APPLICATION INFORMATION  
astable operation  
As shown in Figure 12, adding a second resistor, R to the circuit of Figure 9 and connecting the trigger input  
B,  
to the threshold input causes the timer to self-trigger and run as a multivibrator. The capacitor C will charge  
through R and R and then discharge through R only. The duty cycle may be controlled, therefore, by the  
A
B

values of R and R  
A
B.  
This astable connection results in capacitor C charging and discharging between the threshold-voltage level  
(0.67V ) and the trigger-voltage level (0.33V ). As in the monostable circuit, charge and discharge  
CC  
CC  
times (and therefore the frequency and duty cycle) are independent of the supply voltage.
