Functional Features

The SN74AC564N is an octal D-type flip-flop with 3-state outputs. It is designed to store and transfer data in digital systems. The flip-flop has a clock pulse input (CP) that controls the timing of data storage and transfer. It also features a master reset input (MR) for clearing all flip-flop outputs simultaneously. The output enable input (OE) allows the user to disable the outputs when necessary.

Advantages and Disadvantages

Advantages: - High-speed operation - Low-power consumption - 3-state outputs provide flexibility in connecting multiple devices

Disadvantages: - Limited voltage range (2V to 6V) - Maximum power dissipation of 500mW

Working Principles

The SN74AC564N operates based on the principles of digital logic. When a clock pulse is applied to the CP input, the data present at the D0-D7 inputs is transferred to the corresponding Q0-Q7 outputs. The master reset input (MR) can be used to clear all flip-flop outputs to a known state. The output enable input (OE) controls whether the outputs are active or in a high-impedance state.

Detailed Application Field Plans

The SN74AC564N is commonly used in various digital systems, including:

  1. Microprocessors and microcontrollers
  2. Data storage and retrieval systems
  3. Communication systems
