CD40106 HEX Inverter: Pinout, Applications and Datasheet

The CD40106 IC consists of six Schmitt-Trigger inputs. Each circuit functions as an inverter with Schmitt-Trigger action on the 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). 

The CD40106 device is supplied in ceramic packaging (J) as well as standard packaging (D, N, NS, PW). All CD40106B devices are rated for –55°C to 125°C ambient temperature operation.

Texas Instruments CD40106BE technical specifications, attributes, parameters and parts with similar specifications to Texas Instruments CD40106BE.

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.

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.
