Where to use MC14584:

The MC14584B Hex Schmitt Trigger is constructed with MOS P−channel and N−channel enhancement mode devices in a single monolithic structure. It has6 inverted Schmitt triggersinside it. A Schmitt trigger is used to avoid the problem ofhysteresis. It can also be used to “square up” slowly changing waveforms. It can also be used as a logic inverter if needed. A Schmitt trigger is also useful for驱动按钮or other noisy input devices.

So if you are looking for an IC which can help you to get of switching noise or to create sharp square wave signals based on an input signal then this IC could be the right choice or you.

How to Use MC14584

As mentioned earlier MC14584 has six Inverting Schmitt Trigger Gates which can be used as six individual gates. The simplified internal structure can be given as below.

Each of these 6 gates can be used individually based on our application. Since the gates are inverting we can also combine two gates to form a non-inverting gate. The input signal can be a noise square wave or any signal wave that oscillates between the low and high hysteresis voltage.

Schmitt触发器的独特和特殊功能是根据输入信号切换输出，而无需任何噪声。这是通过使用内部没有切换的滞后带来实现的。切换时间测试电路和波形如下：
