Circuit Principle:

The CD40106BM96 is used for converting input logic levels into output levels, inverting the signals with Schmitt Trigger behavior. Schmitt triggers are known for their hysteresis, meaning they provide a more stable output in noisy conditions and can be used in environments where inputs may be slow or noisy. The six inverters are independent, and each provides an inverted output with noise filtering.

Each Schmitt trigger within the IC works by comparing the input voltage to its threshold voltage. If the input voltage rises above a defined threshold (upper voltage limit), the output switches to a low state, and vice versa when the input falls below the lower threshold.

This is especially useful in creating reliable and clean digital signals in noisy environments or when signals have slow transitions.
