Product Description

The 74LS04 Hex Inverter IC is a fundamental digital logic component containing six independent NOT gates within a single 14-pin package. Each gate performs the Boolean function $Y = \bar{A}$, effectively "flipping" the input signal—if the input is HIGH (1), the output becomes LOW (0), and vice versa. Utilizing Low-power Schottky (LS) technology, this IC provides high-speed signal inversion with minimal power consumption. It is an essential tool for digital electronics, commonly used for signal conditioning, pulse stretching, creating clock oscillators, and as a logic-level buffer in various computing and robotic applications.

Key Features

  • Six Independent Inverters: A single chip provides six separate NOT operations, offering high density for complex logic boards.

  • High-Speed Performance: Features a typical propagation delay of ~10ns, making it suitable for high-frequency digital circuits.

  • Standard TTL Compatibility: Designed for 5V systems, making it directly compatible with Arduino, 8051, and other TTL-logic microcontrollers.

  • Low Power Consumption: The "LS" design ensures thermal efficiency even during continuous high-speed switching.

  • Universal DIP-14 Package: Fits perfectly into standard breadboards and 14-pin IC sockets for easy prototyping and repair.

Technical Details

  • Propagation Delay: ~10ns to 15ns.

  • Operating Temperature: 0°C to +70°C.

  • Pin Configuration: Pin 14 (VCC), Pin 7 (GND).

Prototyping and Engineering Tips from Robogears

  • Signal "Flipping" Logic: CRITICAL: The 74LS04 is often used to convert an "Active High" signal to "Active Low" (or vice-versa). For example, if your sensor outputs 5V when triggered, but your motor driver needs 0V to stop, the 74LS04 acts as the perfect interface.

  • Creating a Simple Oscillator: You can create a basic square-wave clock generator by connecting an odd number of inverters (usually 3 or 5) in a ring with a resistor and capacitor. This is a classic "Ring Oscillator" used in introductory digital electronics labs.

  • Unused Inverter Inputs: Never leave input pins of unused gates floating. Floating inputs act like tiny antennas that pick up noise, leading to high power consumption or erratic behavior. Always tie unused inputs to Ground (GND) or VCC.

  • Decoupling is Key: Like all 74-series logic, the 74LS04 can create switching noise on the power rail. Always place a 0.1µF Ceramic Capacitor between Pin 14 and Pin 7, as close to the chip as possible, to ensure clean logic transitions.

  • Driving Loads: The 74LS04 is a logic gate, not a power driver. While it can light up a small indicator LED (with a 220-330Ω resistor), do not attempt to drive relays or motors directly from the pins. Use a transistor like the 8050 to handle higher current loads.

Disclaimer: Product images are shown for illustrative purposes only. The exact color of the knobs or the branding placement on the chassis may vary slightly between manufacturing batches, but all technical specifications and the 850A performance standards remain as described. This disclaimer also applies to any included accessories such as nozzles and stands.

Safety Warning: Ensure your power supply is regulated to a stable 5V. Voltages above 7V will instantly destroy the internal silicon structure. Always verify the IC orientation using the notch on the plastic housing to identify Pin 1 before applying power.
