74HC02D,653 NEXPERIA Quad 2-Input NOR Gate IC (SOIC-14)

A NOR gate flips the usual logic around, its output only goes high when every input is low, making it the natural fit for building a reset condition, an all-clear signal, or any other logic that needs to react to the absence of active inputs rather than their presence. This genuine Nexperia 74HC02 packs four of these independent NOR gates onto one SOIC-14 chip, built for a finished surface-mount PCB design.
