M74HC4520集成电路（IC）的计数器除法器规格书PDF中文资料

M74HC4520属于集成电路（IC）的计数器除法器。由意法半导体集团制造生产的M74HC4520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。

DESCRIPTION

The M74HC4520 is an high speed CMOS DUAL BINARY COUNTER fabricated with silicon gate C2MOS technology.
