Pin 1 (接地) -地线(或共同接地) ，通常被连接到电路共同接地。 Pin 2 (触发点) -这个脚位是触发NE555使其启动它的时间周期。触发信号上缘电压须大于2/3 VCC，下缘须低于1/3 VCC 。 Pin 3 (输出) -当时间周期开始555的输出输出脚位，移至比电源电压少1.7伏的高电位。周期的结束输出回到O伏左右的低电位。于高电位时的最大输出电流大约200 mA 。 Pin 4 (重置) -一个低逻辑电位送至这个脚位时会重置定时器和使输出回到一个低电位。它通常被接到正电源或忽略不用。 Pin 5 (控制) -这个接脚准许由外部电压改变触发和闸限电压。当计时器经营在稳定或振荡的运作方式下,这输入能用来改变或调整输出频率。 Pin 6 (重置锁定) - Pin 6重置锁定并使输出呈低态。当这个接脚的电压从1/3 VCC电压以下移至2/3 VCC以上时启动这个动作。 Pin 7 (放电) -这个接脚和主要的输出接脚有相同的电流输出能力，当输出为ON时为LOW，对地为低阻抗，当输出为OFF时为HIGH，对地为高阻抗。 Pin 8 (V +) -这是555个计时器IC的正电源电压端。供应电压的范围是+4.5伏特(最小值)至+16伏特(最大值)。
