Applications
The SN74S09NE4 is used in digital logic circuits requiring AND gate functions with open-collector outputs, such as bus arbitration, interrupt request lines, and wired-OR/AND bus implementations. Its open-collector outputs allow multiple devices to share a common bus line with a single pull-up resistor, making it popular in I2C-like communication interfaces and level-shifting applications. The DIP-14 package makes it ideal for prototyping, educational electronics projects, and through-hole PCB designs.

Frequently Asked Questions
What is special about the open-collector outputs of the SN74S09NE4?
The SN74S09NE4 features open-collector outputs, meaning the output transistor can sink current but requires an external pull-up resistor to define the high logic level. This enables wired-AND connections where multiple outputs share one bus line, allows voltage translation to levels higher than the supply voltage, and supports direct driving of LEDs and optocouplers with up to 20 mA sink current.
What logic family does the SN74S09NE4 belong to?
The SN74S09NE4 belongs to the Schottky TTL (S) logic family, identified by the 'S' in the part number. Schottky TTL uses Schottky-clamped transistors to reduce transistor saturation and improve switching speeds compared to standard TTL. The S family supports 15 pF load capacitance and delivers fast propagation delays suitable for high-speed digital logic systems.
How many AND gates are in the SN74S09NE4?
The SN74S09NE4 contains 4 independent 2-input AND gates in a single 14-pin DIP package. Each gate operates independently with its own input and open-collector output pins, allowing all four gates to be used simultaneously in different parts of the same circuit, maximizing component utilization in logic designs.
What package is the SN74S09NE4 available in?
The SN74S09NE4 is available in a 14-pin PDIP (Plastic Dual In-line Package), a through-hole package well-suited for prototyping and breadboarding. The DIP footprint is compatible with standard IC sockets, making it easy to replace components during development. The 'NE4' suffix indicates the standard commercial temperature range version.
