Working Principles

The SN74LVC14ADGVR is based on CMOS technology, which uses complementary pairs of MOSFETs to implement logic functions. It operates as an inverting Schmitt trigger, which means that the output signal is the logical inverse of the input signal. The Schmitt-trigger inputs ensure noise immunity by employing positive feedback and hysteresis.

When the input voltage crosses the upper threshold, the output switches to the opposite logic level. Similarly, when the input voltage falls below the lower threshold, the output switches back to the original logic level. This hysteresis prevents false triggering due to noise or slow input transitions.
