HCF4520BEY屬于集成電路（IC）的計數(shù)器除法器。由意法半導(dǎo)體集團(tuán)制造生產(chǎn)的HCF4520BEY計數(shù)器，除法器計數(shù)器和除法器 IC 是數(shù)字邏輯器件，可對輸入發(fā)生的邏輯轉(zhuǎn)換進(jìn)行計數(shù)，然后使用多個并行輸出重新發(fā)送累加的計數(shù)，和/或生成單個輸出信號轉(zhuǎn)換，從而對應(yīng)用某些整數(shù)數(shù)量輸入信號轉(zhuǎn)換進(jìn)行響應(yīng)。除了簡單的事件計數(shù)，它們還可用于各種頻率合成應(yīng)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.
