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

QAR 2.00/ unit

Description

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. Features • Quad 2-input AND gate configuration • Four independent logic gates • Open-collector outputs for flexible interfacing • Supports wired-AND logic connections • External pull-up resistor compatibility • Standard TTL logic compatibility • Single 5V supply operation • Suitable for higher-voltage interfacing • Can drive indicator loads and control circuits • Reliable TTL switching performance • DIP-14 through-hole package • Breadboard-friendly design • Easy PCB integration • Ideal for digital logic applications
