Functional Features

  • Octal D-type transparent latch with 3-state outputs
  • Latch enable (LE) and clock (CLK) inputs control the data transfer
  • Data inputs (D0-D7) store the input data when LE is high and CLK transitions from low to high
  • Outputs (Q0-Q7) reflect the stored data when OE (output enable) is low
  • 3-state outputs allow multiple devices to share a common bus

Advantages and Disadvantages

Advantages: - High-speed operation - Low power consumption - Wide supply voltage range - 3-state outputs for bus sharing

Disadvantages: - Limited number of inputs and outputs - Not suitable for applications requiring complex logic functions

Working Principles

The SN74AC563DWRE4 is an octal D-type transparent latch that stores and transfers data in digital systems. When the latch enable (LE) input is high and the clock (CLK) input transitions from low to high, the data inputs (D0-D7) are stored in the latch. The stored data is then reflected on the outputs (Q0-Q7) when the output enable (OE) input is low.

The 3-state outputs of the latch allow multiple devices to share a common bus, enabling efficient communication between different components in a digital system.

Detailed Application Field Plans

The SN74AC563DWRE4 can be used in various applications, including but not limited to:

  1. Microprocessor-based systems
  2. Data storage and transfer systems
  3. Communication equipment
  4. Industrial automation
