Functional Features

  • Transparent Latching: The 74ACT11373DW allows data to pass through the latch transparently when the latch enable (LE) input is high.
  • Output Enable Control: The output enable (OE) input can be used to disable all outputs, putting them in a high-impedance state.
  • 3-State Outputs: Each output (Q0-Q7) can be independently controlled to be either high, low, or in a high-impedance state.
  • High-Speed Operation: The IC is designed for high-speed digital applications, with a typical propagation delay of 4.5ns.

Advantages and Disadvantages

Advantages: - High-speed operation suitable for time-critical applications. - Flexible output control with 3-state outputs. - Octal latch design provides multiple storage and output options.

Disadvantages: - Requires external control signals (LE and OE) for proper operation. - Limited voltage range of 0V to 5.5V may not be suitable for all applications.

Working Principles

The 74ACT11373DW operates based on the principles of digital logic. When the latch enable (LE) input is high, the data inputs (D0-D7) are transparently passed through to the outputs (Q0-Q7). The output enable (OE) input can be used to disable all outputs, putting them in a high-impedance state. This allows for flexible signal control and prevents conflicts when multiple devices are connected together.

Detailed Application Field Plans

The 74ACT11373DW can be used in various applications that require high-speed digital signal storage and output. Some potential application fields include:

  1. Data Communication Systems
  2. Microprocessor Interfacing
  3. Memory Addressing
  4. Register Storage
  5. Bus Control and Arbitration
