MC14040B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MC14040B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。

The MC14040B 12?stage binary counter is constructed with MOS P?Channel and N?Channel enhancement mode devices in a single monolithic structure. This part is designed with an input wave shaping circuit and 12 stages of ripple?carry binary counter. The device advances the count on the negative?going edge of the clock pulse. Applications include time delay circuits, counter controls, and frequency?driving circuits.
