Working Principles

The SN74HC02DBR is a quad 2-input NOR gate that performs logical NOR operations on its inputs. It utilizes high-speed CMOS technology, allowing for fast and efficient data processing. The Schmitt-trigger input ensures reliable operation by providing noise immunity.

When both inputs of the NOR gate are low (logic 0), the output is high (logic 1). If any of the inputs are high (logic 1), the output becomes low (logic 0). This behavior follows the truth table of a NOR gate.
