MC14020B集成电路（IC）的计数器除法器规格书PDF中文资料

MC14020B属于集成电路（IC）的计数器除法器。由安森美半导体公司制造生产的MC14020B计数器，除法器计数器和除法器 IC 是数字逻辑器件，可对输入发生的逻辑转换进行计数，然后使用多个并行输出重新发送累加的计数，和/或生成单个输出信号转换，从而对应用某些整数数量输入信号转换进行响应。除了简单的事件计数，它们还可用于各种频率合成应用。

14-Bit Binary Counter

The MC14020B 14−stage binary counter is constructed with MOS P−Channel and N−Channel enhancement mode devices in a single monolithic structure. This part is designed with an input wave shaping circuit and 14 stages of ripple−carry binary counter. The device advances the count on the negative−going edge of the clock pulse. Applications include time delay circuits, counter controls, and frequency−dividing circuits.
