HCF4520BEY集成电路（IC）的计数器除法器规格书PDF中文资料

HCF4520BEY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HCF4520BEY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 HCC4518B/4520B (extended temperature range) and HCF4518B/4520B (intermediate temperature range) are monolithic integrated circuits, available in 16-lead dual in-line plastic or ceramic package and plastic micro package. The HCC/HCF4518B Dual BCD Up Counter and HCC/HCF4520B Dual Binary Up Counter each consist of two identical, internally synchronous 4-stage counters.
