M74HC123集成电路（IC）的多谐振荡器规格书PDF中文资料

M74HC123属于集成电路（IC）的多谐振荡器。由意法半导体集团制造生产的M74HC123多谐振荡器多谐振荡器是简单的双态器件，尽管它们的典型使用方式在很大程度上具有模拟特性，但通常被认为是数字逻辑元器件。单稳型也称为“单发”，具有一种稳定状态；但施加触发信号可使它们离开此状态一段时间，该时间通常由所连接电容器的值来确定。这些器件对于去弹跳开关触头等应用非常有用。非稳型没有稳定状态，在两个状态之间按一定频率持续转换，该频率通常也是由所连接电容器的值来确定。

DESCRIPTION

The M54/74HC123 is a high speed CMOS MONO-STABLE multivibrator fabricated with silicon gate C2MOS technology. It achieves the high speed operation similar to equivalent LSTTL while maintaining the CMOS low power dissipation.
