MC14538BFELG集成电路（IC）的多谐振荡器规格书PDF中文资料

MC14538BFELG属于集成电路（IC）的多谐振荡器。由安森美半导体制造生产的MC14538BFELG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。

The MC14538B is a dual, retriggerable, resettable monostable multivibrator. It may be triggered from either edge of an input pulse, and produces an accurate output pulse over a wide range of widths, the duration and accuracy of which are determined by the external timing components, CX and RX. Output Pulse Width T = RX • CX (secs)

RX = Ω

CX = Farads
