Functional Features

  • Octal transparent D-type latches with 3-state outputs
  • Latch enable (LE) input for data storage
  • Clock input (CLK) for latch operation
  • Output enable (OE) input for controlling the output state
  • High-speed operation with a maximum frequency of 125MHz
  • Low power consumption
  • Wide operating voltage range (4.5V to 5.5V)
  • 3-state outputs allow multiple devices to share a common bus

Advantages and Disadvantages

Advantages: - High-speed operation allows for efficient data processing - Low power consumption helps in reducing energy usage - Wide operating voltage range provides flexibility in various applications - 3-state outputs enable easy sharing of data buses between multiple devices

Disadvantages: - Limited number of outputs (8 in total) - Not suitable for applications requiring a higher number of outputs or complex logic operations

Working Principles

The SN74ACT563PW operates as an octal transparent D-type latch. When the latch enable (LE) input is high, the data inputs (D0-D7) are transferred to the outputs (Q0-Q7) on the rising edge of the clock input (CLK). The output enable (OE) input controls the output state, allowing the outputs to be either active or in a high-impedance state.

Detailed Application Field Plans

The SN74ACT563PW can be used in various digital logic applications, including but not limited to: - Data storage and transfer in microcontrollers and microprocessors - Address decoding in memory systems - Bus interface control in communication systems - State machine implementation in digital circuits - Control signal generation in industrial automation
