MC14018B集成電路（IC）的計(jì)數(shù)器除法器規(guī)格書PDF中文資料

MC14018B屬于集成電路（IC）的計(jì)數(shù)器除法器。由安森美半導(dǎo)體公司制造生產(chǎn)的MC14018B計(jì)數(shù)器，除法器計(jì)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(jì)數(shù)，然后使用多個并行輸出重新發(fā)送累加的計(jì)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(jì)數(shù)，它們還可用于各種頻率合成應(yīng)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.
