , one  
input of the upper comparator is at voltage of 2/3Vcc(R1=R2=R3),another input is connected to Pin 6.As soon  
as C1 is charging to higher than 2/3Vcc, transistor Q1 is turned ON and discharge C1 to collector voltage of  
transistor Q1. Therefore, the flip-flop circuit is reset and output is low. One input of lower comparator is at voltage of  
1/3Vcc, discharge transistor Q1 turn off and C1 charges through RA and RB. Therefore, the flip-flop circuit is set  
output high.  
That is, when C1 charges through RA and RB , output is high and when C1 discharge through RB ,output is low.  
The charge time(output is high) t1 is 0.693(RA+RB) C1 and the discharge time (output is low) T2 is 0.693 RB*C1.

T1=0.693*(RA+RB)*C1  
T2=0.693*RB*C1  
Thus the total period time T is given by  
T=T1+T2=0.693(RA+2RB)*C1.
