As shown in Figure 12, adding a second resistor, RB, to the circuit of Figure 9 and connecting the trigger he 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.

图12显示了添加第二电阻、RB为9、数字电路连接触发他即将投入使计时器自我启动,成为multivibrator. 通过收费的电容器CRB、RA、RB,只有通过排放. 因此,控制工作循环RA和RB的价值.
