HCF4510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HCF4510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

HCF4510B is a monolithic integrated circuit fabricated in Metal Oxide Semiconductor technology available in DIP package.

It is a PRESETTABLE BCD UP/DOWN COUNTER consists of four synchronously clocked D-type flip-flops (with a gating structure to provide T-type flip-flop capability) connected as a counter. This counter can be cleared by a high level on the RESET line, and can be preset to any binary number present on the jam inputs by a high level on the PRESET ENABLE line.
