+---+--+---+ OE1 |1 +--+ 20| VCC D0 |2 19| D7 D1 |3 18| GND D2 |4 17| Q7 D3 |5 16| Q6 D4 |6 15| Q5 D5 |7 14| Q4 D6 |8 13| Q3 LE |9 12| Q2 CLK |10 11| Q1 +----------+

Functional Features

  • Octal transparent latch: The SN74F573N can store and output data on its eight D-type latches.
  • 3-state outputs: The outputs can be disabled using the OE1 input, allowing multiple devices to share a common bus.
  • TTL-compatible inputs: The inputs are compatible with TTL logic levels, making it easy to interface with other digital components.
  • High-speed operation: The SN74F573N is designed for high-speed applications, with a maximum propagation delay of 6ns.

Advantages and Disadvantages

Advantages: - High-speed operation allows for efficient data transfer in time-critical applications. - 3-state outputs enable bus sharing, reducing the number of required pins. - Wide operating voltage range provides flexibility in different power supply configurations.

Disadvantages: - Limited to octal latch functionality, may not be suitable for applications requiring more or fewer latch outputs. - DIP package may not be suitable for space-constrained designs.

Working Principles

The SN74F573N operates as an octal transparent latch. When the latch enable (LE) input is high, the data on the D0-D7 inputs is transferred to the Q0-Q7 outputs. The outputs remain latched until the LE input goes low. The outputs can also be disabled by setting the output enable (OE1) input high, putting them in a high-impedance state.

Detailed Application Field Plans

The SN74F573N 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

In these applications, the SN74F573N is utilized for data storage, bus interfacing, and signal buffering purposes.
