74LS09 IC Quad 2-Input AND Gate with Open-Collector Output DIP-14 74LS09

Product Overview

The 74LS09 is a digital logic device containing four independent 2-input AND gates. Unlike standard AND gates, these feature open-collector outputs, which require an external pull-up resistor to achieve a HIGH logic level. This design is particularly useful for implementing wired-AND configurations, interfacing with different voltage levels, or driving loads that require higher voltage/current than a standard TTL output can provide.
