40106 IC CMOS Hex Schmitt Triggers

Description

40106 IC CMOS
Hex Schmitt Triggers

The
CD40106 IC
consists of six Schmitt-Trigger inputs. Each circuit functions as an inverter with Schmitt-Trigger input. The trigger switches at different points for positive- and negative-going signals. The difference between the positive-going voltage (VP) and the negative-going voltages (VN) is defined as hysteresis voltage (VH).

Where to use CD40106 IC:

The CD40106 is a hex inverter Schmitt trigger, meaning it has 6 inverted Schmitt triggers inside it. A Schmitt trigger is used to avoid the problem of hysteresis. It can also be used to smoothen a noisy single into a sharp one. Schmitt trigger gate can convert sinusoidal or triangular wave to square wave. It can also be used as a logic inverter if needed. A Schmitt trigger is also useful for debouncing a push button 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 CD40106 IC ?

As mentioned earlier CD40106 has six INVERTING SCHMITT TRIGGER GATES which can be used as six individual gates. CD40106 internal structure is given 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.

Applications:

Wave and Pulse Shapers

High-Noise-Environment Systems

Monostable Multivibrators
