74HC32 Quad 2-Input OR Gate IC (SMD Package)

Where an AND gate needs both inputs true, an OR gate only needs one, a different but equally common piece of combinational logic for building up decision circuits without a microcontroller. The 74HC32 packs four independent 2-input OR gates onto a single chip, and this SMD-package version is sized for a finished surface-mount PCB design rather than breadboard prototyping.
