Functional Features

  • Hex inverter gate: The 74AHCT04APWJ consists of six independent inverters, each capable of converting a high-level input signal into its complementary low-level output.
  • High-speed operation: With a propagation delay time of only 10 ns, this IC ensures fast signal processing.
  • Low-power consumption: The quiescent current of 4 μA (maximum) makes it suitable for power-sensitive applications.
  • Compatibility with TTL levels: The IC is designed to be compatible with TTL (Transistor-Transistor Logic) levels, allowing seamless integration with existing TTL-based systems.

Advantages and Disadvantages

Advantages: - High-speed operation enables quick signal processing. - Low-power consumption makes it suitable for battery-powered devices. - Compatibility with TTL levels allows easy integration into existing systems.

Disadvantages: - Limited output current may restrict its use in high-current applications. - Restricted supply voltage range may limit compatibility with certain systems.

Working Principles

The 74AHCT04APWJ operates based on the principle of digital logic inversion. Each of the six independent inverters takes an input signal and produces the complementary output. When the input is at a high level (logic 1), the output will be at a low level (logic 0), and vice versa. This functionality allows for signal inversion and logical operations within digital circuits.
