Description
The SN74LS07N is a hex buffer/driver integrated circuit from Texas Instruments, designed for use in digital circuits. It contains six independent buffers, each with a high-voltage open-collector output, making it suitable for interfacing with high-level circuits or driving high-current loads. The SN74LS07N operates within a supply voltage range of 4.75V to 5.25V, making it compatible with TTL logic levels.
Key features include its ability to sink up to 40mA per output, allowing it to drive LED displays or other loads without additional amplification. It has a typical propagation delay of 9ns, ensuring fast signal processing, and a maximum power dissipation of around 500mW, which is efficient for many applications. The open-collector outputs require pull-up resistors to function correctly, providing flexibility in connecting to different voltage levels.
The SN74LS07N is commonly used in applications such as LED driving, level shifting, and other interfacing roles in digital systems. It's housed in a standard 14-pin DIP package, making it easy to integrate into breadboards and standard PCBs.

Pinout
The SN74LS07N is a hex buffer/driver IC with open-collector outputs. It has a total of 14 pins. Each of the six buffers/drivers in the IC has an input and an open-collector output, which means it can drive loads connected to a higher voltage than the IC's supply voltage. The open-collector configuration requires an external pull-up resistor for proper operation, which allows for level shifting and wired-AND logic functions.
Here’s a brief description of the pin configuration:
- Pins 1, 3, 5, 9, 11, and 13: Inputs for each of the six buffer/drivers.
- Pins 2, 4, 6, 8, 10, and 12: Corresponding open-collector outputs for each buffer/driver.
- Pin 7: Ground (GND) - the reference voltage for the IC.
- Pin 14: VCC - the supply voltage for the IC.
The SN74LS07N is often used in applications requiring high-current drive and voltage level conversion.
