SN7407N Hex Buffer Driver IC

The SN7407N is a high-voltage, high-current hex buffer/driver integrated circuit featuring six independent non-inverting buffers with open-collector outputs. This versatile IC is designed for applications requiring high output drive capability, level shifting, and interface buffering between different logic families. The open-collector outputs can sink substantial current, making it ideal for driving LEDs, relays, optocouplers, and other high-current loads.

Each buffer can handle output voltages up to 30V when used with appropriate external pull-up resistors, enabling easy interfacing between low-voltage logic circuits and higher voltage devices. The non-inverting configuration ensures that the output logic state matches the input, simplifying circuit design. With TTL-compatible inputs, the SN7407N works seamlessly with microcontrollers, Arduino boards, and other digital logic circuits.

Perfect for applications such as LED matrix driving, relay control, bus line buffering, motor control interfaces, and voltage level translation, this IC provides robust performance with built-in protection features. The standard 14-pin DIP package ensures easy breadboard prototyping and PCB integration. Whether you’re designing industrial control systems, automation projects, or hobby electronics, the SN7407N offers reliable buffering and driving capabilities with the flexibility of open-collector outputs.
