7409 Quad 2-Input AND Gate Logic IC (Open-Collector) – DIP-14

The 7409 is a TTL logic integrated circuit containing four independent 2-input AND gates with open-collector outputs in a single package. It performs standard AND logic functions while providing flexible output interfacing through external pull-up resistors. The open-collector design allows wired-AND connections, direct interfacing with higher-voltage circuits, and driving external loads such as LEDs or relays. Operating from a standard 5V TTL supply, the 7409 is commonly used in logic control, signal gating, level shifting, and digital interface applications.
