MC14018BCP集成電路（IC）的計數(shù)器除法器規(guī)格書PDF中文資料

MC14018BCP屬于集成電路（IC）的計數(shù)器除法器。由安森美半導體公司制造生產(chǎn)的MC14018BCP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)生的邏輯轉換進行計數(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換，從而對應用某些整數(shù)數(shù)量輸入信號轉換進行響應。除了簡單的事件計數(shù)，它們還可用于各種頻率合成應用。

The MC14018B contains five Johnson counter stages which are asynchronously presettable and resettable. The counters are synchronous, and increment on the positive going edge of the clock.

Presetting is accomplished by a logic 1 on the preset enable input. Data on the Jam inputs will then be transferred to their respective Q outputs (inverted). A logic 1 on the reset input will cause all Q outputs to go to a logic 1 state.

Division by any number from 2 to 10 can be accomplished by connecting appropriate Q outputs to the data input, as shown in the Function Selection table. Anti?lock gating is included in the MC14018B to assure proper counting sequence.
