Figure 11. Output Pulse Duration vs Capacitance
Astable Operation
As shown in Figure 12, adding a second resistor, RB, to the circuit of Figure 9 and connecting the trigger input to
the threshold input causes the timer to self-trigger and run as a multivibrator. The capacitor C charges through
RA and RB and then discharges through RB only. Therefore, the duty cycle is controlled by the values of RA and
RB.
This astable connection results in capacitor C charging and discharging between the threshold-voltage level
(
≉0.67 × VCC) and the trigger-voltage level (≉0.33 × VCC). As in the monostable circuit, charge and discharge
times (and, therefore, the frequency and duty cycle) are independent of the supply voltage.
