MC74HC4040ADT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MC74HC4040ADT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(duì)輸入發(fā)生的邏輯轉(zhuǎn)換進(jìn)行計(jì)數(shù)，然后使用多個(gè)并行輸出重新發(fā)送累加的計(jì)數(shù)，和/或生成單個(gè)輸出信號(hào)轉(zhuǎn)換，從而對(duì)應(yīng)用某些整數(shù)數(shù)量輸入信號(hào)轉(zhuǎn)換進(jìn)行響應(yīng)。除了簡(jiǎn)單的事件計(jì)數(shù)，它們還可用于各種頻率合成應(yīng)用。

12-Stage Binary Ripple Counter

High?Performance Silicon?Gate CMOS

The MC74C4040A is identical in pinout to the standard CMOS MC14040. The device inputs are compatible with standard CMOS outputs; with pullup resistors, they are compatible with LSTTL outputs.

This device consists of 12 master?slave flip?flops. The output of each flip?flop feeds the next and the frequency at each output is half of that of the preceding one. The state counter advances on the negative?going edge of the Clock input. Reset is asynchronous and active?high.

State changes of the Q outputs do not occur simultaneously because of internal ripple delays. Therefore, decoded output signals are subject to decoding spikes and may have to be gated with the Clock of the HC4040A for some designs.
