74LS33 IC Quad 2-Input NOR Gate DIP-14 74LS33

Product Overview

The 74LS33 is a digital logic device containing four independent 2-input NOR buffer gates. These gates feature open-collector outputs, which require an external pull-up resistor to function correctly. This configuration is commonly utilized for wired-AND applications or to achieve higher output voltage levels ($V_{OH}$) than standard totem-pole output gates.
