MC14029BCP屬于集成電路（IC）的計數(shù)器除法器。由安森美半導(dǎo)體公司制造生產(chǎn)的MC14029BCP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。

Binary/Decade Up/Down Counter

The MC14029B Binary/Decade up/down counter is constructed with MOS P?channel and N?channel enhancement mode devices in a single monolithic structure. The counter consists of type D flip?flop stages with a gating structure to provide toggle flip?flop capability. The counter can be used in either Binary or BCD operation. This complementary MOS counter finds primary use in up/down and difference counting and frequency synthesizer applications where low power dissipation and/or high noise immunity is desired. It is also useful in A/D and D/A conversion and for magnitude and sign generation.
