This document describes the features and characteristics of DM74ALS09 Quad 2-Input AND Gate with Open Collector Outputs, including its four independent gates, the requirement of external pull-up resistors for logical operation, the adoption of advanced oxide-isolated, ion-implanted Schottky TTL process, compatibility with Schottky and low power Schottky TTL counterparts, and improved AC performance.
The DM74ALS09 is a quad 2‑input AND gate featuring open‑collector outputs that require external pull‑up resistors. It is fabricated using an advanced oxide‑isolated, ion‑implanted Schottky TTL process and is pin‑compatible with standard Schottky TTL devices.
The datasheet provides absolute maximum ratings, recommended operating conditions, electrical characteristics, switching times, and detailed mechanical dimensions for both SOIC (M14A) and PDIP (N14A) packages. Ordering codes and life‑support policy information are also included.
