Functional Features

The SN74AS823ADWR is an 8-bit D-type flip-flop with 3-state outputs. It is designed to store and transfer data in digital systems. The flip-flop has a clear input (CLR) to reset all the outputs to a low state. The output enable input (OE) allows the outputs to be put into a high-impedance state, enabling multiple devices to share a common bus.

Advantages and Disadvantages

Advantages: - High-speed operation - Low-power consumption - 3-state outputs for bus sharing

Disadvantages: - Limited operating temperature range (-40°C to +85°C) - Requires external components for proper functionality

Working Principles

The SN74AS823ADWR operates based on the principles of digital logic. When the clear input (CLR) is activated, all the outputs are set to a low state. Data can be loaded into the flip-flop by applying the desired values to the data inputs (D0-D7) and then triggering the clock signal. The outputs (Q0-Q7) will reflect the loaded data. The output enable input (OE) controls whether the outputs are active or in a high-impedance state.

Detailed Application Field Plans

The SN74AS823ADWR is commonly used in various digital systems, including:

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