CD40106 - Hex Schmitt Trigger Inverter IC

CD40106 - Hex Schmitt Trigger Inverter IC 

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 voltage (VN) is defined as hysteresis voltage (VH).

A Schmitt trigger input means that the threshold voltage for going from a HIGH to a LOW input is different from the threshold for going from LOW to HIGH.

CD40106 Pinout Configuration:

Pin Number	Pin Name	Description
1,3,5,11,13,15	Schmitt Input Pins	Input pins of the Schmitt trigger
2,4,6,10,12,14	Schmitt Inverted Output Pins	Output pins of the Schmitt trigger
7	Ground	Connected to the ground of the system
14	Vcc (+5V)	Resets all outputs as low. Must be held high for normal operation

Applications of CD40106:

• Noise removing circuits
• Debouncing circuits
• Hysteresis controller
• Dead band filter
