Functional Features

  • The 74ACT573SCX is designed to latch and store data from the input pins.
  • It has a transparent latch enable (LE) input that allows data to be transferred to the outputs when enabled.
  • The output enable (OE) input controls the 3-state outputs, allowing them to be either active or in high-impedance state.
  • This IC operates at high-speed, making it suitable for applications requiring fast data transfer.

Advantages and Disadvantages

Advantages: - High-speed operation - Octal latch with 3-state outputs - Suitable for various digital systems - Easy integration into existing circuits

Disadvantages: - Limited operating voltage range (4.5V to 5.5V) - Propagation delay time may affect timing-sensitive applications

Working Principles

The 74ACT573SCX works by latching and storing data from the input pins when the latch enable (LE) input is activated. The stored data can then be transferred to the outputs when the output enable (OE) input is enabled. The 3-state outputs allow the IC to be disconnected from the bus when not in use, preventing any interference with other devices.

Detailed Application Field Plans

The 74ACT573SCX is commonly used in various digital systems, including:

  1. Microprocessors and microcontrollers
  2. Data storage systems
  3. Communication equipment
  4. Industrial automation systems
  5. Automotive electronics

Detailed and Complete Alternative Models

Some alternative models that can be considered as alternatives to the 74ACT573SCX are:

  1. 74HC573: Similar octal transparent latch with 3-state outputs, but operates at a lower voltage range (2V to 6V).
  2. 74LS573: Octal transparent latch with 3-state outputs, compatible with TTL logic levels.
  3. CD74ACT573: Another octal transparent latch with 3-state outputs, but from a different manufacturer.

These alternative models offer similar functionality and can be used as replacements depending on specific requirements.
