Pin 3 (GND): Ground pin, used to complete the circuit's electrical path. Pin 4 (Y): This is the output pin. It provides the inverted version of the input signal applied to pin A. Pin 5 (NC): This is a no-connection pin. It is not used in the functionality of the IC and should not be connected to anything.

Circuit Principle:

The SN74LVC1G14DCKR is a single-inverter IC from the LVC (Low-Voltage CMOS) logic family. The inverter takes an input signal and produces the opposite logic state on the output. For example:

If the input (A) is HIGH (logic 1), the output (Y) will be LOW (logic 0). If the input (A) is LOW (logic 0), the output (Y) will be HIGH (logic 1).

This simple inverter can be used in a variety of logic operations in digital circuits.
