74AHC(T)123A: 双可再触发单稳态多谐振荡器，带重置

74AHC123A；74AHCT123A是高速硅栅CMOS器件，与低功耗肖特基TTL (LSTTL)针脚兼容。其规格符合JEDEC标准no. 7A。

74AHC123A；74AHCT123A是输出脉冲宽度由三种方法控制的双可再触发单稳态多谐振荡器。基本脉冲时间通过选择外部电阻(REXT)和电容(CEXT)进行编程。

一旦触发，基本输出脉冲宽度可通过再触发门控低电平有效边沿输入(nA)或高电平有效边沿输入(nB)进行扩展。重复这一过程，就可按需形成输出脉冲周期（nQ为高电平，nQ 为低电平）。或者，输出延迟可通过输入nRD上的低电平沿随时终止，其还可抑制触发。

从nRD到输入门的内部连接使其可以通过输入nRD上的正向信号触发电路。基本输出脉冲宽度实质上由外部定时元件REXT和CEXT的值确定。CEXT ≥ 10 nF时，典型输出脉冲宽度定义为：tW= REXT× CEXT，其中tW= 脉冲宽度（单位：ns）；REXT= 外部电阻（单位：kΩ）；CEXT= 外部电容（单位：pF）。所有输入处的施密特触发器动作使电路高度容许较慢的输入上升和下降时间。
