SN74LS06 Hex Inverted Buffers with Open-Collector Outputs

The SN74LS06 is a versatile integrated circuit from Texas Instruments, designed to provide efficient and reliable logic-level conversion and buffering solutions. This chip is part of the 74LS series, which is well-known for its low-power Schottky technology, offering a perfect blend of speed and power consumption.

Key Features

  • Open-Collector Outputs: The SN74LS06 features six independent buffers with open-collector outputs, which allows for multiple outputs to be connected together to achieve wired-AND logic configurations.
  • Voltage Compatibility: With an operating voltage range of 4.75V to 5.25V, this device is compatible with standard TTL (Transistor-Transistor Logic) levels, making it suitable for interfacing with other TTL logic devices.
  • Drive Capability: The open-collector outputs can sink up to 40 mA, enabling the device to drive LEDs, relays, or other high-current loads directly.
  • High Impedance: The high-impedance NPN transistor output stage provides a significant advantage when used in wired-AND logic schemes.


The SN74LS06 is commonly used in a wide range of applications including:

  • Logic level conversion
  • Buffering and driving heavy loads
  • Interfacing with high-voltage or high-power circuits
  • Creating wired-AND logic configurations

Quality and Reliability

Texas Instruments is known for its commitment to quality, and the SN74LS06 is no exception. It is designed to meet or exceed the stringent requirements of the industrial and commercial markets, ensuring reliable performance in a variety of conditions. The device is available in multiple package options, including the standard DIP (Dual In-line Package) and SOIC (Small Outline Integrated Circuit), providing flexibility in design and application.

Whether you are designing a complex digital system or simply need a robust buffer for your logic signals, the SN74LS06 from Texas Instruments is a reliable choice that combines performance with practicality.
