For monostable operation, any of these timers can be connected as shown in Figure 9. If the output is low, application of a negative-going pulse to the trigger (TRIG) sets the flip-flop (Q goes low), drives the output high, and turns off Q1. Capacitor C then is charged through RA until the voltage across the capacitor reaches the threshold voltage of the threshold (THRES) input. If TRIG has returned to a high level, the output of the threshold comparator resets the flip-flop (Q goes high), drives the output low, and discharges C through Q1.

对于单稳态操作,任意一个计时器都可以按照图9所示连接。如果输出为低,用一个反向脉冲给TRIG可以触发触发器(Q变低电平),使输出变高电平,并关掉Q1。电容C于是通过RA充电,直到电容上的电压达到阈值输入端(THRES)的阈值电压。如果TRIG回复高电平,那么阈值比较器的输出端复位触发器(Q变高电平),使输出端输出低电平,并使C向Q1放电。
